Techniques for the Utilization of the Waste Heat of Gas Field Booster Sets

There are 3 available routes for the utilization of the waste heat of flue gas from gas field booster sets, i.e., heat, electricity and mechanics. A review is conducted on the research and current trends in the techniques concerning the application of flue gas waste heat, which include direct recycling of heat energy, absorption refrigeration, Organic Rankine Cycle and thermal energy conversion. Combined with the practice in gas field exploitation, the potential and development of all waste heat application techniques of boosters are analyzed and discussed. All the current conditions of gas field booster sets, the performance of these sets as well as the operational modes should be taken into consideration when scheming for waste heat application.
