ABSTRACT:
The present invention is directed to an improved method for carrying out a exothermic chemical reaction with carbon dioxide in an aqueous environment. In the method, a fluid solution containing at least one chemical reactant which is exothermically reactive with carbon dioxide is provided. Liquid carbon dioxide is then injected into the solution of the chemical reactant at a pressure above the triple point of at least about 60 psig. The injection of the liquid carbon dioxide takes place under turbulent conditions wherein the liquid carbon dioxide expands to provide carbon dioxide vapor. The carbon dioxide vapor superheats to approach the exothermic reaction temperature which occurs between the carbon dioxide vapor and the chemical reactant. The chemical reactant and the carbon dioxide react in the dispersion exothermically to produce a chemical reaction product. The flow rate of liquid carbon dioxide can be controlled to control the reaction temperature without the encessity for providing any reactor cooling or heat exchange apparatus.
