Abstract

본 연구에서는 Tergitol 계열 비이온 계면활성제 시스템에 이온 계면활성제와 보조 계면활성제를 각각 첨가한 경우에 있어서의 원유 중에 포함되어 있는 황화합물 가용화도에 관하여 살펴보았다. Sodium oleate, potassium oleate, CTAB와 DTAB 등의 이온 계면활성제 첨가는 비이온 계면활성제에 의한 황화합물 가용화도에 큰 영향을 미치지 않는 반면에 사슬 길이가 긴 알코올을 보조 계면활성제로 첨가한 경우에는 원유 중의 황화합물 가용화도가 증가하였다. 알코올의 첨가 효과는 계면활성제가 수용액 상으로부터 오일 상으로 이동하는 partitioning 현상으로 인하여 사용한 원유 양이 증가할수록 작아지며, 또한 사용한 알코올의 사슬 길이에 따른 가용화도 증가 차이도 작게 나타났다. 원유와 계면 활성제 수용액 사이의 계면장력은 온도가 증가할수록 감소하였고 소수성의 계면활성제일수록 감소의 폭이 증가하였다. 수용액의 pH 변화에 따라 황화합물의 가용화에는 큰 변화가 없었으며, 탈황 미생물 성장 영향 실험에서 계면활성제 혹은 보조계면활성제의 첨가는 탈황 미생물의 성장에 큰 영향을 끼치지 않음을 확인할 수 있었다.
In this study, the effects of additives such as ionic surfactant and cosurfactant were studied on the solubilization of sulfur compounds contained in the crude oil by Tergitol series nonionic surfactants. It was found that the addition of an ionic surfactant such as sodium oleate, potassium oleate, CTAB and DTAB did not enhance solubilization capacity of Tergitol series nonionic surfactant. On the other hand, the addition of a long-chain alcohol as a cosurfactant increased the solubilization of sulfur compounds in the crude oil. The effect of alcohol was found to become reduced with an increase in the amount of crude oil used mainly due to partitioning phenomena of an nonionic surfactant. The enhancement of solubilizing capacity of Tergitol series nonionic surfactant with addition of a cosurfactant was associated with a decrease in interfacial tension between crude oil and surfactant solution. The pH of Tergitol nonionic surfactant solution did not affect the solubilization of sulfur compounds. Finally, it was found that the growth of sulfur reducing microoganisms was not greatly affected by both addition of nonionic surfactant and cosurfactant.
