Abstract: The residual oil filter is a key equipment in the residual oil hydrogenation unit, and its accuracy and operating condition have great impact on the stable operation of the unit, the pressure drop of the reactor and the service life of the catalyst. The failures such as cracks, deformation and corrosion of the filter element during operation will directly affect the safe, stable and long period operation of the device. Aiming at the aforementioned problems, this paper brings forward the measures to improve the filters based on the tracking and analysis of the operation conditions about the residual oil filters in 14 sets of residual oil hydrogenation units from 13 enterprises.

Key words: residual oil hydrogenation, filter, fault, localization
