The Benefits and Challenges of Filter Cleaning & Testing in rHCU Applications

Presented By

Sue L. Reynolds - Carolina Filters Inc.


Various forms of filtration are used in oil refining applications. Typical issues related to inadequate cleaning & the quantification of cleanliness for metal filters used in Residue HydroCracking applications are increased maintenance costs, lower throughput, and compromised product quality.

Carolina Filters, Inc. has developed a proprietary method for removing asphaltenes, organics, and inorganic catalysts fines/sulfur from metal filters, along with, testing methods that quantify the media cleanliness. Bringing the filter media matrix back to a ‘like new’ condition will minimize or eliminate the typical issues related to inadequate cleaning. Effective cleaning & testing will also reduce costs associated with spare filter inventory purchases. While there can be challenges to cleaning metal filters for re-use, there are benefits to pursuing cleaning.
