Reduced Energy Costs, Lowered C02 Emissions

The Sofidel Group is one of the leading manufacturers of paper for hygienic and domestic use worldwide. Sofidel considers sustainability a strategic factor in its growth and is committed to promoting socially and environmentally responsible development. When Sofidel decided to build a new tissue production facility in Circleville, Ohio, they chose to install two Taurus 70 generator sets for combined heat and power (CHP) to optimize their process.

Sofidel`s Circleville plant uses natural gas to fire two Taurus 70 combustion turbine generator sets; one unit for each production line. Each power plant produces electricity and uses the high temperature exhaust from the combustion turbine for production and building heating needs. Some of the high temperature exhaust is directly injected into the Yankee hoods to dry the paper. The remaining thermal energy the company does not use for direct drying is routed to a heat recovery steam generator (HRSG) to make steam for the paper making process and then to a final heat exchanger to supply the building`s heating. This covers approximately 85% of the production and paper mill thermal loads, all while saving on their energy costs and reducing C02 emissions by 25.000 tons per year.
