Mitsubishi Hitachi Power Systems, Ltd. (MHPS; Yokohama, Japan; www.mhps.com) received an order from India’s public sector utility NTPC Ltd. (earlier known as National Thermal Power Corp.) for additional installations of fluegas desulfurization (FGD) systems in the Mouda-II and Rihand-II&III coal-fired power plants. This project aims to use cutting-edge FGD systems to reduce emissions of sulfur oxides (SOx) and soot dust, helping to clear and reduce air pollutants in India. This is the first order of limestone-gypsum FGD system in Indian market. Installations of Mouda-II and Rihand-II&III are scheduled for completion in 2021 and 2022 respectively.
These projects are ordered through MHPS’ Indian subsidiary and included engineering, procurement, and construction (EPC) arrangements. The order comprises two 660-MW units for the Mouda-II plant, and four 500-MW units for the Rihand-II&III plant, for a combined output of 3,320 MW. The FGD systems will be additional installations to the existing power generating facilities, supporting the design of the cutting-edge spray-type desulfurization systems handled by MHPS’ Indian subsidiary.
Coal accounts for the majority of the fuel used in thermal power plants in India, and adding FGD systems to existing coal-fired power plants is becoming increasingly common. This is a pioneering project, and the order is the result of the favorable ratings and reliability of the MHPS Group’s FGD systems.
Going forward, with the current trend toward strengthening curbs on emissions of atmospheric pollutants, demand is expected to increase for off-gas cleanup technologies and systems in thermal power plants. MHPS will proactively offer Air Quality Control Systems (AQCSs) combining high-performance, high-efficiency desulfurization /denitrification systems and dust collectors, contributing to reductions in the global environmental load.
