PPG and West Virginia University performed a plantwide energy assessment at the PPG's Natrium, WV chemical plant, an energy-intensive manufacturing facility producing chlor-alkali and related products. Implementation of all the assessment recommendations contained in this report could reduce plant energy consumption by 8.7%, saving an estimated 10,023,192 kWh/yr in electricity, 6,113 MM Btu/yr in Natural Gas, 401,156 M lb/yr in steam and 23,494 tons/yr in coal and reduce carbon dioxide emissions by 241 mm lb/yr. The total cost savings would amount to approximately $2.9 mm/yr. Projects being actively implemented will save $1.7 mm/yr; the remainder are undergoing more detailed engineering study.
