在高剪切分散乳化机的作用下,对影响FCC汽油液-液脱臭的4个主要因素进行正交试验并进行了极差分析和方差分析,结果表明4个因素对脱臭效果影响的显著性为碱浓度>剂油比>催化剂浓度>搅拌速度.由于高剪切分散乳化机良好的混合效果,碱浓度即使降至1 wt%后,仍然可以达到较好的脱臭效果;而且当H2S浓度不大于20μg·g-1时,采用该方法脱臭后的油样,其铜片腐蚀实验合格,因此该工艺可以大大减少碱液的消耗,降低对环境的污染.当剂碱中混有苯酚时,博士试验合格时的硫醇含量较高,分析其原因可能由于苯酚对硫醇的抽提作用或是在氧化过程中,苯酚被氧化成过氧化物从而对博士试验结果产生影响.

@@@@The affecting factors in sweetening process, such as the stirring speed, the ratio of oil to aqueous solution containing catalyst and alkali, as well as the alkali concentration and catalyst had been inspected by mixing the oil with aqueous solution containing alkali and catalyst using a high sheer-dispersing emulsifier. The results showed that the influence of the concentration of alkali was most prominent, next was the ratio of oil and solution of catalyst and alkali which was much prominent than the concentration of catalyst, and the effect of the speed of stirring could be ignored. The content of mercaptans in oil could satisfy the requirement even when the alkali was diluted to 1%, and as long as the concentration of H2S was less than 20μg/g, the test of copper strip corrosion would be qualified. The reason that the doctor test was qualified even with high concentration of mercaptans maybe because of the phenol dissolved in petroleum ether was oxidized to peroxide.
