Abstract

Abstract:

In residue hydrocracking process, the unconverted oil easily agglomerates and deposits when its temperature or flow velocity is reduced, leading to the plugging of heat exchangers. Through heat transfer calcultation of spiral plate steam generator, the impact of different process parameters on oil side outlet temperature and flow velocity is investigated. The results show that the total heat transfer coefficient of spiral plate steam generator is restricted by oil side heat transfer coefficient. The outlet temperature and flow velocity of unconverted oil will reduce with the increase in heat exchanger design margin and improve with the increase in fouling resistance, heat duty or water side operating pressure. In pracitce, the oil side outlet temperature and flow velocity can be effectively regulated by adjusting water side operating pressure.
