1.4Mt/a重油催化裂化装置能耗分析与措施

青岛石化1.4Mt/a重油催化裂化装置的能耗占到了公司总能耗的40%多,其中烧焦能耗在催化总能耗中占相当大的比例,因此采取措施降低生焦率成为降低装置能耗的关键所在。另外,将主风机降至最低耗功状态运行也是一项降低电耗的有效措施。装置节能降耗工作主要从两方面入手,一是通过优化工艺操作条件,降低生焦率、电耗和蒸汽消耗,尽量减少能耗;二是通过技术改造提高装置用能水平。经过几次改造后,2008年装置能耗为63.3kg标油/t原料,并且实现连续两年达标。但仍然存在烟气能量回收系统效率不高、气压机负荷高、生焦率较高、热联合不足等问题。下一步应在加工含酸原油项目改造后,对催化装置操作条件进行调整;对主风机运行效率进行核算,调整运行参数使功耗最低;将反应压力控制改为气压机转速调节;利用流程模拟软件建立装置模型,找出最佳操作参数。

Energy Consumption Analysis for 1.4Mt/a RFCC Unit and Optimization

SINOPEC Qingdao Petrochemical Company's 1.4Mt/a RFCC unit represents more than 40% of the company's total energy consumption and energy consumption in coke burning accounts for a large proportion of the total energy consumption in the catalytic process.Therefore,reducing the generation of coke is the key to reducing the energy consumption of the unit.In addition,running the main fan at its lowest power consumption state is another effective method of reducing electricity consumption.There're two main approa...
