Description:
The report documents an investigation of the possibility of alternate uses for surplus chlorofluorocarbon (CFC)/halon chemicals as they are replaced in their traditional service roles. hese uses may be beneficial new products or substances that are nonhazardous to the environment. Potential transformation technologies were identified from a study of literature. he two-carbon-atom CFCs and the halons offer the greatest range of possible products. he possibility of using existing CFC/ halon manufacturing facilities to produce new products by changing feedstocks is discussed. alons are assumed to have no transformation supply since residual demand for halons in their traditional roles would consume the entire available supply. arket supply calculations for CFCs were based on a number of "what if" scenarios chosen to represent low, medium, and high transformation supply cases. here is significant uncertainty in the estimates of CFC supply for transformation. FC-12 represents about 700/o of the total transformation supply bank. n engineering assessment of CFC-12 transformation chemistry is presented. o transformation process offers an immediate, clear, and economically viable option for CFC transformation.
