PSA Oxygen Plant for Oil And Gas
Oil and Gas usually has an oxygen output of 3-300 Nm³/h or above. For example, our NTK93 oxygen generator has an oxygen output of 3-300 Nm³/h. Some other equipment can produce thousands of cubic meters per hour. The specific output depends on the scale of oil and gas production and oxygen demand.
Oxygen purity
Generally required to be around 90%-95%, some special processes may require higher purity oxygen, such as some natural gas catalytic conversion processes.
Oxygen pressure
The outlet pressure is usually between 0.1-0.6 MPa, which can meet the pressure requirements of different process links in the oil and gas industry. For example, in the catalytic cracking unit of petroleum refining, the oxygen introduced needs a certain pressure to promote the regeneration of the catalyst.
Dew point temperature
The oxygen outlet dew point is generally required to be **≤-43℃**, and special requirements can reach below - 60℃ to prevent the adverse effects of water condensation on the equipment and process during subsequent pipeline transportation and use.
Air handling capacity
It is related to oxygen production, generally above 3-300 m³/h, to ensure that there is enough air to obtain the required amount of oxygen after separation.
Equipment power
The power of the equipment depends on factors such as oxygen production and air compressor power, generally ranging from several kilowatts to tens of kilowatts. For example, the power of the OW-2TB PSA oxygen generator is relatively small, while the power of large industrial equipment is larger.

Dimensions and weight
Dimensions and weight vary depending on the output and configuration of the equipment. For example, the 3-300 oxygen generator of Hangzhou Fuyang Tianao Air Separation Equipment Co., Ltd. has dimensions of 2200X1300X1700mm and weighs 900kg.
Operation noise
The noise level of the equipment during operation is generally around 70-85 decibels. High-quality equipment will control the noise at a low level through optimized design and noise reduction measures.
Degree of automation
Usually has a high degree of automation, which can realize functions such as automatic control of the switching process of adsorption and desorption, remote monitoring and operation to ensure the stable operation of the equipment and reduce manual intervention.
Continuous operation time
The design can generally meet long-term continuous operation, with a low annual operation failure rate. The annual operation time of some equipment can reach more than 8,000 hours.
Safety performance
The equipment should have good safety performance, such as safety monitoring devices such as safety valves, pressure gauges, temperature sensors, etc. to prevent abnormal conditions such as overpressure and overtemperature; explosion-proof design and fireproof materials are used to ensure safe operation in flammable and explosive environments such as oil and natural gas.

Specific application of NEWTEK PSA oxygen generator in the oil and gas industry
Oil extraction
Improved oil recovery: By injecting high-purity oxygen into the oil layer, the oxidation reaction in the oil layer can be accelerated, the viscosity of crude oil can be reduced, and the crude oil can be more easily extracted, thereby improving the oil recovery rate.
Gas lift oil recovery: The gas produced by the reaction of oxygen with certain components in crude oil is used to increase the pressure in the oil well, lift the crude oil to the ground, and realize gas lift oil recovery.
Natural gas processing
Desulfurization and denitrification: In the process of natural gas desulfurization and denitrification, oxygen can participate in the reaction as an oxidant to oxidize and remove harmful substances such as hydrogen sulfide and sulfur dioxide in natural gas, thereby improving the quality of natural gas.
Catalytic reaction: In some natural gas catalytic conversion processes, an appropriate amount of oxygen is required to participate in the catalytic reaction to improve the reaction efficiency and product quality.
Oil refining
Catalytic cracking: In the catalytic cracking unit, the introduction of an appropriate amount of oxygen can promote the regeneration of the catalyst, improve the activity and service life of the catalyst, thereby ensuring the smooth progress of the catalytic cracking reaction.
Hydrorefining: Oxygen can be used to prepare hydrogen in the hydrorefining process. The oxygen produced by the PSA oxygen equipment reacts with raw materials such as natural gas to generate hydrogen, providing the required hydrogen source for hydrorefining.
