연면방전 반응기로부터 발생하는 플라스마에 의해 NO, NO₂, SO₂등 유해가스의 제거율을 구하여 SO₂, 5.21 %/W, NO 4.76 %/W 및 NO₂4.24 %/W의 순으로 제거율을 나타내었다. 유해가스의 체류시간이 길수록, 초기농도가 작을수록 제거율은 증가하였다. 방전전극에 대한 영향은 전극의 굵기가 굵을수록 제거율이 증가하여 3 ㎜의 전극이 가장 높은 제거율을 나타내었고, 전극의 재질은 텅스텐, 구리, 알루미늄의 순으로 제거율이 낮아졌다. 첨가물질로 메탄을 사용한 결과, 메탄을 첨가할수록 제거율은 증가하여 99%로 거의 완전히 제거할 수 있었다. Hazardous air pollutants(HAP) such as NO, NO₂and SO₂were removed in SPCP reactor and the removal efficiencies per unit power of each pollutants were 5.21%/W for SO₂, 4.76%/W for NO and 4.24%/W for NO₂. The efficiency was increased by increasing the residence time and by decreasing the initial concentration of pollutants. The highest decomposition efficiency was obtained for the electrode diameter of 3 ㎜. For the electrode material, the removal efficiency changed with the electrode material in the order of W>Cu>Al. The removal efficiency increased with the CH₄content, and HAP was almost completely removed with the efficiency of 99% respectively.

개방형 왕복 다공판 추출탑을 이용한 액막법에 의한 폐수중 Cr(VI)의 추출
우인성,안형환,강현춘 한국산업안전학회 1993 한국안전학회지 Vol.8 No.2
The objective of this study was to investigate the extraction of chromium(VI) ion in waste water through the liquid surfactant membrane with open-type Perforated Reciprocating-Plate Column. Extraction experiments were conducted to measure the effect of flow characteristics of continuous and dispersed phase and stroke velocity, sodium hydroxide concentraction in internal aqueous phase, sulfuric acid concentraction in outer phase, and residence time distribution and measured extraction velocity. The result of experiments showed that extraction velocity of chromium ion was maximum when stroke velocity was 180 ℓ/min and dispersion phase velocity was 30㎖/min, continuous phase velocity was 20㎖/min. Extraction velocity of chromium ion increased with increasing difference of hydrogen ion concentraction of dispersion and continuous phase and column stage decreased.

방전플라스마에 의한 NOx , SOx 분해시 메탄첨가의 영향
우인성,강안수,강현춘 한국산업안전학회 2000 한국안전학회지 Vol.15 No.2
For hazardous air pollutants(HAP) such as NO, NO₂ and SO₂ decomposition efficiency, power consumption, and applied voltage were investigated by SPCP(Surface induced discharge Plasma Chemical Processing) reactor to obtain optimum process variables and maximum decomposition efficiencies. Decomposition efficiency of HAP with various electric frequencies(5∼50 ㎑), flow rates(100∼1,000 mL/min), initial concentrations(100∼1,000 ppm) and additive(CH₄) were measured and the products were analyzed with FT-IR. Experimental results showed that for the frequency of 10 ㎑, the highest decomposition efficiency of 94.3 % for NO, 84.7 % for NO₂ and 99 % far SO₂ were observed at the power consumptions of 19.8, 20 and 19W, respectively, and that decomposition efficiency decreased with increasing frequency above 20 ㎑. And decomposition efficiency per unit power were 5.21 %/W for S02, 4.76 %/W for NO and 4.24 %/W for NO₂ and the highest decomposition efficiency was observed with SO₂. Decomposition efficiency was increased with increasing residence times and with decreasing initial concentration of pollutants. When the additive of CH₄ was used, decomposition efficiency was increased with increasing CH₄ content, and NO, NO₂ and SO₂ were almost completely decomposed with the efficiency of 99 %, 98 % and 99 %, respectively and therefore CH₄ was a good additive material. The optimum power for the maximum decomposition efficiency were 7.5 W for SO₂, 9.5 W for NO and 15.5 W for NO₂, respectively. Optimum power with the maximum decomposition efficiency were 9.5 W at 1,000 ppm of NO, 7∼8 W at 100∼500 ppm of NO and 15.5 W at all concentration range of NO₂ and 11.5 W at 1,000 ppm, 4.9 W at 500 ppm, 3.7 W at 100∼300 ppm of SO₂ and power efficiency was best in these case.

In this study. SO₂ and NO₂ reduction have been investigated by using coil type plasma reactor. The experiments have been carried out changing discharge power, gas flow rate frequency and electrode style to obtain the decomposition rate. Decomposition rates of SO₂ and NO₂ were obtained 20∼98% at gas flow rate 100㎖/min∼1,000㎖/min and discharge power 5∼25w respectively. The energy efficiency is very good at the high frequency power. The decomposition rate of SO₂ for 5㎑ power supply is only 90%, but for 10㎑ power supply is very high, more than 98% for 15w. The decomposition rate is increasing according to the residence time or the power consumption of the discharge. About 15W discharge power for 17㎤ reactor is necessary to obtain the decomposition rate of SO₂ and NO₂ of more than 85% or 98%. From these experiments, the consumption power of the decomposition rate of 98% in 300ppm NO₂ gas in nitrogen gas proved to be 18W and 300ppm SO₂ gas to be 15w.

Coil형 플라즈마 방전반응기에 의한 황산화물과 질소산화물의 분해
안형환,우인성,조정국,강현춘,강안수 明知大學校 産業技術硏究所 1999 産業技術硏究所論文集 Vol.18 No.-
In this paper we have presented an approach to decomposition and removal of SO₂ and NO from flue gas by plasma technology. It was investigated that SO₂ and NO₂were reduced in a coil type plasma reactor at various conditions and parameters such as flue gas flow rate, discharge power frequency, and the type of electrode. About 20∼98 % of SO₂and NO₂were decomposed st the gas flow rate of 100∼1,000mL/min and the discharge power of 5∼25 W. with the higher frequency the more efficient decomposition rate have been obtained. About 90 % and 98 % of SO₂were removed at the discharge power of 15 W and the power supply of 5 ㎑ and 10 ㎑, respectively. The decomposition rate of SO₂ and NO₂were increased with increasing the residence time and the electric power, and with decreasing initial concentration of pollutants. In a plasma reactor(volume:17㎤) with discharge power of 15 W, 85 % of SO₂and 98 % of NO₂were decomposed. The power consumption for the decomposition of 98 % of SO₂and NO₂(initial concentration of 300 ppm each) have been proved to be 15 W and 18 W, respectively.
