摘　　要：介绍大连西太平洋石油化工有限公司 2 .0Mt/a重油催化裂化装置主分馏塔的极限负荷试验情况。该分馏塔塔径 6 40 0mm ,内置 30层双溢流筛孔塔板。试验结果表明 ,该塔的负荷极限为 2 .47Mt/a ,欲将装置处理量提高至 2 .8Mt/a ,需将现有筛板更换为高性能塔板或填料。实际生产中 ,换热段塔板的操作上限可超出计算上限 ,而精馏段塔板的操作上限低于计算上限 。The limit test of processing capacity of the main fractionator of 200 000 0t/yr RFCCU in Dalian West Pacific Petrochemical Company was introduced.The main fractionator has a diameter of 6400 mm and 30 double flooding sieve trays.The results showed that its maximum processing capacity is 247 000 0 t/yr.To raise the capacity up to 280 000 0 t/yr,the sieve trays must be replaced by high efficiency trays or packings.In practical operation,the operation uplimit of trays in heat transfer zone can surpass the calculating uplimt,while the operation uplimt of trays in fractionating zone is lower than the calculating uplimit.
