A low-cost dry flexible multi-pollutant emissions control option for the Indian power market.
published in Modern Power Systems, May 2019 issue
Tighter control of sulphur oxides (SOx ), nitrogen oxides (NOx ) and particulate matter (PM) has become a priority for many countries around the world. As an example, India’s Ministry of Environment & Forests (MOEF) has issued stringent regulations that affect an estimated 140 GW of operating coal-fired power plants and all new plants built in the future. By 2022, SO2 emissions for all operating plants in India that are 500 MWe or larger must not exceed 200 mg/ Nm3 and all new coal plants regardless of rating and other special category plants must meet even tighter SO2 limits of 100 mg/Nm3. In other words, for an existing coal plant with baseline SO2 emissions ranging from 1200 to 1400 mg/ Nm3 this amounts to an 80-90% SO2 emissions reduction from uncontrolled levels.
