| Abstract: | The methanol-bearing wastewater from Changqing gas field were associated with varied concentration, serious scaling potential, and high energy consumption. In this paper, combining with the relative volatility of methanol and water, theoretical simulation were conducted on atmospheric distillation, vacuum distillation, and heat pump distillation. The results revealed that the application of heat pump distillation for methanol recovery in the gas field could achieve the purpose of energy-saving and cleaner production. |
