In this paper,in view of the problem of vacuum tail gas treatment in the process of waste mineral oil production,three kinds of vacuum tail gas purification technology of vacuum distillation of mineral oil are discussed.These technologies cover processes such as negative pressure liquid absorption,freezing liquefaction,pressure liquefaction and low pressure liquid absorption.Through practical application,these technologies have effectively solved the difficult process environmental problems of vacuum tail gas treatment,and improved the production yield and environmental protection level.
