乌鲁木齐石油化工总厂炼油厂在气体分馏装置改造中应用ＰＲＯ／Ⅱ模拟软件，通过对设备的优化，提高了装置的处理量，改善了产品质量，提高了产率，并节约装置的改造费用。改造中保持原乙烷塔径１ｍ不变，由浮阀塔板改用 ＤＪ型筛孔塔板，节约新建脱乙烷塔费用 ２０ Ｘ１０~４ ＲＭＢ￥；新建丙烯塔采用 ３台表面蒸发式空冷与同处理量采用４台湿式空冷和２台后冷相比，传热面积提高了３０％，能耗降低２５％，年节约操作费用６４％；装置改造后丙烯产率达３３．０６％，比改造前提高约１６个百分点，精丙烯纯度９９．６％，达到国家优级品标准。
The Refinery of Urumqi Petrochemical Complex applies PRO / Ⅱ simulation software in the reform of the gas fractionation plant. Through the optimization of the equipment, the throughput of the plant is increased, the product quality is improved, the yield is increased, and the cost of the device reforming is saved. Retrofitting to maintain the original ethane tower diameter 1m unchanged from the valve tray to DJ type sieve tray, save the cost of new de-ethane tower 20 X10 ~ 4 RMB ¥; the new propylene tower using three surface-evaporative air-cooled Compared with the same treatment capacity of 4 sets of wet air cooling and 2 sets of after cooling, heat transfer area increased by 30%, energy consumption decreased by 25%, the annual operating cost savings of 64%; propylene production rate of 33.06% About 16 percentage points higher than that before the transformation, and the purity of fine propylene reaches 99.6%, reaching the national standard of excellent products.
