摘要
针对长庆气田含醇污水浓度变化范围大、结垢严重、能耗高等运行现状,结合甲醇与水的相对挥发度,理论模拟分析了常压精馏、减压真空精馏、热泵减压真空精馏3种工艺,分析得出热泵减压真空精馏法应用在气田甲醇回收领域不仅节能降耗且能实现清洁生产。
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.
