Iroquois Gas Transmission System in December started up its second compressor station, near Groghan, N.Y. The 6,960-hp station supplies 55 MMcfd to Selkirk 11 Cogeneration Partners' 252-mw cogeneration plant in Bethlehem, N.Y.
The plant was designed with sophisticated air-emission control and noise-suppression systems, says IGT. The gas-powered Solar Taurus turbine that drives the compressor is equipped with SoLoNOx, a low NOx emission-reduction system which has made the station a minor emission source in New York State.
Additionally, the plant uses state-of-the-art noise-abatement techniques and materials to operate at noise levels at or below guidelines established by the U.S. Federal Energy Regulatory Commission.
Iroquois' first station, near Wright, N.Y., uses two 5,650-hp turbo-compressor units and started up in late 1993. The 375-mile pipeline in New York, Connecticut, and Long Island Sound transports gas from Canadian suppliers to LDCs and power-generation markets in the U.S. Northeast.
