## Abstract

A process for disposing of filter media is provided, which process comprises (a) mixing a filter media with a hydrocarbonaeous mixing stream to form a media-hydrocarbon mixture and (b) feeding said media-hydrocarbon mixture to a coking vessel. Preferred coking vessels include delayed cokers, fluidized cokers, and coke calciners. An apparatus for disposing of filter media is provided, which apparatus comprises (a) a coking vessel; (b) a mixer to mix the filter media with a hydrocarbonaeous mixing fluid to form a media-hydrocarbonaeous fluid mixture; and, (c) a feed means to feed the media-hydrocarbonaeous fluid mixture to the coking vessel. Preferably, the apparatus comprises a size reduction means to reduce the size of the filter media to form a media staple comprising fiber clusters having a desired shape and size.

## Claims

### Claim 1

An apparatus for disposing of filter media in the presence of a hydrocarboneous mixing fluid, wherein said filter media is supported upon a media support and comprises a hydrocarboneous contaminant which is deposited upon or entrained by said filter media, said apparatus comprising:
a. a coking vessel operated at coking conditions;
b. a filter media removal device for removing said filter media comprising said hydrocarboneous contaminant from said media support;
c. a size reducer which subjects said filter media removed from said media support to size reduction to form a media staple comprising said hydrocarboneous contaminant;
d. a mixer to mix said media staple with said hydrocarboneous mixing fluid to form a media-hydrocarboneous mixing fluid mixture; and,
e. a feed mean to feed said media-hydrocarboneous fluid mixture to said coking vessel.
