 Petro-Chemical, Environmental, Marine, Industrial, Aircraft and Oil & Gas Industries Membrane Nitrogen Generator

In the petroleum and petrochemical industry, inert atmosphere protection is a key safety measure used to prevent oxygen from reacting with flammable or explosive substances, thereby reducing the risk of fire and explosion. Nitrogen, as a commonly used inert gas, plays an important role in this regard.

In petroleum and petrochemical installations and equipment, many processes need to be carried out under high temperature, high pressure or special environment, involving flammable or explosive substances. These substances include petroleum products, petrochemicals, solvents, gases and vapors, etc. When oxygen is present, these substances may burn or explode under certain conditions, resulting in serious accidents and losses.

In order to reduce the risk of fire and explosion, the petroleum and petrochemical industry often adopts inert atmosphere protection technology. Among them, nitrogen is widely used as an excellent inert gas.

• The process of creating an inert atmosphere with nitrogen typically involves the following steps:


• Exclude Oxygen: Reduce the oxygen concentration below safe levels by introducing nitrogen and rapidly removing oxygen from the system. This can be achieved by using an inert gas generator or a nitrogen compressor.


• Maintain an inert environment: Once oxygen has been removed, continue to inject nitrogen into the system to maintain an inert atmosphere. The required inert environment is usually maintained by quantitatively controlling the nitrogen flow.


• Detection and monitoring: regular detection and monitoring of oxygen concentration to ensure the stability of the inert atmosphere. If the oxygen concentration is found to increase, it is necessary to replenish nitrogen in time or take other measures to maintain an inert environment.


• By creating an inert atmosphere, nitrogen effectively prevents oxygen from interacting with flammable or explosive substances, reducing the risk of fire and explosion. This technology is widely used in key equipment and processes such as petroleum and petrochemical plants, storage tanks, pipeline systems, reactors and catalyst beds to ensure their safe operation.

 Working Principle 

 
Membrane technology is based on the use of hollow fibers with a permeable structure. Thousands of these small, straw like plastic fibers are packed together in a tube of stainless steel 316 or coated aluminium. The process of gas separation starts when pressurized air is fed to one end of this tube. The quality of compressed air is important in order to maintain the efficiency of the nitrogen membranes and the purity of the nitrogen. Therefore the compressed air will be filtered. Solids, aerosol, liquid and vapour will be removed by coalescing, active carbon and dust filters. The filtration quality complies with customers’ requirements. The permeation rates of water vapour, CO2, and oxygen contained in the air stream are faster than nitrogen and argon and will rapidly diffuse through the fiber walls (permeate). The slower diffused nitrogen molecules remain in the fiber bore and are collected as the nitrogen product gas (retentate). The air flow rate will determine how much undiffused oxygen remains with the nitrogen gas. The membranes act like a filter with no moving parts and continuously generate nitrogen at selected flow and purity. The number of membrane modules, the compressed inlet air pressure and the temperature determine the capacity and purity of the nitrogen produced. The higher the feed air pressure the higher the nitrogen flow, this increase is more or less linear The produced nitrogen at the requested purity is now free for use in various applications or can be stored in a buffer vessel. The enriched oxygen is exhausted via the permeate outlet to a safe location. The nitrogen generator packages are provided with an oxygen analyzer which measures the quality of the produced nitrogen. In case the produced nitrogen does not meet the requested specification, the off-spec mixture will be vented outside or the package will shut-down completely. Each of our nitrogen generation packages is pre-tested in our workshop to make sure the package meets the requested specification of the client.

Purities up to 99,5%

Membrane nitrogen generator packages are available for purities from 95% up to 99,5%, different pressures and capacities, including air compressors, filters, instrumentation, automatic valves, control panels, buffer vessels, gas boosters for cylinder charging and nitrogen bottle racks. The packages can be installed in safe areas as well as hazardous areas.
