Properties and Applications of Industrial Halocarbons

摘要: Chlorofluorocarbons (CFCs) were developed in the 1920s and 1930s to replace hydrocarbon other refrigerants that, by engineering standards of time, considered unsafe. Growth into applications many market industrial sectors followed and, with phaseout CFCs under Montreal Protocol, there is a significant for replacement products such as halocarbon alternatives or historical fluids - hydrocarbons, ammonia water. The factors determining choice product are discussed. Scenarios future emissions halocarbons also developed. These based on both underlying demand shown growth HCFCs (hydrochlorofluorocarbons) extents which that met each group substitute materials improvements technology, better containment effective recycling. atmospheric concentrations alternative fluorocarbons (particularly hydrofluorocarbons, HFCs) resulting from these scenarios compared previous work Intergovernmental Panel Climate Change relied macro-economic estimates.
