硫酸烷基钠的绿色环保工艺

Green Environmental Protection Technology of Sodium Lauryl Sulfate

通过对硫酸烷基钠生产影响因素分析,并对具体工艺过程的气体SO_3多管膜式磺化、高浓度中和以及绿色节能干燥单元进行研究,从品质、节能、安全和环保等角度表明产品的产业化,不仅需要精细化控制整个工艺过程来提高转化率、防止副反应、增加脱水效果,达到降低产品内无机盐、未磺化物和水等物质目的,还要充分使用先进生产设备、创新技术手段和智能化控制方法,进一步提升产品质量,降低生产成本,强化粉状物料生产的安全保护功能,降低环境压力。

The influencing factors process of lauryl sulfate production was analyzed. The process of gas S03, multi tube membrane sulfonation, high concentration neutralization and green energy saving drying unit were studied. The industrialization of high purity products is demonstrated in terms of quality, energy conservation, safety and environmental protection .Not only fine control of the entire process to improve the conversion rate, prevent side reactions, increase dehydration effect, to reduce the product of inorganic salts, non sulfonated substances and water and other substances ,but also we should make full use of advanced production equipment, innovative technical means and intelligent control methods to further improve product quality, reduce production costs, strengthen the safety protection function of powder materials, and reduce environmental pressure.
