【摘要】：利用大型化工模擬軟件Aspen plus對工業(yè)雙戊烯連續(xù)真空精餾過程進(jìn)行模擬�？疾炝诉M(jìn)料位置、回流比、塔頂采出率及塔頂壓力對檸檬烯純度及再沸器能耗的影響,得到了雙戊烯精餾的最佳條件為:理論塔板數(shù)為65,進(jìn)料位置在第30塊塔板處,回流比4∶1,進(jìn)料量1 000 kg/h,進(jìn)料溫度100℃,塔頂采出率為0.7,塔頂壓力5 k Pa,塔壓降12 k Pa。經(jīng)生產(chǎn)實(shí)踐驗(yàn)證,可以得到純度為71.5%的檸檬烯,與模擬數(shù)據(jù)(72.43%)偏差較小。
[Abstract]:The continuous vacuum distillation process of industrial dipentene was simulated by large scale chemical simulation software Aspen plus. The effects of feed position, reflux ratio, top recovery rate and top pressure on the purity of limonene and energy consumption of reboiler were investigated. The optimum conditions for distillation of dipentene were as follows: theoretical tray number was 65, feed position was at the 30th tray, Reflux ratio 4: 1, feed rate 1 000 kg/h, feed temperature 100 鈩，
