Sylvan Source Heat Recovery Utilization Technology Provides Cost and Performance Breakthroughs for Industrial Plants

Proprietary thermal transfer mechanism moves large amounts of thermal energy within industrial plants - minimal losses, no chemicals or pumps

Sylvan Source, Inc. (SSI), a water and energy technology company with an innovative and flexible suite of technologies applicable to a broad range of industrial and municipal applications, today announced breakthrough performance and cost structure results for its Heat Recovery Utilization Technology (HRUT).

SSI recently completed an evaluation validated by an independent industry expert of its HRUT, which cost effectively captures, transfers and reuses a wide range of recoverable energy in industrial plants, including waste heat. SSI’s HRUT is a significant enhancement of the proprietary thermal transfer technology used in its advanced water treatment system, providing substantial capital and operating cost advantages.

Capital Cost Implications:

According to the U.S. Energy Information Administration (USEIA), each kilowatt of new coal plant capacity costs approximately $3,000. The recent evaluation determined that SSI’s HRUT would recover the equivalent of 22 megawatts of electric power from a representative 500 MW coal-fired plant’s flue gas and reuse it for preheating boiler feedwater. The capital cost of SSI’s HRUT in this application was estimated to be in the range of $17 million, including installation. Using USEIA estimates, 22 megawatts of capacity would cost $66 million for a coal-fired plant, which indicates a savings of $49 million. The comparable savings for a combined cycle plant, although smaller, are still significant.

Operating Cost Implications:

Recovering 22 MW of electric capacity in a coal-fired plant saves the equivalent of 10.7 tons/hour of coal, assuming 35% overall plant efficiency. Significant operating cost reductions are also available for other types of power plants. SSI’s HRUT is able to move thermal energy without using plant steam, thermal fluids or pumps.

The primary environmental impact of SSI’s HRUT is the ability to increase the power output of an industrial plant with no increase to the plant’s carbon footprint.

“Our heat recovery technology will be a game-changer for both new and existing power plants, and will be applicable to a wide range of other industrial plants and processes as well,” said Laura Demmons, SSI Chairman and CEO.

This technology is covered by one of the patent applications owned by SSI and filed in several countries and regions around the world.
