【摘要】：FCC轻汽油醚化工艺是当前技术较为成熟的工艺,国内外都广泛使用,尤其是在环保要求日益严峻的今天,其生产的醚化产品可有效降低汽油中的烯烃含量,提升车用汽油的质量,在有效降低汽车尾气中污染物排放的同时,提升汽油辛烷值。探索汽油醚化装置长周期运行的可行方案,对醚化汽油的生产具有一定的现实意义,本论文主要通过对比国内外现有催化轻汽油醚化工艺,了解当今的轻汽油醚化工艺技术水平,通过对兰州石化公司炼油厂50万吨/年汽油醚化装置运行近三年的数据进行收集、分析、研究,探索制约装置长周期运行的因素,使装置更长久稳定的运行,根据实际生产操作中催化剂性质、醚化反应机理、原料性质、水、工艺操作参数等的不断探究及优化,试图化解各影响因素造成的不利影响,使装置实现长周期平稳运行。
[Abstract]:The etherification process of FCC light gasoline is a mature technology, which is widely used at home and abroad, especially in the increasingly severe environmental requirements today, its etherification products can effectively reduce the olefin content in gasoline. Improve the quality of vehicle gasoline, effectively reduce the emission of pollutants in vehicle exhaust, and improve the octane number of gasoline at the same time. It is of practical significance for the production of etherified gasoline to explore the feasible scheme of long period operation of gasoline etherification unit. This paper mainly compares the existing catalytic light gasoline etherification process at home and abroad. To understand the present technology level of light gasoline etherification, through collecting, analyzing, researching and exploring the factors restricting the long period operation of 500000 t / a gasoline etherification unit in Lanzhou Petrochemical Company Refinery, through collecting, analyzing, studying and exploring the factors restricting the long period operation of the unit. According to the characteristics of catalyst, etherification reaction mechanism, raw material property, water, process operation parameters and so on in the actual production operation, the unit can be operated more and more steadily and continuously, in order to resolve the adverse effects caused by various influencing factors. The device can run smoothly for a long period.
