Abstract: A brief analysis of the reasons for the large pressure drop in the pre-hydrogenation of the catalytic reforming unit and some solutions are proposed. It is found that the use of an automatic backwash filter can effectively solve this problem. The results show that the filter works well and the pressure drop of the pre-hydrogenation reactor is stable which is 60~80kPa, and the problem of rapid pressure drop of pre-hydrogenation reactor is solved; the frequency of device shutdown and column filter cleaning reduced. A good filtration effect and terrific economic benefit is achieved, and a long-period operation of the device is ensured.

Key words: Automatic backwash filter; catalytic reforming; pre-hydrogenation; pressure drop
