CRI乙苯脱氢催化剂的应用

The Long-period Operation of CRI Ethylbenzen-dehydrogenated Catalyst

CR I公司的Flexicat yellow/blue催化剂是大庆石化苯乙烯装置应用的第四批乙苯脱氢催化剂,在延长期采取了合理提高入口温度、合理匹配稀释蒸汽的用量、加强尾气压缩机的操作等有效的操作方法,使该催化剂从装填到卸载共运行了35个月,共生产苯乙烯210913吨,使用周期增加46%,增加经济效益1.5亿元。该催化剂的运行周期创造了大庆石化苯乙烯装置乙苯脱氢催化剂运行时间最长的纪录。同时该催化剂在运行期间的各项指标都达到历史最好水平。

Flexicat yellow/blue catalyst produced by CRI was the fourth dehydrogenization catalyst which was used in Daqing 60KTA styrene equipment. We have taken effective ways and means to prolong the validity-period of the catalyst, including improving in-let temperature, adjusting the radio of steam/ethylbenzen, optimizing the operation of compressor etc. The catalyst has run 35 months, 46% longer than anticipated. The total production of styrene was 210913 MT. More than 150 million RMB was gained. It has created the longest and the best record of Daqing 60KTA styrene equipment dehydrogenization-catalyst.
