Effect of Molecular Sieve Dehydration Technology on Product Quality of C_(5)/C_(6) Isomerization Unit and Countermeasures

分子筛吸附脱水是C_(5)/C_(6)异构化装置常用脱水方法之一,原料脱水效果的好坏对异构化装置的正常操作和产品质量有十分重要的影响。以某厂190 kt·a^(-1)半再生重整装置工艺技改为C_(5)/C_(6)异构化装置为例,针对分子筛脱水技术对异构化装置产品质量的影响及对策进行了阐述,通过对分子筛脱水系统进行技术改造,解决了反应进料水含量高的实际生产难题,改善了催化剂的使用效果,提高了异构化产品的辛烷值。

Molecular sieve adsorption is one of the common dehydration methods of C_(5)/C_(6)isomerization unit.The effect of raw material dehydration is of great significance to the normal operation of the isomerization unit and the product quality.In this paper,the effect of the molecular sieve dehydration technology on isomerization unit product quality was introduced with 190 kt·a^(-1)semi-regeneration reforming unit transformed C_(5)/C_(6)isomerization unit as an example.With the technical revamping of molecular sieve dehydration system,the actual production problem of high feed water mass fraction was solved,the performance of catalyst was improved,and the octane value of isomerization products was improved.
