摘要
综述了目前国内外轻质油品溶剂萃取脱硫的相关技术,并进行比较和评价。认为单一的溶剂萃取脱硫技术存在着碱液排放量大、脱硫率不高的问题,多种脱硫技术相结合是深度脱硫的发展趋势。离子液体由于可以循环使用,必将是一项非常有发展前途的脱硫技术。
The desulfurization technologies of light oil were introduced briefly and several treating technologies were compared and evaluated in the paper. Solvent extraction used only can make more alkali liquid and has lower desulfurization efficiency. Desulfurization technologies by solvent extraction combining with other technology are the trend of deeper desulfurization. The ionic liquid is a potential solvent for desulfurization because of its recycling use.
