Ⅰ. Background and Aims of Research
o One of the key points of the 9th Basic Electricity Power Supply and Demand Plan (draft) is to reduce coal use and replace it with liquefied natural gas (LNG). This may have a positive impact on solving the problems of fine dust and greenhouse gases, but the impact of air quality caused by the use of fossil fuels (LNG) cannot be overlooked, and thus, careful air pollutant management is necessary.
ㅇ Although the standards for emission of nitrogen oxides for gas-fired power plants have recently been strengthened, it has been pointed out that management of ammonia, dust, carbon monoxide, and unburned hydrocarbons and so on, is insufficient
ㅇ In particular, since the development of LNG cogeneration plants are mostly being promoted with the development of new cities and most plants are located near the areas with high demands for heat, it can be said that air pollutant management focusing on exposures to air pollutants is important.

o This study intends to carefully establish a management plan for air pollutants for LNG cogeneration facilities, which are expected to cause severe exposure to air pollutants in expanding LNG power generation facilities.
ㅇ Accordingly, by analyzing the current status LNG cogeneration plants and reviewing alternatives, we intend to propose a new plan to minimize the impact of air pollutant emission.
ㅇ In addition, in order to suggest areas for improvement in the air pollutant management plan for LNG cogeneration plants, we intend to set out the direction for reduction facility development and derive the elements
