| 摘 要： | 在栲胶脱硫生产过程中除了主反应外,同时还伴随Na2S2O3,Na2SO4,NaSCN及NaHCO3等盐类生成的副反应.这些副产物的生成会影响栲胶脱硫液的性质,并最终影响整个脱硫循环工艺的稳定.为了避免这些影响,从表面张力、黏度和密度三个方面分析了Na2S2O3,Na2SO4,NaSCN和NaHCO3四种栲胶脱硫工艺的副产物对栲胶脱硫溶液的影响.结果表明,副产物的积累可以引起脱硫溶液表面张力的下降以及溶液黏度和密度的增加,从而引起脱硫工艺中操作条件的改变,最终影响整个系统的脱硫效率.

| Abstract: | There are main reactions in the process of tannin extract desulfurization production,however,side reactions which generate many salts(such as Na2S2O3,Na2SO4,NaSCN,NaHCO3,and so on)are inevitable.These by-products will influence the qualities of desulfurization solution of tannin extract and the stabilization of desulfurization technology.We made studies for the sake of effect.The effect of Na2S2O3,Na2SO4,NaSCN,NaHCO3,in desulfurization solution of tannin extract on desulfurization solution was investigated ... |
