摘要
随着环境保护要求的日益严格,国家对柴油质量的要求也越来越高。中国石油化工股份有限公司燕山分公司加氢裂化装置进行了掺炼催化裂化(FCC)柴油的尝试。结果表明,通过将一定比例的FCC柴油掺入到加氢裂化装置进行加工处理,低十六烷值的FCC柴油除部分转化为石脑油、航煤等轻质产品外,所得产品柴油仍能满足北京市地方标准,为FCC柴油的加工处理手段进行了有益探索。但掺炼加工FCC柴油比例不宜过大,因为掺入FCC柴油后会造成装置冷氢用量增加、氢气消耗量增加,且航煤、柴油及尾油质量都会受到不同程度的影响。
With the increasingly strict demand on environment protection, the State＇ s requirements on diesel quality are becoming higher. The hydrocracking plant of SINOPEC Yanshan Company made trial on blending inferior FCC diesel into the plant for processing. Result showed that excepting part of the FCC diesel with low cetane number was converted into light oil products as naphtha and jet fuel ,the diesel product still could meet Beijing local standard,which made a good exploration for processing measures of FCC diesel. However, the proportion of inferior FCC diesel should not be too high, for it might cause increasing of cold hydrogen and hydrogen gas consumption, and affect the quality of jet fuel, diesel and tail oil to different extent.
