常减压装置减压深拔技术的应用

Application of Pressure Reducing Technology in Atmospheric and Vacuum Distillation Unit

随着经济的发展,能源日趋紧张,石油资源逐渐枯竭,炼油厂走原油深加工路线成为必然的选择,因此通过常减压装置减压深拔技术,提高原油拔出深度,从渣油中挖取更多的效益,对提高目前炼油厂的经济效益具有十分重要的意义。减压深拔,是把原油切割到560℃以上,并使所拔出的重质蜡油的质量满足加氢裂化类装置对原料质量的要求,同时减压渣油中<500℃的轻组分含量不超过5%。

With the development of economy, energy is becoming more and more tense, oil resources are gradually depleted,refineries go deep processing route of crude oil becomes the inevitable choice.Therefore, through deep decompression and deep drawingtechnology, the depth of crude oil extraction is improved, Dug more benefits, to improve the current economic benefits of the refineryis of great significance.Decompression and deep drawing, the crude oil is cut to 560 ℃ or more, and the quality of the stripped heavywax oil to meet the hydroeracking type of raw material requirements, while the vacuum residue 〈500 ℃ light group The content of notmore than 5%.
