Jet pump systems
One of the main directions of improvement of technical procedure for the natural gas processing is the development and adoption of energy-saving technologies, allowing full utilization of energy reserves of the oil and gas industry. Such reserves include:
Jet compressors (Jet pumps) in natural gas processing and treatment field systems are the most effective way of such energy resources usage. In such a case, the excess pressure of high-pressure gases is used in jet pumps for low-pressure gases compression and for feeding them into the gas gathering and processing field system.
Low-pressure gas ejecting process can be described as follows: high-pressure gas flow is passing under high pressure and at high velocity through the supersonic nozzle, creating a low pressure area in the mixing chamber of jet pump. Since the pressure in this area is lower than the pressure of low-pressure gas, low-pressure gas flows into the mixing chamber of jet pump. Low-pressure gas suction depends on the degree of rarefaction in the mixing chamber. In the mixing chamber of the jet pump the high-pressure flow mixes with the low-pressure flow, forming the mixed flow. From the mixing chamber, the mixed flow enters the diffuser where it is decelerated and gas static pressure is increased. The pressure of the mixed flow at the outlet of jet pump exceeds the pressure of low-pressure gas.
The pressure of low-pressure gas increases without the mechanical energy consumption. Thus, the use of jet pump technology in the oil and gas industry provides more robust and reliable technical solutions compared to mechanical blowers (compressors, gas blowers, fans, etc.).
"AEROGAS" company created a jet pump system with unique characteristics for sustainable compression of liberation gas, for lifetime extension of depleted gas wells, etc. Jet pumps types: single-stage, multi-stage, multijet and special design. Each of jet pumps is custom-designed depends on specific operating conditions at Customer’s field.
These jet pump systems can be easily integrated into the standard manifolds of inlet wells.
