Modeling Absorbers in WFGD System and Prediction of SO2 Removal Rate Based on Size Parameters

Abstract

In this study, research was carried out on absorber (in and exit) in the wet flue gas desulfurization (WFGD) system of a local thermal power plant. WFGD plays a vital role in terms of environment since it includes water, chloride ion, gypsum, and coal ash. In the progress of WFGD in power plants, absorber has the key role of SO2 removal. This study focuses on modeling of the absorber in the WFGD system. In the context of this study, sample from absorber in limestone slurry was analyzed based on particle size distribution (PSD) and elemental composition, and a model was proposed to predict SO2 removal rate. The model proposed employs basically the parameters previously proposed by some researchers, and in addition, the PSD, i.e., size parameters like D32 and D43. The model proposed is in good agreement with the results obtained.

Optimization of a 660 MWe Supercritical Power Plant Performance—A Case of Industry 4.0 in the Data-Driven Operational Management Part 1. Thermal Efficiency

“…By the end of June 2019, Pakistan's planned electricity generation capability was 26,887 MW e (electric power), while 63.96% of the electricity demand was met by thermal power plants [3,4]. The energy conversion efficiency, fuel consumption, and hazardous emissions from thermal power plants on the environment are critical issues of concern in research in industrial and regulatory circles in the last decade [5][6][7][8]. Various retrofits, technology improvements, and state-of-the-art air pollution control devices are integrated at the power complexes to ensure cleaner energy production with minimal emissions from the power plants that comply with various national and international standards [9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25].…”
