【摘要】 利用Aspen Plus軟件,通過普通浮閥塔板代替DJ型塔板對丙烯精餾塔操作進(jìn)行了穩(wěn)態(tài)模擬,對液泛系數(shù)進(jìn)行了76%的修正,得出了不同進(jìn)料量和不同進(jìn)料組成下的優(yōu)化操作條件。結(jié)果表明,在相同進(jìn)料組成下,最優(yōu)回流比及進(jìn)料位置相同;丙烯精餾塔操作優(yōu)化后,x(塔頂丙烯)在99.6%以上,x(塔釜丙烯)在10%以下,分離精度達(dá)到了指標(biāo)要求;406塔與406 A塔位置調(diào)換,可增大裝置操作彈性。
【英文摘要】 The operation of propylene rectification tower was simulated in the stable state by applying Aspen Plus software and using ordinary floating valve tray instead of DJ type tray.Then,the value of flooding coefficient was corrected by 76%and the optimized operating paramerers with different feed amount and different feedstock compostion were obtained.The results showed that the best reflux ratio and feeding position kept invarable for the same feedstock compostion;After the operation optimization of propylene ...
