轻石脑油异构化开车过程除去氧化物的措施
|
摘要
C_5/C_6正构烷烃异构化是提高汽油辛烷值最经济有效的方法之一,生成的异构化油具有无烯烃、无芳烃、无硫、无苯等特点,是汽油调合的理想组分。巴基斯坦国家炼油公司的异构化装置采用UOP公司提供的Penex工艺。异构化反应器装填的I-84催化剂是整个装置的核心。该催化剂对含氧化合物十分敏感。因此开车过程中如何除去系统中的氧气、水和铁锈是装置开车成功的关键。介绍了该项目C_5/C_6异构化装置在开车过程中采取的措施。
The isomerization of normal C_5/C_6 hydrocarbons is one of effective and economic ways to ele-vate the octane number of gasoline. The isomerate,which is free from olefins,aromatics,sulfur and benzene,is the satisfactory blending component of gasoline. In isomerization project of Pakistan National Oil Company,UOP's Penex process has been selected. The isomerization reactor bed is loaded with I-84 catalysts. This cat-alyst is very sensitive to the materials containing oxides. Therefore,the removing of oxygen,water and rustsfrom the system during the start-up is very critical for the success. The effective measures taken for the suc-cessful start-up of a C_5/C_6 isomerization unit are introduced.
