摘要:
利用英国KBC公司开发的Petro-Sim流程模拟软件建立了常减压联合装置的机理模型，模拟优化了300万t/a常减压装置生产道路沥青的最佳生产操作条件。结果表明：通过提高常压塔塔底汽提蒸汽注入量，优化减压塔中段回流取热，可提高常减压装置的物料分离精度。经模拟优化后，当常压炉出口温度由358.0 ℃降低至347.0 ℃时，减压炉出口温度由375.0 ℃升高至398.0 ℃，使部分常压炉负荷转移至减压炉，不仅致使该常减压装置马瑞原油加工量由272.30 t/h提高至357.60 t/h，达到原设计加工量要求；而且产物中的石脑油、混合柴油、道路沥青产量依次增加了31.01%，51.21%，30.52%，尽管混合蜡油产量变化不大，但使该联合装置综合经济效益增收447.9万元/月。
Abstract:
The mechanism model of atmospheric and vacuum distillation unit was established by using Petro-Sim process simulation software developed by KBC Company in Britain. Then the optimum operating conditions of the combined 3.0 Mt/a atmospheric and vacuum distillation unit was simulated and optimized during producing road asphalt. The results showed that the material separation accuracy of this combined atmospheric and vacuum distillation unit could be improved by increasing the stripping steam injection capacity at the bottom of the atmospheric tower and optimizing the heat recovery by reflux in the middle section of the vacuum tower. After the simulation and optimization，when the outlet temperature of atmospheric furnace reduced from 358.0 ℃ to 347.0 ℃，the outlet temperature of vacuum furnace increased from 375.0 ℃ to 398.0 ℃，which transferred part of the processing load of atmospheric furnace to that of vacuum furnace. In this way，not only caused the actual processing capacity of Merey crude oil in this combined unit increase from 272.30 t/h to 357.60 t/h，which reached the original designed processing capacity requirements，but also the yield of naphtha，mixed diesel oil and road asphalt in the products increased by 31.01%，51.21% and 30.52% in turn，however the yield of mixed wax oil changed little，but the comprehensive economic benefit of this combined unit increased by 4.479 million yuan per month.
