Abstract

This study aims to model the dispersion of two pollutants: nitrogen oxides (NOx) and sulfur dioxide (SO2) from an onsite biogas fueled generator by using CALPUFF modeling system. CALPUFF is a non-steady state puff simulating software that takes into account, meteorological data, terrain data and land use data, to effectively simulate dispersion from a given source. These data are taken from the different governmental and accredited organizations and used in conjunction with CALPUFF. Results showed a wider dispersion of both pollutants in January as supposed to June. This was due to rapid changes of wind’s speed and directionin the month of January. It was also discovered that the emission results were well below the point of impregnation (POI) limits set by the Ministry of Environment for its 24 hour, 1 hour and 30 minute averaging time periods of exposure. The findings of this study reveal that the proposed facility’s operation is in compliance with the Ontario regulations and that it should be able to operate in accordance with them, in the winter and summer seasons.

模拟拟建的沼气生产设施排放的氮氧化物和二氧化硫的扩散

本研究旨在利用CALPUFF建模系统模拟现场沼气燃料发生器中氮氧化物(NOx)和二氧化硫(SO2)两种污染物的扩散。CALPUFF是一个非稳态泡芙模拟软件，它考虑了气象数据、地形数据和土地利用数据，可以有效地模拟给定源的色散。这些数据来自不同的政府和认可组织，并与CALPUFF一起使用。结果显示，1月份这两种污染物的扩散范围比6月份更广。这是由于1月份风速和风向的快速变化。调查还发现，排放结果远低于环境部规定的24小时、1小时和30分钟平均暴露时间的浸渍点(POI)限值。这项研究的结果表明，拟议的设施的运作符合安大略省的条例，它应该能够在冬季和夏季按照这些条例运作。
