碩士 === 國立屏東技術學院 === 環境工程技術研究所 === 84 === In this study, five typical stacks of a petrochemical plant located at Kaohsiung Petrochemical Industry Park, were investigated for the concentration, emission rate and emission factor of air pollutants emitted from stationary sources, and operational parameters of stacks including SO2, NOx, CO, particulate, opacity, oxygen content, velocity, and temperature. After performing 24-hour consecutive monitoring for a period from Januaty 1, 1995 to July 31, 1995 by using a continuous emission monitoring system (CEMS) which is just installed in the end of 1994. The monitoring frequency of CEMS are once every minute for opacity and once every five minutes for SO2, NOx, CO, particulate. Then, the value for each item were averaged and presented by the hourlybasis. The results of study show that: 1. For tow petroleum industry heaters with low NOx burner the mean emission factors of particulate is 8.25 and 10.9 g/106 kcal, those of SO2 are 267 and 466 g/106 kcal, those of NOx are 58.3 and 308 g/106 kcal , and those of CO are 13.6 and 19.7g/106 kcal respectively. For two combustion boilers with low NOx burner and SCR respectively, the mean emission factor of particulate are 10.8 and 25.7 g/106 kcal, those of SO2 are 285 and 389 g/106 kcal, those of NOx are 103 and 199 g/106 kcal, those of CO are3.43 and 11.3 g/106 kcal respectively. For fluid catalytic cracking unit with both SCR and EP, the mean emission factor of particulate is 7.57 g/103 liters feed, and SO2, NOx, are 57.2 g/103 liters feed and 10.9 g/103 liters feed respectively.2. Except CO, the concentration profile of particulate, SO2 and NOx followed normal distributin. In order to reduce the possibility of air pollutant concentration exceeding the emission standards of regulation the proper management of emergency emission will be of great importance. This results of this study provide useful information for the airpollutant control of petrochemical plants associated with handling of continuous emission monitoring system, the operation of productionplants and the scientific research.
