Quantitative Analysis of HFCs, PFCs and SF6 Emission from Thailand Industries
This study is a documented research work that determines the emission quantities of HFCs, PFCs and SF6 in Thailand. The information included in this study is comprised of secondary data that have been collected from relevant government agency sources and the results of a field survey. The field survey provides information about the production process, the production output, and the emission factors for each specific production process, extracted from the Revised 2006 IPCC Guidelines for National GHG Inventories, Volume 3. The effect of the use of HFC- 134a in the manufacturing and servicing of household refrigerators and automobile air-conditionings was calculated during 2001-2006 and the results indicated that the direct emission of HFCs based on CO2 and carbon equivalent was 59,280,394 and 16,300,616 MT carbon, respectively. Similarly, the effect of the use of SF6 in the manufacture was calculated during 2001-2006 and the results indicated that the direct emission of SF6 based on CO2 and carbon equivalent was 29,473 and 8038 MT carbon, respectively. The direct emission was calculated from the amount of HFCs, PFCs and SF6 that had leaked or had purged directly into the atmosphere. It was found that the direct emissions from manufacturing and servicing refrigerator had increased and the different emissions depend on the amount of GHG that was converted which was compared to the amount of equivalent CO2.
