摘要
采用氧化剂和破乳剂,对辽河原油进行超声-氧化脱硫研究。考察反应温度、反应时间、氧化剂用量、破乳剂用量对脱硫率的影响,并比较超声波作用下氧化脱硫与单一氧化脱硫效果。实验结果表明,超声-氧化脱硫具有明显的优势,最佳实验条件为:反应温度65℃、反应时间10 min、氧化剂用量200×10-6(ppm)、破乳剂用量60×10-6(ppm)。在此条件下,原油脱硫率达65.28%。
Oxidative desulfurization of Liaohe crude oil under ultrasound irradiation adding oxidizer and demulsifier is Studied.It was researched that effects of reaction time,reaction temperature,oxidizer dosage and demulsifier dosage on desulfurization rate,while compared the effect of oxidative desulfurization under ultrasound irradiation with single oxidative desulfurization.The results show that the reaction under ultrasound irradiation would be better than usual reaction.The optimum conditions for crude oil desulfurizating are as follows: the desulfurization efficiency of crude oil can reach 65.28% under 65℃ for 10 min,with the oxidizer dosage of 200×10-6(ppm),demulsifier dosage of 60×10-6(ppm).
