EMISSION CONTROL OF STATIONARY ENGINES IN POWER GENERATION

ABSTRACT

Diesel and natural gas engines are widely used in the power generation sector for emergency back up as well as for prime power generation. Accordingly, stationary generators significantly contribute towards the pollutant emissions in today’s cities. In order to improve the ambient air quality in Asian cities, it is necessary to reduce such emissions from the gen. sets, especially those using diesel fuel. Several emission control technologies have been developed and successfully implemented by Johnson Matthey to achieve such emissions reductions from stationary engines. These technologies include oxidation catalysts, selective catalytic reduction (SCR) systems and diesel particulate filters. The emission components treated by such technology include Carbon Monoxide (CO), Hydrocarbons (HC), Aldehydes, Nitrogen Oxides (NOx) and Particle Matter (PM). Details about such systems and their applications will be presented in this paper.
