Analysis of Influencing Factors of Long Cycle Operation of Diesel Hydro-upgrading Unit
In view of the inferior quality of raw materials,the influence of raw fuel density,temperature point of 95%distillation range and sulfur content increase on catalysts,plate blockage of desulfurization tower and crystallization of ammonium salt of reaction effluent steam generator E9102 and other factors affecting the long cycle operation of the unit are analyzed.Solutions such as optimizing raw materials,improving the quality of amine solution,exploring the use of new anti-clogging tray and online washing solutions to solve the crystallization of ammonium salt,are proposed to achieve long cycle operation of the unit.
