摘要
介绍了喷雾法生产石油磺酸盐的研究情况。根据石油组分的特点,采用喷雾磺化技术大幅度增加了石油组分与三氧化硫的气液接触面积,使得磺化效率得到了很大的提高,磺化反应接触时间从几小时缩短到几十秒,减少了石油组分过磺化现象的发生,小试研究结果表明,与传统釜式磺化技术相比,采用改造后的喷雾磺化工艺使得石油磺酸盐的收率提高了3%以上,酸性油收率提高10%以上,酸渣收率降低35%以上,可实现连续化生产,并为工业化应用提供参考。
Technology for production of petroleum sulfonate via spray method was introduced. Based upon the characteristics of the petroleum fraction,the adoption of spray sulfonation technology increases the contacting surface area between the petroleum fraction and SO3 substantially and results in a great improvement of the sulfonation efficiency. Contacting time for sulfonation reduces from several hours to several ten seconds and thus reduces the happening of over- sulfonation. Results of laboratory tests showed that as comparing with the conventional reaction kettle sulfonation,the spray sulfonation causes more than 3% increase of yield of the petroleum sulfonate and more than 10% increase of yield of the raffinate oil; while the yield of the acid residue decreases for more than 35%. Continuous process can be realized and the laboratory test results can be used as reference for industrial operation.
