Systems and methods to enhance the removal of inorganic contaminants, including metals, from hydrocarbon feedstocks at a refinery. One or more embodiments of such systems and methods may be used to provide a renewable hydrocarbon feedstock having a reduced amount of metal contaminants. The reduction of metal contaminants in the renewable hydrocarbon feedstock mitigates catalyst fouling and/or deactivation during downstream refinery processing of the renewable hydrocarbon feedstock.

Systems and methods to separate water and remove solids from a pre-treated and unfiltered renewable feedstock at or separate from a refinery. Such systems and methods may be used to provide a reduced-contaminant and reduced-solid renewable feedstock for further refining.

Provided is a method of producing dechlorinated waste plastic pyrolysis oil. The method includes (S1) putting a waste plastic feedstock containing moisture into a reactor; (S2) pyrolyzing the waste plastic feedstock by heating the reactor to a target temperature T.sub.f at a heating rate R.sub.1 of 2° C./min or less; and (S3) recovering pyrolysis oil pyrolyzed in the reactor. Step (S2) includes one or more temperature plateaus in which a predetermined temperature T.sub.1 is maintained at a temperature of 100° C. or higher for a predetermined time.

A system and method for separating bitumen and condensate extracted from separating bitumen from oil sands material is disclosed. The method includes passing the mixture of bitumen and condensate through a flash evaporator to separate them. In the flash evaporator the mixture is heated at high pressure after which it is sprayed into a tank where the pressure is much lower, allowing the condensate to vaporize and the bitumen to settle to the bottom of the tank. The vapors are then passed through a condenser unit, causing them to cool and liquefy.

The present disclosure provides an improved process for conversion of a plastic waste to fuel that is economical. An aspect of the present disclosure provides an improved process for conversion of a plastic waste to fuel, said process including the steps of: (a) contacting the plastic waste with a transporting agent in a reactor to obtain a first mixture, said first mixture being in a molten state, wherein said transporting agent is a high molecular weight wax having carbon atoms ranging from 30 to 100 and molecular weight ranging from 500 to 2000; (b) effecting filtration of said first mixture to obtain a filtered molten mixture; (c) effecting thermal cracking of said filtered molten mixture to obtain an overhead stream and a bottoms stream; and (d) subjecting said overhead stream to flashing to obtain a fuel stream and a transporting agent stream.
