增强型RFS09硫转移助剂在催化裂化装置的工业应用

APPLICATION OF ENHANCED SULFUR TRANSFER AGENT RFS09 IN CATALYTIC CRACKING UNIT

增强型RFS09硫转移助剂(简称硫转移剂)在中国石化镇海炼化分公司3.4 Mt a MIP-CGP催化裂化装置上进行了工业应用。结果表明,当增强型RFS09硫转移剂在反应器-再生器催化剂总藏量中的质量分数达到1.6%后,蓝烟问题基本消除,再生烟气SO_(x)含量下降约80%,脱硫用碱量下降58%,装置降本增效270万元a,且硫转移剂的使用对产品分布、反应器-再生器流化状态和烟机运行情况无不良影响。

The application of sulfur transfer agent RFS09 in the 3.4 Mt a MIP-CGP catalytic cracking unit of SINOPEC Zhenhai Refining&Chemical Company is introduced.It is shown that after the sulfur transfer agent RFS09 content reached 1.6%in the reactor and the regenerator,blue smoke was basically eliminated,SO_(x) content in regeneration flue gas decreased by about 80%,the amount of alkali used for desulfurization decreased by 58%,and the annual cost reduction and efficiency increase reached 2.7 million Yuan.The utilization of sulfur transfer agent has no adverse effects on product distribution,circulation of catalyst between the reactor and the regenerator,and operation of the flue gas turbine.
