Energy is an essential factor for developing social progress and human society. As a matter of fact, the energy conservation and emission reduction has become a consensus as it is facing social and environmental problems induced by increasing energy consumptions. As a significant component of energy technology, the low grade waste heat recovery technique has a great potential. In the process of production and processing of natural gas treatment plant, a large amount of waste heat will be generated due to boosting. Normally waste heat is directly cooled, which wastes enormous energy. In response to the national policy of energy saving and emission reduction, we aim at the analysis of the waste heat produced in the plant and the heat users, and analyze the various utilization means of waste heat such as heating, auxiliary production in the plant area, winter heating in the living area, waste heat refrigeration and waste heat power generation one by one, obtaining the best way for waste heat utilization. In the course of engineering, optimizing waste heat using strategy scientifically and effectively will not only make profit to the plant enterprise but save energy consumption.
