粗汽油和精制油制氢技术在连续重整装置开工中的应用

对连续重整装置开工用氢气来源、粗汽油和精制油制氢原理及流程、制氢投资情况等进行了讨论,并结合两套新建60×104 t/a连续重整装置的制氢装置,对比分析了两种开工制氢方案。得出如下结论:若氢气来源较为困难,连续重整装置开工时可考虑增加1套粗汽油或精制油制氢装置;精制油制氢方案适用于精制油储备充足的工厂,在精制油不足的情况下宜优先考虑采用粗汽油制氢的方案;催化剂在制氢装置投资费用中所占比例较高,约为67.48%。

Application of hydrogen-producing technology using naphtha or refined naphtha in the start-up of continuous catalyst reforming unit

The source of hydrogen for the start-up of continuous catalyst reforming unit, mechanism and process flow of hydrogen-producing technology using naphtha or refined naphtha, investment of hydrogen-producing technology etc. were discussed. Combined with the start-up of two sets newly built hydrogen production device of 600×10³ t/a continuous catalyst reforming unit, the two kinds of start-up hydrogen-producing scheme were compared and analyzed. Conclusions are drawn as follows:If the start-up hydrogen is difficult to get, a set of hydrogen-producing device for unit start-up using naphtha or refined naphtha may be increased. Hydrogen-producing device using refined naphtha is suitable for the refinery with enough refined naphtha. Otherwise, hydrogen-producing device using naphtha should be preferentially considered. The catalyst cost accounts for a high proportion of about 67.48% of the total investment for hydrogen-producing technology.
