Gas Turbine Units for Pipeline Compressor Stations: Environmental Update Problems

The exhaust of nitrogen oxides into atmosphere is the most stringent environmental challenge in the operation of gas pipeline gas turbine plants. In 1991–1993 NITI EM along with EKOL retrofitted over 170 GTK-10 and GT-750-6 type gas turbine combustors of the “Tyumentransgas” and “Transit” (Czech Republic) gas transmission enterprises. Operations were carried out directly at the gas pumping stations.Emissions of the retrofitted units are within a range of 135–175 mg/Nm3 of oxides of nitrogen (NOx) referred to 15% O2 and carbon monoxide (CO) content of the exhaust gases does not exceed 100 mg/Nm3, at 15% O2.Copyright © 1994 by ASME
