Total SO 2 emission control strategies for the management of air pollution in ulsan industrial complex

Abstract

Since emission regulations in Korea concentrate mainly on the limitation of pollutant concentration in the stack gas, it is difficult to achieve a desirable air quality in a heavily industralized city like Ulsan. To ensure a suitable air quality in the future, a total emission control method is proposed with a stack height formula of H = 10.6 q 0.5, where H is the stack height (m) and q is the SO 2 emission rate (m 3 h −1 reduced to 0°C). The total emission permitted can be allocated to industries 1. (1) at an uniform reduction rate, 2. (2) by the formula Q = a Q o 0.925, where Q is the emission allowed (g s −1), a is a constant, and Q o is the emission before control (g s −1), or 3. (3) by using a linear programming technique. The above three approaches were evaluated using the TCM 2 air quality model. In order to achieve the air quality goal set for the area, the first approach requires 38.7 % reduction of SO 2 emission from industries, the second 53.3 %, and the third 4.3 %. The linear programming method is found to be very economical, but there are some administrative difficulties in enforcement.
