| 摘 要： | 栲胶法脱硫工艺比ADA法应用更广,更具优越性.为揭示这种优越性,采用表面张力仪和电导率仪分别对氧化栲胶水溶液和ADA水溶液的表面性质进行了研究.结果表明,氧化栲胶是离子型表面活性剂,可降低溶液表面张力,并强化硫化氢或空气的气液传质速率;而ADA溶液不具有这种性质,这是栲胶脱硫技术优于ADA法脱硫技术的原因之一.氧化栲胶溶液的临界胶束浓度为0.53g/L,该值可作为栲胶脱硫溶液中氧化栲胶含量的最小值.

| Abstract: | Comparing with ADA,the tannin extract desulfurization is more superior and applied widely in industry.In order to reveal the advantages,the surface properties of oxidized tannin extract and ADA aqueous solution are researched using surface tensiometer and conductivity meter.The results shows that the oxidized tannin extract is an ionic surfactant,which can reduce the surface tension of solution and intensify the gas-liquid mass transfer rate of hydrogen sulfide or air with solution.Howere,the ADA solution i... |
