Application of material balance analysis (in one of our previous studies) to natural gas flare in the upstream petroleum operations confirmed the emission of primary air pollutants in form of CO, CO(2), NO, and NO(2) from "sweet" natural gas while "sour" gas emits SO(2) in addition; incomplete combustion may be an impetus for the release of volatile organic compounds (VOCs) into the atmosphere from this same source. In this article, the significance of these gaseous emissions in the formation of secondary air pollutants in the atmosphere is reviewed for the purpose of air pollution control strategy. The goal is to describe the formation mechanism, to determine the influencing factors in formation along with environmental impacts and to identify the required technological and policy control approach for an improved environmental protection.
