Removal Efficiency of Some Odorants against Water as Sorptive Media: A Case Study on Trimethylamine and Reduced Sulfur Compounds

물을 흡수매체로 이용한 트리메틸아민과 환원황화합물의 제거효율 비교 연구

Abstract

In this study, the removal efficiency of trimethylamine (TMA) and four reduced sulfur compounds (RSC) of $H_2S$, $CH_3SH$, DMS, and DMDS was investigated using deionized water as absorbent. To this end, two types of experiments were conducted which include: (1) by passing both RSC and TMA standard gases through water contained in an impinger system and (2) by passing TMA gases through a water spray system. In the former method, TMA standard gases were effectively removed (below detection limit) in all experiments. Likewise, minor fractions of some RSC ($CH_3SH$, DMS, and DMDS) were removed by water in line with theoretical expectations. In addition, the first type of our experiment was extended further to test some commercially available odor treatment products. The results of this test showed that removal efficiencies of RSC $(8.2\pm13.7\sim43.7\pm2.48%)$ were different significantly among 4 kinds of absorbent, while the removal of TMA was consistently good as water. In the second phase of experiment, removal efficiency of TMA was tested by passing its standard gas through a water spray system. The overall results of our study showed that the actual removal efficiency of odorants by water (as sorptive media) approached the values that can be predicted theoretically (by Henry's law).
