摘要
在柴油质量升级为国Ⅲ或国Ⅲ以上标准后,催化裂化柴油都必须经过加氢处理。WEPEC对柴油池组分及催化裂化柴油可利用的加工路线进行了分析,结果表明,对于采用的加工流程配置,催化柴油经柴油加氢装置处理后,其氢耗、能耗和加工费分别低于加氢裂化装置129m3/t、12.5×104 kJ/t和47.9元/t。因此,柴油加氢装置在确保反应器床层不超温的情况下,最大量的掺炼催化柴油是WEPEC首选的经济性途径。
After the diesel quality upgrading to the national standard of grade III or superior to grade III, hydrogenation processing is necessary for FCC diesel of WEPEC. By analyzing the compo- nents of the diesel pool and selecting the available processing route of WEPEC, the results showed that the hydrogen consumption, energy consumption and processing costs of the process configuration were lower than those of the hydrocracking unit in 129 m3/t, 12.5 × 104 kJ/t and RMB 47.9 yuan/t u- nits after the hydroprocessing of the diesel oil. Therefore, in the premise of avoiding over-temperature of the reactor bed, the most economic route of WEPEC is to blend FCC diesel oil as much as possible.
