摘　　要：对利用一种新型立板式隔板精馏塔切割直馏汽油工艺进行了研究。首先,利用模拟软件HYSYS对该分离过程进行模拟,得到较优的工艺条件。在此基础上,利用立板式隔板塔实验装置,考察了塔顶总回流量、液体分配比等操作参数对产品的影响及装置的操作稳定性。结果表明,塔顶总回流量的增大有助于产品的分离,且液体分配比的选择范围更广。液体分配比的改变对中间侧线产品质量的影响较大,是操作的关键变量。Straight-run gasoline separation was studied with a novel column structure, the dividing wall column. This process was simulated with a commercial software HYSYS, and then the optimized design parameters were obtained. Based on these parameters, operation conditions such as the reflux ratio and the liquid split ratio were investigated with a pilot plant. Experimental results revealed that a higher reflux ratio is beneficial to the product separation, while the energy consumption is relatively higher. Also, the liquid split ratio has a wider range for selection, which is an important factor for the product quality.
