Hydrocracking washing
Thread Content
I would like to ask whether, during the initial startup of the hydrogenation unit, the circulating hydrogen desulfurization system is involved in the washing and alkaline washing processes
It cannot participate in the water transportation of the distillation system; it can be transported by water separately.
Could someone on the 2nd floor explain why? Thank you
Do not participate. It is sufficient to clean the desulfurization tower thoroughly. During the hydrostatic test, it can be cleaned by flushing from the bottom discharge outlet. Water testing cannot be carried out, and the chloride ion concentration in the water must be below 25 ppm
