A pyrolysis injector includes a feeder unit with a first inlet for particulate polymeric material and a second inlet for oil, wherein said first inlet and said second inlet lead to a reservoir arranged for mixing said particulate polymeric material and oil into oil-wet particulate polymeric material, and with one or more feeding auger arranged in a feeder gutter portion of said reservoir, the feeder gutter portion leading to a narrowing pipe portion about an end portion of the one or more feeder auger arranged for compacting the oil-wet particulate polymeric material for form a compacted oil-wet particulate polymeric material, the narrowing pipe portion leading to a compacting pipe which is arranged for feeding the compacted oil-wet particulate polymeric material to a third inlet of a pyrolysis reactor, the pyrolysis reactor provided with at least one first outlet for pyrolysis fluids in gaseous form, one or more first heating elements arranged for heating the reservoir with the oil-wet particulate polymeric material (and oil) present therein, and for boiling off water and/or chemicals, one or more second heating elements arranged on the compacting pipe with the compacted oil-wet particulate polymeric material and arranged for pre-heating the compacted oil-wet particulate polymeric material before injection to the third inlet of the pyrolysis reactor, and wherein the second inlet for oil is arranged for receiving a part of an intermediary pyrolysis fluid of the pyrolysis fluids in a condensed liquid state back to the reservoir.

A retractable center feed injection device can be employed to feed residual oil into a coke drum as part of a delayed coking process. The retractable center feed injection device can include a housing within which the injection nozzle slides between an extended and a retracted position. A feed inlet is positioned on an opposite side of the coke drum from the retractable center feed injection device. When in the extended position, the injection nozzle can couple with the feed inlet and thereby form an extension of the feed inlet into the center of the coke drum. In this way, the residual oil never flows through the housing.

A reactor and its internals used for the thermal processing of a liquid mixture. The reactor comprises plates and at least part of the surface of said plates is used to perform the thermal processing. The reactor and its internals are used for the thermal processing of various liquid mixtures containing organic compounds. The processes, for thermal processing the mixture comprising organic compounds, comprising the steps of feeding the reactor and its internals and being useful for treating wastes oils and/or for destroying hazardous and/or toxic products; and/or for reusing waste products in an environmentally acceptable form and/or way, and/or for cleaning contaminated soils or beaches, and/or cleaning tar pits, and/or use in coal-oil co-processing, and/or recovering oil from oil spills, and/or PCB free transformed oils. A process for fabricating the reactor and its internals is also proposed.
