国内外常减压蒸馏工程技术浅析

对国外炼油厂15.00 Mt/a常压蒸馏装置、20.00 Mt/a常减压蒸馏装置和国内某炼油厂10.00 Mt/a常减压蒸馏装置加工原油、生产方案、加工流程、操作条件、设备选择及能量消耗等方面进行了对比。结果表明，3套装置各有技术特点，国内装置的能耗为387.3 MJ/t原油，远低于国外炼油厂装置的能耗。

BRIEF ANALYSIS FOR ATMOSPHERIC AND VACUUM DISTILLATION TECHNOLOGY AT HOME AND ABROAD

With the development of the atmospheric and vacuum distillation technology, a considerable progresses in process flow, mass and heat transfer, energy-saving and friendly environment are achieved. Three crude distillation units with different capacities at home and abroad are quoted as cases in this paper. The crude properties, product scheme, process flow and operating parameters are introduced in detail, while their equipment selection and engineering expertise are emphasized. The brief analysis is performed on their utility summary and energy consumption. The comparison and analysis conclude that the three sets of distillations have different characteristics. However, the energy consumption（387.3 MJ/t）of the domestic refinery is far lower than the foreign refineries.
