摘 要:减压渣油加工路线的选择影响到炼化企业整体经济效益,通常采用延迟焦化、溶剂脱沥青、固定床渣油加氢、沸腾床加氢等单一加工路线或是其组合加工路线。某大型炼化一体化企业在二期20.0 Mt/a原油加工总流程设计阶段对渣油加工路线进行反复研究对比,确定采用浆态床渣油加氢路线,二期工程顺利投产并高负荷生产,浆态床渣油加氢裂化技术加工减压深拔渣油的先进性和可靠性得到了工业验证,体现了渣油加工技术的重大进展。利用浆态床加氢对重质劣质原料的高适应性,研究提出以溶剂脱沥青、固定床渣油加氢与浆态床加氢的组合工艺对现有渣油加工路线进一步优化,可获得更好的经济效益。The choice of processing route for vacuum residue affects the overall economy of refining enterprises.Usually,delayed coking,solvent deasphalting,fixed bed residue hydrotreating,ebullated bed hydrogenation and other single processing routes or their combination processing routes are adopted.A large-scale refining and petrochemical integration enterprise has repeatedly studied and compared the processing route of residue during the configuration design stage of its 2 nd phase 20 Mt/a crude oil processing complex and determined to adopt the slurry bed hydrocracking route.The second phase of the project was successfully put into operation with high load.The advanced and reliable nature of slurry bed hydrocracking technology for processing deep cut vacuum residue has been verified by such industry application,reflecting the major progress of residue processing technology.By using the high adaptability of slurry bed residue hydrocracking to poor quality heavy inferior feedstock,it is proposed to further optimize the existing residue processing route with the combination of solvent deasphalting,fixed bed residue hydrotreating and slurry bed hydrocracking,which can achieve better economic benefits.
关 键 词:减压渣油 加工路线 浆态床 固定床 加氢裂化 溶剂脱沥青 延迟焦化
