ABSTRACT:
Crude oil sludges and other relatively heavy hydrocarbon liquid sludges are mixed with diatomaceous earth or perlite to form a friable and flowable solids mixture which is conveyed to a combustion unit, such as rotary kiln, calciner or lift pipe type combustor, wherein combustion of the hydrocarbons is carried out to provide gaseous combustion products and a substantially hydrocarbon free solids mixture. The solids discharged from the combustion unit may be recycled for use in the mixing process to reduce the sludge to a friable material for introduction to the combustion unit and excess solids may be discharged for disposal.
