直馏柴油脱酸工艺研究进展

RESEARCH AND DEVELOPMENT ON THE PROCESSES OF REMOVING NAPHTHENIC ACIDS FROM STRAIGHT-RUN DIESEL OIL

摘要: 综述了直馏柴油脱酸方法的发展。氯法化学萃取是目前直馏柴油脱酸工艺的研究热点，能否取代直馏柴油碱洗电精制一硫酸中和法工艺，其关键在于新型破乳剂、高效率萃取设备和三相分离器的开发。介绍了作者开发的SW－1破乳剂在直馏柴油氯精制工艺中的应用研究。

Abstract: This paper reviews the processes of removing naphthenic acids from straight-run diesel oil.The study hotspot of removing naphthenic acids techniques for straight-run diesel oil is chemical extraction by ammonia method.Whether or not it replaces the proces
