由洛阳石化工程公司、安庆石化总厂和济南炼油厂共同承担的国家“八五”科技攻关项目“催化裂化-芳烃抽提组合工艺(ICAE)”,已达到预定目标,于1995年9月6～7日在安庆石化总厂通过了中国石化总公司发展部主持的技术鉴定。 该工艺通过脱除催化裂化重油中的重质芳烃(抽出油),使饱和烃组分(抽余油)与新鲜进料混合返回装置,以改善进料质量,提高工艺性能。 由于ICAE工艺从催化裂化系统取出了只能在反应过程中生成大量焦炭而难于裂化成轻质烃的重质芳烃,故该工艺可大幅度地提高装置处理能力;与此同时,抽余油的返回提高了催化裂化
The national “Eighth Five-Year Plan” scientific and technological project “Combustion-Aromatics Extraction Combining Process (ICAE)” jointly undertaken by Luoyang Petrochemical Engineering Company, Anqing Petrochemical Plant and Jinan Refinery has reached the scheduled target. Since September 6, 1995, ~ 7 in Anqing Petrochemical Plant adopted the development of China Petrochemical Corporation presided over the technical appraisal. The process is to remove the heavy aromatics (extracted oil) from the catalytic cracking heavy oil, and to mix the saturated hydrocarbon components (raffinate oil) with the fresh feed back to the device to improve the feed quality and improve the process performance. Because the ICAE process removes heavy aromatics from the FCC system that generate only a significant amount of coke during the reaction and are difficult to crack into light hydrocarbons, the process significantly improves plant throughput; at the same time, Return improves catalytic cracking
