| 摘 要： | 通过对中国石油化工股份有限公司、中国石油天然气股份有限公司两大公司的70余套催化裂化装置生产数据的分析,发现多数催化裂化装置存在于气中C3 组分含量较高的问题,并提出了解决这一问题的措施.认为通过对催化裂化装置吸收稳定系统的整体优化,采用溴化锂吸收制冷技术,即降低吸收塔操作温度、调整吸收塔操作压力、增加吸收塔和解吸塔的塔盘数等措施,可以有效地降低催化裂化干气中的C3 组分含量,从而增加液化石油气、丙烯的产率.从对中国石油化工股份有限公司的40套催化裂化装置的统计分析看,若采用整体优化措施后,该40套装置总共可以增产98 kt液化石油气和49 kt丙烯,经济效益超过3.5 x108 RMB$.

| Abstract: | The analysis of operation data of 70 FCC units in China Petrochemical Corporation (SINOPEC) and China National Petroleum Corporation (CNPC) has found that most of the FCC units have higher C3+ in dry gas. Effective measures can be taken to reduce C3+ in FCCU dry gas and increase yields of LPG and pro-pylene such as integrated optimization of FCCU and absorption and stabilization system, application of lithium bromate refrigeration technology, lowering absorber operating temperature, adjusting absorber operating pressure and increasing number of column trays of absorber and deasborber. When the integrated optimization is implemented in the 40 FCC units in SINOPEC, additional 98 ,000 tons of LPG and 49,000 tons of propylene can be produced each year and the annual benefit is 350 million Yuan RMB. |
