A method for accelerating the treatment of chemical wastes, particularly recalcitrant wastes such as spent caustic, from the oil, gas, chemical, and petrochemical industries, in which normally slow physical mass transfer of different fluid phases, as well as other chemical reactions, are facilitated

A method for accelerating the treatment of chemical wastes, particularly recalcitrant wastes such as spent caustic, from the oil, gas, chemical, and petrochemical industries, in which normally slow physical mass transfer of different fluid phases, as well as other chemical reactions, are facilitated. The method involves mixing together the different fluid phases and delivering the mixture to a reaction vessel in the form of an aerosol and froth which provides a large surface area between the phases. The aerosol and froth mixture is maintained and replenished for a period of time sufficient to effect mass transfer and stripping of the contaminants to a selected level of completion. The method enables the provision of more environmentally acceptable wastes for disposal.

[ The claims defining the invention are:] [1.] A method of accelerating the reaction rate of a chemical reaction between molecules initially contained in two separate liquid and gas phases one of which phases contains contaminants and the other of which is capable of removing said contaminants, said method comprising delivering said phases from separate sources along separate paths to a jet compressor; mixing said phases in said jet compressor to form an aerosol and froth mixture; delivering the mixture and the separate liquid phase to a reaction vessel in which said mixture expands to provide a large surface area between said phases for aiding mass transfer, said jet compressor and said reaction vessel comprising a reaction stage; maintaining said mixture in said reaction vessel for a sufficient residence time to enable said chemical reaction to proceed to a selected level of completion to strip contaminants from said one of said phases; separating the resulting liquid and gas phases; and pumping the resultant liquid phase to said jet compressor to compress said gas phase.
