Oil recovery process and apparatus for oil refinery waste
Patent
·
OSTI ID:5671341
This patent describes a process for recovery of oil from oily waste having high water content, a heavy hydrocarbon portion and inert solids. It comprises: mixing the waste with fluidizing oil to form a mixture; evaporating the water from the mixture to dewater the mixture; and feeding the dewatered mixture to a delayed coking process, including directing the dewatered mixture into a coke drum containing conventional coke feedstock and subjecting the dewatered mixture in the coke drum to coking conditions, whereby the heavy hydrocarbon portion changes to coke and light hydrocarbon material, the inert solids become trapped in the coke, and the fluidizing oil vaporizes.
