基于制冷技术的油气回收过程

Oil Vapor Recovery Process Based on Refrigeration Technology

经对几种主要油气回收方法的简单比较,介绍了直接冷凝法,它不仅可达到国家排放标准,而且在低温下操作,安全性好,在适当规模下运行时,经济效益较好,是目前世界各国优先选用的方法。为避免-100℃深冷,能耗过大,还介绍了预冷凝-膜分离和冷凝-吸附组合工艺。

In the course of storage and distribution of oil products, there is large amount of evaporation loss, which not only cause energy waste, but also bring about environment pollution. Oil vapor recovery is the most effective method to solve the problem. The principle of oil vapor recovery based on direct refrigeration and the application of combination process on oil vapor recovery were introduced.
