Abstract: The present invention relates to a method for removing high molecular weight high melting point hydrocarbon vapors from a hydrocarbon vapor offgas stream produced during the liquefaction of a solid waste plastic material to produce an oil that serves as a liquid feedstock for a partial oxidation reaction. The hydrocarbon vapor offgas stream (2) is directly contacted with a water spray (4) at a condensation temperature above the melting point of the high molecular weight hydrocarbons contained in the offgas. This results in the condensation and convenient removal of the high melting point hydrocarbons, referred to as "waxes". One or more subsequent condensation steps can be conducted at lower condensation temperatures to remove the lower temperature condensable hydrocarbons. The remaining uncondensed vapors are then recycled to serve as a heater fuel for the liquefaction of the waste plastic material.

Abstract: The present invention relates to a method for minimizing hydrogen halide corrosion in quench gasifier during the non-catalytic partial oxidation reaction of a halogen-containing hydrocarbonaceous feed, to produce a hydrogen halide-containing synthesis gas, finely divided particulate solids, and a nontoxic slag. The hydrogen halide-containing synthesis gas is contacted with water in the quench zone (14) of the gasifier (10). The quench water contains a neutralizing agent, in excess of the amount necessary to neutralize hydrogen halide acids present therein, to thereby form halide salts. The quench water containing the halide salts is purified to recover the halide salts. The salt-free water is essentially environmentally non-toxic and can either be recycled to the process or discarded in conformity with environmental regulations.

Abstract: An integrated liquefaction and gasification process converts bulk particulate halogen-containing waste plastic materials with minimal particle size reduction into a synthesis gas and a non-leachable, vitreous environmentally nontoxic slag. The process involves melting and cracking bulk particulate halogen-containing waste plastic material to form a lower boiling point, lower molecular weight halogen-containing oil composition which then undergoes partial oxidation in a quench gasifier to produce a synthesis gas. Any hazardous gases, liquids or solids that are produced can be purified into commercially valuable byproducts or recycled to the process, which does not release hazardous materials to the environment.

Abstract: An improved burner (10) for partial oxidation process gas generators is provided which has annular passages (26) formed between coaxially aligned conduits (13, 24) extending from upstream sources to the downstream reaction zone. An outer coolant jacket (21), internally baffled (22) from optimum coolant flow and sized for minimum downstream area surrounds a recessed and fuel/oxidizer delivery conduit (13) ending in a nozzle. The central delivery conduit(13) is not attached to the coolant jacket and the annular space between them (26) is connected to a high pressure supply of relatively inert gas which can periodically be vented through the annular space to prevent slag build up on the nozzle (20) or coolant jacket (21).
