一、简介(一)吸收系统解吸塔工艺流程图1为我公司第三联合车间催化装置稳定系统解吸塔工艺流程。自凝缩油罐D-2301来的凝缩油经P-2301加压后,与稳定汽油换热(E-2305)到70℃,进入解吸塔C-2302上部,塔底温度110~130℃,塔顶压力1.5~1.6MPa(绝),解吸塔底重沸器由分馏塔一中回流和低压蒸汽供热,解吸塔顶气体至EC-2301之前与压缩富气混合进入D-2301。
I. Introduction (A) Absorption system desorption tower process flow chart 1 for my company’s third joint workshop catalytic plant stabilization system desorption tower process. The condensate from self-condensing tank D-2301 is pressurized by P-2301 and heats with stabilized gasoline (E-2305) to 70 ° C and enters the top of desorption column C-2302 with a bottom temperature of 110 to 130 ° C , The pressure at the top of the column is 1.5 ~ 1.6MPa (abs.). The desorption tower bottom reboiler is heated by the first reflux and the low pressure steam in the fractionation tower and is mixed with the compressed rich gas into the D-2301 before desorbing the overhead gas to the EC-2301.
