Phasing out of CFC refrigerants in India Speaker Mrs. Jyoti S. Jadhav

The Real Alarm 1974- Mario Molina and F. Sherwood Rowland Nobel prize (1995) The Real Alarm

Earlier refrigerants Natural ice Salt + Water Ether Ammonia Sulphur dioxide Methyl chloride Carbon dioxide Air Earlier refrigerants

Problems with early refrigerants Toxicity (Ethers, ammonia) Flammability (Hydrocarbons) Material Compatibility( Ammonia) Chemical stability (SO2) Operating pressures (CO2) Limited temperature range Problems with early refrigerants

CFC refrigerants Thomas Midgley of Du Pont, USA Boom in RAC industry 1920 CFC refrigerants

Earth’s Atmosphere

UV radiations

Ozone Depletion What is ozone? Where is the “ozone layer” Keeps out about 95% of UV rays

Consumption of ODS in India Sl. No. Sector Chemical Used 1. Foam CFC-11, HCFC-141b 2. RAC CFC-11, CFC-12, HCFC-22,HCFC-123 3. Aerosol CFC-11, CFC-12 4. Solvent Methyl Chloroform, CFC-113 5. Fire Halon – 1211 Extinguishers Halon – 1301

India and Montreal Protocol Joined on 17 Sep. 1992 Is an Article 5 country, along with 146 other countries (less than 0.3 kg. per capita ODS consumption) India and Montreal Protocol

Phase-out Schedule as per Montreal Protocol Ozone-depleting substance Developed Countries Developing Total Phase-out by 1st January of the year CFCs 1996 2010 Halons 1994 HBFCs CTC Methyl Chloroform 2015 Methyl Bromide 2005 HCFCs 2030 2040
