Residual pressure energy recovery
Thread Content
Gentlemen! Our facility has gas that is released under a pressure of 4 kilograms, with a flow rate of 2000 m3/h. It seems wasteful to let the residual pressure of this gas be released without being recovered; does anyone have any experience or insights regarding energy recovery solutions?
The reason for the existence of excess pressure relief at the source should be addressed Such phenomena usually do not occur in well-designed systems. Finally, the causes of the residual pressure are clarified to facilitate discussion and for reference.
Vent gas is the exhaust gas generated during production, so this residual pressure wants to be recovered.
Kinetic energy can generate electricity. Is the composition of residual gas useful?
Systems similar to TRT power generation can be developed; the key factor is the volume of gas available, which determines the scale of the units that need to be installed
Your capacity is relatively small, so the work done through expansion is not high – around 80 kilowatts. If you look into expanders, they can be used to drive water pumps or compressors; using them for power generation would be rather inefficient
