초록
아민 수용액의 거품 안정화도를 측정하기 위해서 AMP수용액의 거품소멸 시간을 여러 온도인 20 ℃에서부터 80 ℃에 걸쳐서 측정하였다. AMP수용액의 경우 65 ℃근처에서 거품소멸 기구가 달라지는 현상을 보였으며, 온도증가에 따른 에너지장벽의 변화로 이와 같은 현상을 설명 할 수 있다. DEA, MDEA, AMP와 같은 여러 아민 수용액의 거품 생성도를 실험을 통해서 알아보았다. 실험온도와 아민 수용액에서의 아민 농도의 변화로부터 혼합물의 거품생성도는 아민 수용액의 물성에 크게 영향을 받는다는 것을 확인 하게 되었으며, 특히 밀도, 점도 그리고 표면장력과 같은 물성들이 거품 생성도에 크게 영향을 미친다는 것을 알게 되었다.
Foam decay time of aqueous 2-amino-2-methyl-1-propanol mixture was studied experimentally at various temperatures between 20 and 80 ℃. Foam stability mechanism was changed at 65 ℃. For the purpose of analyss of these results we assume that the additional barrier of foam decay is proportional to operating temperature. We measure foamability at a various operating temperature and amine concentrations in the aqueous diethanolamine, N-Methyldiethanolamine and 2-amino-2-methyl-1-propanol mixtures. The results showed that density, viscosity and surface tension play an important role in the foamability.
