플라즈마 공정에 의해 생성된 부산물의 분석
Analysis of the Byproducts Formed by Plasma Process
플라즈마 공정에 의해 생성된 부산물의 비료로써의 활용성 및 첨가제의 필요성과 냉각수 등 공정에 필요한 자료를 확보하고자 반응기 하단에 연결된 반응부산물 tank, 반응기 내부 및 반응기 후단에서 시료를 채취하여 분석하였다. 먼저 반응부산물 tank에서 액체상태로 채취한 시료의 경우, SO4(2-) > NO3(-) > NH4(+)으로 관찰되었다. 반면에 반응기에 설치된 냉각수를 사용하지 않고 펄스를 인가하여 짧은 시간내에 실험한 후 반응기 내부(반응전극)에서 채취한 시료의 경우, 염화암모늄이 주생성물로 확인되었다. 한편 반응기 후단에서 고체 상태로 채취한 시료의 경우에는 흡습성이 강한 질산암모늄보다는 황산암모늄이 주생성물이므로 부산물을 포집하는데 bag filter도 유용하게 사용될 수 있을 것으로 예상되었다.
The samples from 3 different spots were analyzed to get information about the necessities of additives, the needs of cooling water, and the utilities of byproducts as an agricultural fertilizer. First, the liquid sample gathered from the bottom of reactor was showed SO4(2-) > NO3(-) > NH4(+). Second, the solid sample collected from reactor inside was identified ammonium chloride came from HCl of the exhausted gas. Third, the solid sample stacked in the exhausted plumbing was indicated as a very high ratios of sulfate/nitrate, therefore, a bag filter can be used as a collecting device of byproducts.
