A STUDY ON THE EFFICIENCY OF SELECTIVE CATALYTIC REDUCTION (SCR) SYSTEM IN REDUCING NITROGEN OXIDES (NOx) EMISSIONS FROM POWER PLANTS USING AMMONIA
Abstract
This study aimed to evaluate the effectiveness of the Selective Catalytic Reduction (SCR) system in reducing nitrogen oxide (NOx) emissions from power plants using ammonia. The study compared power plants with SCR systems to those without SCR systems at a power plant located in the Hemaraj Eastern Seaboard Industrial Estate, Chonburi Province. Data collection was carried out for two months, from the beginning of January to the end of February 2024, using continuous air quality monitoring equipment (CEMs).
The results of the study revealed that the power plant with the SCR system and using ammonia at a rate of 80 kilograms per hour was able to significantly reduce NOx levels from 45 ppm to 17 ppm, compared to the power plant without the SCR system, which had an average NOx level of 45 ppm. Furthermore, the study found that ambient temperature did not affect the efficiency of the SCR system.
