The emission allowance standards for business establishments are strengthened and financial charging for NOx emission is considered. And total maximum loading system and emission trading system are also planned in Seoul metropolitan area. Some basic data such as performances and cost of NOx control technologies are required for such measures to be implemented effectively, but few materials are available. So this study was carried out to assess performances and costs of NOx control technologies. This paper investigated the reduction efficiencies and costs of NOx control technologies used in industry and estimated the required capital cost to install of selective catalytic reduction(SCR) equipments for high energy-consuming industrial sectors. Reduction efficiency varies depending on techniques, and it is possible up to 90% or more. So technology itself cannot be a barrier in implementation of MOE countermeasures. But it is worried that NOx market produced by the above countermeasures may be occupied by foreign technologies because of lower level of technologies and little experience of domestic environment businesses. Details are presented in Chapter b! and c!. Capital and operating costs of SCR, SNCR and low NOx burner were investigated for domestic power plants, municipal waste incinerators, and a few other businesses. For example, capital costs of SCR are about 29.3 million won/MW, 22.3 million won/MW, and 5.3 million won/ton of waste/day for oil-fired power plants, gas-fired power plants, and municipal waste incinerators, respectively. In the case of United States, average cost effectiveness of control technologies are about 1.095 million won/ton of NOx, 1.932 million won/ton of NOx, and 4.893 million won/ton of NOx for low NOx burner, SNCR, and SCR, respectively. Total capital cost of add-on SCR installing for high energy-consuming industrial sectors was estimated based on the surveyed data or energy consumption. The estimates are 550^954 billion won for power plants, 174^235 billion won for cement industry, 171^231 billion won for basic iron and steel manufacturing, 30^41 billion won for glasses and glass products manufacturing, 105^141 billion won for oil refinery facilities, and 40 billion won for waste incinerators. The estimated NOx reduction amount by installing SCR for those industries is about 0.21^0.25 million ton. Assuming depreciation period of 15 years, the annualized capital cost for reduction of 1 ton of NOx is about 0.997^1.380 million won. If operating cost is included, total annual cost will be more expensive. It might become a burden in cost to the enterprises. Therefore, financial charging system and emission trading system might be checked to gradually apply to enterprises for reducing the burden in cost and considering the period for applying the domestic technologies.1 ` <br> <br>2 ɌT< 0i i <br> 1.
