장기 대기오염확산모형의 국내적용을 위한 기상결합빈도함수의 풍속등급 수정에 관한 연구

Many long-term air pollution models have been used in KOREA. But these models were developed in U. S. A., and some parameters do not reflect the climatological characteristics of KOREA. This paper analize the frequency of wind speed in Seoul, and modify the wind speed class in climatological joint frequency function (JFF) to make it applicable in Seoul, and modify TCM-2 program for new JFF. Then conventional JFF and modified JFF are compared by TCM-2. it was found that the correlation coefficient by conventional JFF is 0.519 and that of modified JFF is 0.523. And difference between observed value and predicted value by modified JFF is reduced to 4.3㎍/㎥ as compared with 36.0㎍/㎥ by conventional JFF.

The emission inventory is a system for an emission calculation by standard methodology and management for air pollution emission data produced. The emission inventory system produced an important basic data for air pollution impact assessment, total emission regulation and establishment and assessment of air quality management plan. Air quality in Seoul metropolitan area is deteriorated year by year, especially high ozone concentrations are measured recently. So an emission inventory system is needed to improve air quality in this area. The emission inventory of U.S.A. and European Union has produced air pollutants emission estimation as well as greenhouse gas from various systematic source categories. This paper produce a review about an emission calculation method and estimation models of these countries, shows a status and limitations of Korean emission inventory. To develop an emission inventory in Korea, it is necessary that greenhouse gases and hazardous air pollutants as well as criteria pollutants are listed and managed. In Kyonggido, investigations to emission facilities, especially illegal facilities, are necessary. Also it is necessary that emission from agricultural open burning, illegal waste incineration are surveyed and calculated in Kyonggi area.

수도권지역의 대기질 현황과 변화추세(1989-1995)
장영기 수원대학교 산업기술연구소 1996 산업기술연구소논문집 Vol.11 No.-
The air quality levels and annual trends were analyzed in Seoul and 10 cities of Gyongky area for recent years(1989-1995). The annual trends and characteristics of SO₂, TSP, NO₂, CO, O₃in these cities were compared. In this area the concentrations of SO₂, TSP were improved, but the degree of improvement of Gyongky area less than that of Seoul. And the annual trends of SO₂, NO₂ emission were investigated. The SO₂emission was decreased in Seoul, but emission in Gyongky area was increased in same period. And the level of NO₂, O₃was increased, specially O₃level was sharply increased in this area. The number of violation for ambient O₃quality standard was increased. Ozone alert system was promulgated in Seoul from 1995. And this results indicates that ozone alert system is needed in Gyongky area immedately.

중유를 연소하는 D 발전소 탈황설비는 운전시간의 경과에 따라 흡수탑 내부에 석고 스케일이 부착되어 발전가능 최대출력의 하향조정이 발생되고 나아가 발전정지를 초래한다. 스케일 제거를 위한 탈황설비 세정은 발전가능 최대출력의 하향조정이 발생하는 시점으로 결정할 수 있다. 본 연구에서는 탈황설비의 운전 자료를 분석하여 발전가능 최대출력의 하향조정이 발생되기 6주전은 탈황설비 출구 $SO_2$ 농도값이 130ppm을 초과하고 동시에 흡수탑 차압은 $380mmH_2O$을 초과하며, 직전 흡수탑 세정 이후 44주가 경과된 시점이 됨을 확인하였다. 최종적으로 흡수탑의 세정시기는 직전 세정시점으로부터 50주가 경과된 시점임을 예측하였다. In desulfurization facilities of oil-fired power plant, gypsum scale is attached in the absorber inner surface as the operating time increases. For this reason, the maximum possible load of the power generation is set down, resulting in further generation stop. Cleaning of absorber for scale removal can be determined at the time of setting down of the maximum possible load. In this study, 6 weeks before the maximum possible load of the power generation was down set, at the same time and desulfurization facilities outlet $SO_2$ concentration value was more than 130ppm, absorber differential pressure exceeded $380mmH_2O$, it was confirmed to be the time that has elapsed 44 weeks after the previous absorber cleaning. Cleaning time of the absorber was predicted to be a time which has elapsed 50 weeks from the previous cleaning time.

The term of factory automation is used extensively to indicate manufacturing methods which range from processing products with automated machine to automated integration of management and manufacturing activities through whole factory, progressing level by level supported by the development of technology(hardware). After formalizing the level of factory automation a survey on Korean manufacturing industries and its investigation were performed. Since other surveys had been done already the survey was designed to avoid overlap, rather to attach importance to production management and organizational changes. Some suggestions to accelerate the factory automation are proposed for both government and individual enterprise.

The purpose of this study was to estimate the greenhouse gas omissions from source categories in Kyonggi-do in 1999, and characteristics of emission in this area were compared with nation-wide emissions. Revised 1996 IPCC guidelines and emission factors recently reported in Korea were used to estimate emission of greenhouse gas. In this study, CO₂ emission was estimated as 44,668 thousand tons, CH₄ as 190 thousand tons and N₂O as 1.0 thousand tons in Kyonggi-do, 1999. So greenhouse gas emission in this area was estimated as 13,414 thousand tons of carbon equivalent, and this emission was correspond to 11.4 precent of nation-wide emissions and 1.48 tons of carbon equivalent per capita. And it was estimated that CO₂ was contributed as 91.4 %, CH₄ as 8.0 % and N₂O as 0.6 % to the total greenhouse gas emission in Kyonggi-do, 1999. The characteristics of greenhouse gas emission in Kyonggi-do were analyzed that portions of emission from residential part(26.0%) and transport part(25.5%) were higher than portions of nation-wide emission. On the other hand, a portion of greenhouse gas reduction by forestry in Kyonggi-do was lower than that of nation-wide. It is believed that these characteristics were due to construction of new cities and higher population growth in this area.
