摘要
对荆门分公司0.8Mt/a DCC-Ⅱ装置吸收-稳定系统解吸塔采用中间再沸器进行改造的情况进行了介绍。解吸塔采用中间再沸器进行改造,结合了冷进料和热进料的优点,可充分利用稳定汽油低温位热量,使塔底再沸器热负荷降低。该项目实施后直接经济效益为233.9万元/a,4个月即可收回全部投资。
The revamping of the desorption tower in absorption-stabilization system of a 0.8 Mt/a DCC-Ⅱ unit in Jingmen Petrochemical Company was reported. A mid-reboiler was added to the desorption tower to combine the advantages of cold feed and heated feed, the heat of the stabilized gasoline could be reused and the heat load of the bottom reboiler was reduced. The economic benefit of the application of mid reboiler technology was 2. 339 MRMB per year, and the investment could be returned in 4 months.
