摘要:

从2007年到2015年,IHCC工艺历经工艺研究、过程开发和工业试验,完成了一系列中小型探索试验、基础设计、工程设计、关键设备开发、工业装置的建设与开工、工业试验方案制定与标定等研究工作。工业试验结果表明:对于加氢重油原料,相对于FCC工艺,IHCC工艺的液体产品收率增加了10.04百分点,焦炭产率下降了20%以上;对于石蜡基常压渣油原料,相对于FCC工艺,IHCC工艺的液体产品收率增加了6百分点以上。IHCC工艺的成功开发标志着炼油技术从追求高转化率向追求高选择性转变,从而实现石油资源的高效利用,同时还将部分解决中国石油化工能效倍增与二氧化碳排放问题。

Abstract:

From 2007 to 2015, IHCC process (Integration of FCC Gas Oil Hydrotreating and Highly Selective Catalytic Cracking for Maximizing Liquid Yield), after process development and industrial test, completed a series of technical consideration, pilot plant experiments, basic and engineering design, key equipment development, as well as construction and start-up of industrial unit, industrial test plan formulation and calibration work. The commercial tests of IHCC disclose that compared with conventional FCC process, the liquid yield can be increased by 10.04 percentage points and coke yield decreased by over 20% , respectively using hydrotreated residue as feedstock, while liquid yield can be increased by 6 percentage points using paraffinic AR feed. The successful development of IHCC technology shift the refining technology from pursuing high conversion to high selectivity, leading to efficient utilization of oil resources, and reduction of CO2 emission and energy saving for SINOPEC.
