中文摘要：随着哈国库姆科尔原油的减产，哈萨克斯坦PKOP奇姆肯特炼油厂将改炼西哈混合原油，由于新的混合原油偏重，给PK炼厂现有各装置的加工负荷、产品分布、全厂平衡等带来了一系列的影响。西哈混合原油，由于其石脑油馏分少，影响了催化重整的装置进料，进而影响到全厂氢气平衡；西哈混合原油的重质馏分更多，金属含量高，为适应新原油，炼厂需调整全厂加工方案，增开减压蒸馏装置以改善催化原料条件。此外，炼厂现有的减压蒸馏、柴油加氢装置需要进行相应的改造以提高全厂加工西哈混合原油的适应性。
英文摘要：With the reduction of Kumkor crude oil in Kazakhstan, the PKOP Chimkent refinery in Kazakhstan will be converted into West Kazakh crude oil. Due to the weight of the new crude oil, the processing load and product distribution of the existing equipment of the PK refinery will be given. , Plant-wide balance, etc. brought a series of effects. Xiha mixed crude oil, because of its low naphtha fraction, affects the feed of the catalytic reforming unit, which in turn affects the hydrogen balance of the whole plant; Xiha mixed crude oil has more heavy fractions and high metal content, in order to adapt to the new crude oil The refinery needs to adjust the processing plan of the whole plant and add a vacuum distillation device to improve the conditions of the catalytic raw materials. In addition, the existing vacuum distillation and diesel hydrogenation units of the refinery need to be modified accordingly to improve the adaptability of the whole plant to process Siha blended crude oil.
