Catoxid® Catalytic Oxidation

OxyVinyls' Catoxid® catalytic oxidation process catalytically oxidizes liquid chlorinated hydrocarbons, including heavy and light ends from VCM and chlorinated solvent processes, at a relatively low temperature. The resulting gaseous product stream (containing CO2, HCl and water) is ideal for recycling to a fluid bed oxychlorination process where the HCl is reacted to a useful product.

The process' mild operating conditions enhance operational safety and permit a design using standard, easily obtainable alloys. These mild operating conditions are made possible through the use of OxyVinyls' patented Catoxid® 5 catalyst, which ensures complete conversion of chlorinated organics at a relatively low operating temperature. The simple process contains only a feed air compressor, reactor, catalyst storage and steam generation equipment, which results in relatively low capital costs and minimal downtime. Full recovery of chlorine value and a significant credit for high pressure steam generation make the OxyVinyls Catoxid® process more economical than other currently available technologies.

The Catoxid® process has been in commercial operation since 1974, and is licensed around the world. The Catoxid® process replaces high-temperature, atmospheric pressure incineration units.

The OxyVinyls Catoxid® process represents the best fluid bed technology and is successfully used in conjunction with OxyVinyls' ethylene oxychlorination process.
