年处理量110万吨催化裂化装置工艺设计 摘要 随着我国经济的快速发展，我国对能源的需求量急剧增加和对环境问题越发关注。特别是对汽油等轻质油特别是高质量的清洁能源的需求量剧增。而随着炼油工业的不断发展，催化裂化日益成为石油深度加工的重要手段，在炼油工业中占有举足轻重的地位。将重质油更多地转化成轻质油品，且转化成清洁能源是催化裂化的重要课题。催化裂化是原油二次加工中最重要的加工过程，是在热和催化剂的作用下使重质油发生裂化反应，转变为液化石油气、汽油、柴油等过程。 本设计加工弹性大，汽油产率较高，采用多产液化气和汽油工艺技术,进行了技术分析工艺流程主要设备工艺计算等Abstract With the rapid development of our economy, our countrys energy demand of environmental problems dramatically increased and more attention. Especially for gasoline, etc; especially high quality demand for clean energy to rising dramatically. With the continuous development of oil refining industry, the FCC has increasingly become an important means of oil deep processing, oil refining industry in plays a very important role. Will heavy oil more into light oil, and into clean energy is an important subject of catalytic cracking. The FCC is the most important second processing of crude oil in the process, is under the action of heat and catalyst that heavy oil, change the cracking reaction happened for liquefied petroleum gas, gasoline, diesel oil and other process. This design machining flexibility, gasoline production rate is higher, adopt prolific liquefied gas and gasoline technology, through technical analysis, process design, the main equipment process calculation and process chart drawing, etc., and has fully considered the comprehensive utilization of energy and protecting the environment problems.
