The present invention provides a method and apparatus for collecting and liquefying off-gases, particularly carbon dioxide, generated by a wet oxidation of organic matter and for the on sight gasification of liquid oxygen for use as an oxidant in the wet oxidation reaction. Through a series of separation and pressurization operations, high pressure off-gases are introduced into a heat exchanger at substantially the same time as liquid oxygen. The liquid oxygen and compressed off-gases are in heat exchange relation in the heat exchanger but are isolated from one another. Heat is transferred from the compressed off-gases to the liquid oxygen whereby the off-gases are liquified and the liquid oxygen is gasified. The liquified off-gases may then be stored in appropriate storage units. The gaseous oxygen is used as the oxidant for the wet oxidation reaction. In another aspect, odor-producing compounds are removed from the off-gases by a condensation process wherein the odor-producing compounds are separated from the off-gases by condensation. In still another aspect, these odor-producing compounds are removed from the off-gases after liquifaction by a chemical operation which chemically strips the odor-producing compounds from the liquified off-gases.
A method for the wet oxidation reaction of diluted organic waste in a down-hole reaction apparatus to recover effluent off-gases, said effluent off-gases principally containing carbon dioxide, the method comprising the steps of:
