In the petrochemical industry, nitrogen is an “invisible guardian” that ensures production safety and improves process efficiency. From anti-corrosion and explosion-proof measures during crude oil extraction, to process assistance in the refining and chemical sector, and quality protection in oil product storage, the stable supply of nitrogen is directly related to the continuity of enterprises’ production and their economic benefits. However, traditional nitrogen generation methods have plunged many petrochemical enterprises into a predicament: cryogenic air separation for nitrogen generation requires high investment, occupies a large area, and has an extremely slow start – up speed, which is completely unable to meet the demand for emergency nitrogen use; The cost of bottled nitrogen remains high, and frequent cylinder replacement not only increases labor burden but also brings about safety risks…
Just when the industry was troubled by the nitrogen generation problem, Jiangsu Minuo Group Co., Ltd., relying on its years of in – depth research in the fields of PSA (Pressure Swing Adsorption) and membrane separation technology, launched membrane nitrogen generation technology, which is like an “effective remedy”. With its core advantages of “high efficiency, energy conservation, flexibility, and low cost”, it has completely changed the pattern of nitrogen generation in the petrochemical industry. Today, Jiangsu Minuo’s membrane nitrogen generation systems have been put into use in dozens of petrochemical enterprises across the country. From the cold wind of oil fields in Northeast China to the high – temperature workshops of refining and chemical plants in South China, and from oil product storage bases in East China to the routes of gathering and transportation pipelines in Northwest China, the stable operation of these systems can be seen, creating tangible value for enterprises.
I. Bid Farewell to “Bulky and Inefficient”! Membrane Nitrogen Generation Technology Redefines the New Standard of Nitrogen Generation in Petrochemical Industry
For petrochemical enterprises, nitrogen generation systems not only need to “supply enough nitrogen” but also “work well”. Jiangsu Minuo’s membrane nitrogen generation technology, starting from the actual needs of enterprises, breaks through many limitations of traditional nitrogen generation methods and makes nitrogen supply “flexible and worry – free”.
1. Nitrogen Generation upon Start – up, No “Breakdown” in Emergency Situations
In petrochemical production, sudden equipment maintenance and process adjustments often require immediate nitrogen supply. The start – up of a traditional cryogenic nitrogen generation system takes 8 to 24 hours. By the time the system completes the “preheating” process, the optimal processing time may have long passed. In contrast, Jiangsu Minuo’s membrane nitrogen generation system can produce nitrogen that meets the purity standard within 5 to 10 minutes after start – up. It is like an “emergency team that is always on call”, easily coping with emergency nitrogen use scenarios.
Last winter, air entered the casing of an oil well in a North China oilfield, leading to signs of hydrogen sulfide corrosion. If nitrogen was not injected in a timely manner to isolate the air, the oil well might have been scrapped. Jiangsu Minuo’s mobile membrane nitrogen generation system was urgently dispatched to the site. It began to stably supply nitrogen 10 minutes after arriving at the scene. The nitrogen with a purity of 99.5% and a pressure of 0.8MPa was continuously injected, and the corrosion risk was brought under control in just 2 hours. The person in charge of the oilfield sighed: “If we had waited for the cryogenic system to start up, the loss of this oil well would have been enormous! Jiangsu Minuo’s membrane nitrogen generation system is really a ‘timely rain’ for emergency rescue.”
2. Customization on Demand, “Installing” an Efficient System Even in Small Spaces
Many petrochemical enterprises face the problem of tight factory space. The traditional cryogenic nitrogen generation system requires an area of thousands of square meters, which makes enterprises hesitant to adopt it. Jiangsu Minuo’s membrane nitrogen generation system adopts a modular design and can be flexibly combined like “building blocks”. A system with an annual nitrogen output of 1000Nm³/h only needs an area of 50 – 100㎡. It can be easily installed either in the corner of a production workshop or on a simple outdoor platform.
When an East China refining and chemical plant was expanding its catalytic cracking unit, the reserved space for nitrogen generation equipment was very limited. Based on the on – site conditions, Jiangsu Minuo customized a set of compact membrane nitrogen generation systems. These systems not only fit perfectly into the narrow space but also achieved a nitrogen output of 200Nm³/h with a stable purity of 99.9%, providing continuous inert protective gas for the regenerator. After the unit was put into operation, the person in charge of the refining and chemical plant said: “We originally thought that such a small space could not accommodate efficient nitrogen generation equipment. Unexpectedly, Jiangsu Minuo’s solution is so flexible. It not only saves space but also ensures production.”
3. Low Energy Consumption and Durability, “Greatly Reducing” the 10 – year Operation and Maintenance Cost
Petrochemical enterprises attach great importance to “cost reduction and efficiency improvement”, and the energy consumption and operation and maintenance costs of nitrogen generation systems are crucial factors. The high – efficiency hollow fiber membrane modules independently developed by Jiangsu Minuo adopt imported polymer materials and special spinning processes. The nitrogen permeation efficiency is 15% higher than that of traditional membrane modules, and the energy consumption per unit nitrogen production is only 1/3 of that of cryogenic nitrogen generation. More importantly, the service life of these membrane modules is as long as 8 – 10 years. During this period, only regular replacement of filter elements is required, and there is almost no complex maintenance work.
Compared with traditional nitrogen generation methods, Jiangsu Minuo’s membrane nitrogen generation system can help enterprises save a large amount of money. Taking a large – scale oil product storage enterprise as an example, after adopting Jiangsu Minuo’s membrane nitrogen generation and nitrogen sealing system for its 10 diesel storage tanks with a volume of 5000m³ each, the annual electricity cost is only 40% of that of the traditional cryogenic system. In addition to the reduced oil product loss, the enterprise can save more than 1 million yuan in costs every year. The financial director of the storage enterprise said with a smile: “We used to think that nitrogen generation was a ‘major cost item’, but now with Jiangsu Minuo’s system, nitrogen generation has become a ‘helper for saving money’.”
II. Covering the Entire Process! Membrane Nitrogen Generation Technology Solves the “Nitrogen Use Troubles” in All Links of Petrochemical Industry
The production process of the petrochemical industry is complex. From crude oil extraction to oil product transportation, the nitrogen demand varies in each link. Jiangsu Minuo’s membrane nitrogen generation technology, with the characteristics of “adjustable purity, matching flow rate, and flexible deployment”, has become a “universal nitrogen generation solution” covering the entire process of the petrochemical industry.
(I) Crude Oil Extraction: Providing an “Anti – corrosion and Explosion – proof Coat” for Oil Wells
At the crude oil extraction site, the corrosion and explosion risks of oil well casings are major concerns for enterprises. When air enters the casing, oxygen reacts with sulfides in crude oil to form hydrogen sulfide, which accelerates the corrosion of the casing; at the same time, the mixture of air and crude oil vapor may also form an explosive mixture. Injecting high – purity nitrogen can build a “safety barrier” for oil wells.
Jiangsu Minuo’s mobile membrane nitrogen generation system is specially designed for on – site oilfield use and can adapt to the low – temperature environment of – 30℃ and bumpy transportation conditions. In a Northeast China oilfield, two sets of Jiangsu Minuo’s membrane nitrogen generation systems have been in service all year round. They continuously inject nitrogen with a purity of 99.5% into 3 oil wells every day, which not only effectively inhibits hydrogen sulfide corrosion but also avoids explosion risks. The technical personnel of the oilfield calculated an account: compared with the traditional cryogenic nitrogen generation mode that requires the construction of fixed plants and long – distance nitrogen transportation, this system reduces the investment cost by 30%, saves more than 500,000 yuan in annual operation and maintenance costs, and also reduces the nitrogen loss during transportation, realizing “on – site nitrogen generation and immediate protection”.
In the crude oil gathering and transportation link, the residual crude oil in the pipeline is prone to oxidation and coking, which may block the pipeline. Jiangsu Minuo’s membrane nitrogen generation system can quickly provide nitrogen with a purity of 99% to promote the flow of crude oil in the pipeline and reduce the residual amount. After an oilfield in Northwest China adopted this solution for its gathering and transportation pipelines, the pipeline cleaning cycle was extended from 3 months to 6 months, the annual shutdown and cleaning time was reduced by 15 days, and the gathering and transportation efficiency was increased by 20%.
(II) Petroleum Refining and Chemical Engineering: Ensuring “Stable as a Rock” Process Operation
Petroleum refining and chemical engineering is the core link of the petrochemical industry. Processes such as catalytic cracking and hydrofining have extremely high requirements for the purity and stability of nitrogen. Jiangsu Minuo’s membrane nitrogen generation technology, like a “process bodyguard”, ensures the stable operation of refining and chemical units.
1. Catalytic Cracking Unit: Protecting the “Activity” of Catalysts
In the regenerator of the catalytic cracking unit, the catalyst is regenerated at a high temperature. Once the air supply is unstable, it is easy to cause coking and deactivation of the catalyst, which affects the output of light oil. The membrane nitrogen generation system customized by Jiangsu Minuo for a South China refining and chemical plant can continuously provide nitrogen with a purity of 99.9% and a flow rate of 200Nm³/h, stabilizing the bed pressure of the regenerator and preventing overheating of the catalyst. After the system was put into operation, the catalyst loss rate was reduced by 10%, saving the refining and chemical plant more than 800,000 yuan in annual catalyst costs. The operation stability of the unit was increased by 20%, and there was no production interruption due to nitrogen supply problems.
2. Hydrofining Unit: “Double Insurance” for Replacement and Sealing
In the hydrofining process, hydrogen is a key reaction gas. However, during shutdown and maintenance, the mixture of hydrogen and air may cause an explosion. Jiangsu Minuo’s membrane nitrogen generation system can quickly provide nitrogen with a purity of 99.99% to complete the system replacement. Compared with bottled nitrogen, the cost is reduced by 60%, and the trouble of frequent cylinder replacement is also eliminated. At the same time, the nitrogen with a stable pressure of 0.5 – 1.0MPa provided by the system can also be used as the sealing gas for the hydrogenation reactor, preventing the leakage of reaction media, ensuring safety, and avoiding environmental pollution.
3. Equipment Maintenance: Creating a “Safe Operation Environment” for Workers
During the maintenance of storage tanks and towers in refining and chemical plants, the residual oil and gas inside are major safety hazards. Jiangsu Minuo’s membrane nitrogen generation system can flexibly adjust the nitrogen production according to the volume of the equipment to quickly replace the internal oil and gas. When replacing a 1000m³ crude oil storage tank, using a system with a nitrogen production capacity of 100Nm³/h can complete the replacement in only 8 – 10 hours, which is 50% shorter than the time required by the traditional cryogenic nitrogen generation method, greatly reducing the loss caused by maintenance shutdown. The maintenance director of a refining and chemical plant said: “With Jiangsu Minuo’s membrane nitrogen generation system, we no longer have to worry about the oil and gas accumulated inside during maintenance. Workers can operate more safely, and the maintenance progress is also faster.”
(III) Oil Product Storage: Keeping Oil Products “As Fresh as New”
During the storage of oil products, contact with air is prone to oxidation and deterioration, forming colloids and organic acids, which affect the quality of oil products. Jiangsu Minuo’s membrane nitrogen generation and nitrogen sealing system can create an “inert protective layer” in the top space of the storage tank, delaying the oxidation of oil products and extending the storage cycle.
An East China oil product storage enterprise has 20 gasoline storage tanks with a volume of 10,000m³ each. After adopting Jiangsu Minuo’s distributed membrane nitrogen generation solution, each storage tank is equipped with an independent small – sized membrane nitrogen generation unit, which can automatically adjust the nitrogen supply according to the change of the liquid level in the storage tank to maintain a micro – positive pressure environment. After the system was put into operation, the oxidation rate of gasoline was reduced by 30%, the storage cycle of oil products was extended by 2 months, and the annual oil product loss of each storage tank was reduced by 0.5%. Based on the market price of gasoline, the enterprise can save more than 1 million yuan in costs every year. More importantly, the nitrogen utilization rate is increased to 95%, which reduces the nitrogen waste by 30% compared with the centralized nitrogen supply mode, truly realizing “precise nitrogen supply and efficient energy conservation”.
III. Choosing Jiangsu Minuo: More Than Buying a Set of Equipment, but Enjoying “Full – Life – Cycle Services”
In the petrochemical industry, the stable operation of the nitrogen generation system is crucial. Once a fault occurs, it may lead to the shutdown of the entire production line and cause huge losses. Jiangsu Minuo is well aware of this. Therefore, it not only provides high – quality membrane nitrogen generation equipment but also builds a “pre – sales, in – sales, and after – sales” full – life – cycle service system, allowing enterprises to “buy with confidence and use with peace of mind”.
1. Pre – sales: Customization on Demand, No “One – size – fits – all” Solutions
Each petrochemical enterprise has different production processes, site conditions, and nitrogen use demands. Jiangsu Minuo never promotes “standardized products”. Instead, it dispatches a professional technical team to conduct on – site investigations at the customer’s premises. The technical personnel will have a detailed understanding of the enterprise’s requirements for nitrogen purity, pressure, and flow rate, analyze the production working conditions, and even take into account the local climate conditions. Then, through simulation calculations, they will design the most suitable solution.
When designing a solution for a Southwest China refining and chemical plant, the technical team of Jiangsu Minuo found that the local area has high temperature and high humidity in summer, and traditional membrane modules are easily affected by moisture, resulting in a decrease in efficiency. Therefore, the team added a high – efficiency dehumidification module to the solution and optimized the heat dissipation design of the membrane modules to ensure that the system can still operate stably in the high – temperature and high – humidity environment. “Jiangsu Minuo’s team is very professional and considers more than we do. We are confident in such a solution,” said the project director of the refining and chemical plant.
2. In – sales: Full – process Tracking to Ensure “Zero – error Commissioning”
During the equipment manufacturing process, Jiangsu Minuo will regularly feed back the progress to the customer and invite the customer to inspect the factory to let the customer know about the production quality of the equipment. After the equipment is delivered to the site, a professional installation team will quickly complete the installation and commissioning. In addition, one – on – one training will be provided to the enterprise’s operators to ensure that they can skillfully master the operation and daily maintenance methods of the system.
During the installation of the membrane nitrogen generation system in a North China oilfield, it happened to be the rainy season, and the site was muddy and difficult to navigate. Jiangsu Minuo’s installation team worked in the rain, working 12 hours a day. They not only completed the installation on time but also carried out rainproof protection treatment on the equipment. After the commissioning was completed, the team also left 2 technical personnel to conduct on – site guidance for the operators for 3 days and did not leave until everyone could operate independently. “Jiangsu Minuo’s service is very considerate. Both the installation speed and the training effect exceed our expectations,” commented the person in charge of the oilfield.
3. After – sales: 24 – hour Response, No Delay in Problem – solving
To ensure the continuity of enterprises’ production, Jiangsu Minuo has established a 24 – hour emergency response mechanism and set up multiple service outlets across the country. When a customer encounters any problem, they only need to make a phone call, and the technical personnel can arrive at the site within 48 hours (within 72 hours for remote areas) to quickly solve the problem. At the same time, Jiangsu Minuo will also conduct regular inspections on the equipment to detect potential faults in advance and “examine and diagnose” the equipment.
Last summer, the membrane nitrogen generation system of a South China refining and chemical plant suddenly experienced pressure fluctuations. At that time, the catalytic cracking unit was operating at full load, and the nitrogen supply could not be interrupted. The refining and chemical plant urgently contacted Jiangsu Minuo, and the after – sales team arrived at the site within 2 hours. After investigation, it was found that the problem was caused by the blockage of the filter element. The filter element was replaced in only 30 minutes, and the system returned to normal operation. “The after – sales response speed of Jiangsu Minuo is really fast. If it had been a little later, our catalytic cracking unit might have had to shut down. They really helped us avoid huge losses,” said the equipment manager of the refining and chemical plant.
IV. The Future is Here! Jiangsu Minuo Leads Membrane Nitrogen Generation Technology to Assist the “Green Transformation” of the Petrochemical Industry
With the advancement of the national “dual carbon” goals, the petrochemical industry is moving towards the direction of “greenization, intelligence, and high efficiency”. As a leading enterprise in membrane nitrogen generation technology, Jiangsu Minuo is also continuously innovating to inject new impetus into the green transformation of the petrochemical industry.
In terms of technological research and development, the R & D team of Jiangsu Minuo has never stopped. The recently launched “intelligent variable load control system” can collect the enterprise’s nitrogen demand data in real – time through sensors and automatically adjust the nitrogen production of the system, avoiding energy waste caused by “excessive nitrogen production”. Compared with the traditional fixed – load system, the energy saving rate can reach 15% – 20%. At the same time, the team is also developing “high – purity membrane modules”, which will be able to achieve the preparation of nitrogen with a purity of more than 99.9995% in the future, meeting the production needs of high – end chemical products.
In terms of intelligence, Jiangsu Minuo’s membrane nitrogen generation system will be integrated with the Internet of Things (IoT) technology. Customers can check the operating parameters of the system (nitrogen production purity, pressure, energy consumption, etc.) in real – time through a mobile APP or a computer terminal. They can also receive fault early warning information to realize “remote monitoring and predictive maintenance”. In the future, the system can also be linked with the production control system (DCS) of petrochemical enterprises to realize the intelligent matching between nitrogen supply and production load, making the entire production process more efficient and energy – saving.
The general manager of Jiangsu Minuo Group said: “We have always firmly believed that technological innovation is the core driving force for the development of the industry. In the future, Jiangsu Minuo will continue to deepen its research in membrane nitrogen generation technology, provide more efficient, energy – saving, and intelligent nitrogen generation solutions for petrochemical enterprises, assist the petrochemical industry in achieving green and low – carbon development, and create a better future together with customers.”
