Application of ammonia desulphurization process enhanced by streamer discharge in a project
CHEN Hui;SINOPEC Nanjing Engineering & Construction Inc.;
Ammonia desulphurization process enhanced by streamer discharge is described with respects to its technical principal, process flow,features and application in a coal-fired power plant FDS project. It was proved a successful operation with 96. 0%-99. 9% of sulphur removal efficiency and by-product ammonium sulphurate for sale as a fertilizer. With the installation of a wet electrostatic precipitator downstreams of desulphurization unit,the issues such as ammonia escape,aerosol plume and excessive acid mist emission in stack gas were also addressed.
