摘　　要：Sheer加氢裂化技术是一项能量高效利用的综合技术,包括正常操作停运反应加热炉的加氢裂化专利技术、高温高压逆流传热技术、新型反应器内构件技术、微旋流分离技术、非直接接触在线防垢和除垢技术以及硫化态催化剂新型开工技术。第一代Sheer加氢裂化技术以某加氢裂化装置为基准的计算结果表明,能量转换和传输环节降低能耗2.2%～3.5%;能量利用环节降低能耗0.28%～0.39%;能量回收环节降低能耗7.0%～19.6%。集成开发的第一代Sheer加氢裂化技术可使装置能耗降低9.48%～23.49%,SO2和CO2排放均降低9.48%～23.49%,装置工程投资减少6.32%～12.80%,实现装置低能耗、低投资、长周期运行。Sheer hydrocracking process is a high-efficiency energy-saving process, which includes paten- ted hydrocracking reactor furnace technology with no open fire, HT and HP counter-current heat transfer tech- nology, state-of-art reactor internals technology, micro-swirl separation technology, non-direct-contact fouling prevention technology and new start-up technology for sulfided catalysts. The calculation results of first-genera-tion Sheer hydrocracking process based upon a hydrocracking unit show that, the energy consumption in heat exchange and heat transfer is reduced by 2.2% -3.5% ; the energy requirement in energy utilization is low- ered by 0.28% -0.39% ; the energy consumption in energy recovery is decreased by 7.0% - 19.6%. The application of l st-generation Sheer hydrocracking process can reduce unit energy consumption by 9.48% 23.48% , lower SO2 and CO2 emissions by 9.48% ～ 23.48% and saves 6.32% ～ 12.8% project investment. The unit can be constructed with lower investment and operated reliably at low energy consumption.
