摘要:
利用Aspen HYSYS软件对轻汽油醚化装置预加氢单元的轻重汽油分离系统进行模拟计算，从操作条件、产品质量、设备情况、公用工程消耗等方面对3种分离方案进行对比。结果表明：汽提塔和分馏塔方案流程较复杂，产品质量较优，设备投资较大，但能耗较小；分馏塔-塔顶产出产品方案，流程简单，设备投资和能耗均较小，但轻汽油产品初馏点较低，易对下游醚化单元操作造成不利影响；分馏塔-侧线产出产品方案，产品质量最优，但设备投资和能耗较大。
Abstract:
The gasoline separation system in a prehydrogenation unit of a light gasoline etherification unit was simulated and calculated by Aspen HYSYS software. Three common separation schemes were compared in terms of operating conditions， product quality， equipment conditions and general utility consumption. The results showed that the stripper and fractionator scheme′s process was relatively complex， but with better product quality， higher equipment investment，but less energy consumption. The scheme in which products comes out from the top of the fractionation tower had a simple process， small equipment investment and energy consumption， but the initial distillate point of light gasoline products was low， which was easy to cause adverse effects on the downstream etherification unit operation. The solution of product output from fractionating tower-side line output had the best product quality， but the equipment investment and energy consumption were high.
