摘要
利用炼油厂现有装置优化组合，可为催化裂化装置及乙烯装置提供更多的优质原料，以提高炼油厂经济效益。介绍了为此目的开发的几种渣油轻质化的组合工艺。
By optimally combining the existing processing units in refineries, it is possible to provide morequalified feedstocks for FCCU and ethylene units to enhance economic benefits of the refineries. Several combi-nation processes developed for residue upgrading were introduced.
