Abstract
A plastic pyrolysis plant, and a method of performing plastic pyrolysis, utilises a reactor (14) adapted to crack the polymeric material feedstock (1) in an environment without oxygen to convert the polymeric material into a hydrocarbon vapour and a solid carbon product called coke, wherein the reactor (14) cracks the polymeric material; and an extruder (2) to melt, heat and pump the plastic feed to the reactor (14). The extruder defines inlet ports for additives in solid, liquid or gaseous form, and at least one vent (5) for extracting any contamination vapours that may form, such that the extruder (2) is configured to remove contamination from the polymeric material feedstock (1). A contamination removal additive (3) may be introduced, through a first inlet of the extruder (2), that is mixed with the polymer feedstock (1) and that reacts to form a halide with any halogen atoms in the polymer feedstock; and which then breaks down as the temperature increases within the extruder, so as to release through a vent (5) the halogen as the hydrogen halide vapour. A fluid such as steam may be introduced into the extruder (2) at an inlet downstream of the first inlet, to assist the breakdown and release of hydrogen halide vapour through the vent (5).
