Abstract—In changing the composition of coking batch, it is expedient also to ensure effective operation of the benzene department, both in terms of the production of commercial phenolic hydrocarbons and in order to maintain normal operation of the coke batteries’ heating system. In assessing the fresh absorbent oil used to replenish the circulating oil, not only its operational characteristics must be taken into account but also its influence on the performance of the absorbent already in the system. The introduction of low-molecular components in the circulating absorbent oil intensifies the extraction of hydrogen sulfide from the coke-oven gas in the benzene department. In selecting the composition and properties of the circulating absorbent oil, the operation of the specific benzene system and the overall gas channel must be taken into account.

摘要-在改变焦化批料的组成时，还应确保苯部门的有效运行，无论是在生产商业酚类烃方面，还是在保持焦炭电池加热系统正常运行方面。在评估用于补充循环油的新鲜吸收剂油时，不仅必须考虑其操作特性，而且还应考虑其对系统中已有吸收剂性能的影响。在循环吸收油中引入低分子成分，可增强苯部门从焦炉煤气中提取硫化氢的能力。在选择循环吸收油的成分和性能时，必须考虑特定苯系统的操作和整个气体通道。
