摘　　要：焦炉荒煤气洗苯、富油脱苯是典型流程工艺过程,其工艺结构、能量结构、装备结构形成的运行状态,直接影响工艺过程的能效、洁净度及成本。文章介绍了传统蒸汽脱苯、无蒸汽负压脱苯、蒸汽半负压脱苯三种工艺过程及特点,通过工艺特点、公用工程介质耗量、操作费用、运行成本和投资等多项指标分析比较。无蒸汽富油负压脱苯工艺具有不消耗蒸汽、运行费用低、不产生废水等节能环保的优势,促进了洗脱苯流程工艺过程的高效化、洁净化和有序化运行。The recovery of benzene from COG(coal oven gas),which is composed of wash oil absorption and rich oil distillation,is an important process for COG purification.The process organization,energy consumption,equipment style etc.have a huge impact on the energy efficiency,cleanliness and operating costs of the process.The article introduces three technological processes and characteristics of traditional steam debenzene,non-steam negative pressure debenzene and steam semi-negative pressure debenzene.Through analysis and comparison on process characteristics,utility media consumption,operating costs,operating costs and investment and other indicators,the steam-free and oil-rich negative pressure debenzene process has the advantages of energy saving and environmental protection,such as no steam consumption,low operating cost and no waste water,which promotes the efficient,clean and orderly operation of the benzene elution process.
