Research and design of energy saving and consumption reduction scheme for waste heat utilization in oil and gas treatment station
In the process of three-phase separation of crude oil in oil and gas treatment station,the produced liquid is heated and raised in temperature,and the separated high-temperature produced water is directly reinjected into the formation,resulting in heat waste and softening,deformation and leakage of the reinjection pipeline.Aiming at the waste heat utilization of oil and gas treatment station,the applicability of different heat pumps and heat exchangers is evaluated,and the feasibility of three schemes:Direct heat exchange,heat pump temperature raising and heat exchange+heat pump temperature raising is studied.The results show that the absorption heat pump is suitable for medium and high temperature heat consumption,and the price of natural gas or steam is relatively low.The plate heat exchanger has high heat transfer coefficient and high viscosity working medium.The heat exchange+heat pump temperature raising scheme has moderate investment cost,maximum gas saving and good investment return rate,and is suitable for waste heat utilization projects in oil and gas treatment stations.
