DU PONT AUTHORIZES WORLD'S FIRST COMMERCIAL-SCALE PLANT FOR HFC-125

 DU PONT AUTHORIZES WORLD'S FIRST COMMERCIAL-SCALE PLANT FOR HFC-125
 WILMINGTON, Del., Jan. 21 /PRNewswire/ -- Du Pont (NYSE: DD) has authorized the world's first commercial-scale plant to produce hydrofluorocarbon (HFC)-125 at the company's Deepwater, N.J., site.
 The facility, scheduled for start-up in mid-1992, also will produce hydrochlorofluorocarbon (HCFC)-124. It will manufacture millions of pounds of each compound annually. Investment was not disclosed.
 "This will be Du Pont's third major CFC alternative facility in the U.S.," said Joseph P. Glas, vice president and general manager - Fluorochemicals. "Each compound represents a significant step in Du Pont's commitment to an accelerated phaseout of CFCs and will provide lower cost conversion options for equipment manufacturers."
 HFC-125 ("Suva" Freez-HP) does not deplete the ozone layer. It is targeted as a single component refrigerant and as part of the "Suva" HP series of blends to replace R-502 in commercial refrigeration applications including supermarket display cases and freezers and in refrigerated transport systems. HFC-125 also has potential for replacement of ozone-depleting refrigerants in other low temperature applications.
 HCFC-124, which is currently produced by Du Pont at Corpus Christi, Texas, is 98 percent less ozone depleting than CFC-114. It is commercially available as a single component refrigerant, "Suva" Chill- LP, for commercial and industrial chiller units and industrial air conditioning. It also is a component of the commercially available "Suva" MP series of CFC alternative blends for servicing existing and new equipment in home, some supermarket applications and commercial refrigeration systems. Blends for automobiles and refrigerated transport are targeted for availability later this year.
 Additionally, both HFC-125 and HCFC-124 are under development as replacements for Halon fire extinguishants and for use in sterilant gas applications.
 CFC alternatives identified to date are not drop-in replacements for CFCs. Du Pont's "Suva" MP and HP refrigerants will minimize the cost for servicing existing systems due to the equipment changes required to convert from CFCs. The proper retrofit of these systems to alternatives will maintain most of the $200 billion in equipment that depends on CFCs globally.
 While the company's policy is to phase out bromine and chlorine- containing compounds as soon as possible, Du Pont will cease Halon and CFC production for sale in developed countries no later than year-end 1994 and 1996, respectively. In addition, the company will discontinue sales of HCFC-22 -- among those HCFCs with higher environmental impact -- for new equipment and products in developed countries by 2005. Production of HCFC-22 will continue for service of existing equipment until 2020.
