合成高碱值石油磺酸钙清净剂的搅拌鼓泡釜工艺需外加水;而旋转填充床工艺中只需反应牛成水参与反应,即可达到碱值的要求,简化了工艺和控制过程.分析了2种反应器的特性.结果表明,强化了微观混合和传质的旋转填充床能快速生成细小、均匀的W/O型微乳液体系;通过溶解一消耗一再溶解一再消耗模式,能有效利用w/O型微乳液体系中的水核,需水量少;同时,旋转填充床使物料系统的含CO_2气率较均匀,生成的纳米CaCO_3粒子粒径小、分布窄,产品质量高.也指明r搅拌鼓泡釜反应器在混合分散和传质均匀性方面的相对不足.

High-TBN calcium sulfonate synthesis in stirred bubbling tank reactor needs more water to participate, while in rotating-packed bed (RPB) it needs only water formed in synthesis itself to reach TBN requirement, so that the process becomes simply and easily controlled, simultaneously.The characteristics of the two reactors were analyzed.The results showed that in RPB, micro-mixing and mass transfer were intensified, tiny and uniform W/O microemulsion was formed quickly; by the pattern of dissolve-deplete-redissolve-redeplete, the utilization of water core of W/O microemulsion was efficient, the amount of water needed in process was small; CO_2 was fairly well-distributed and approximately homogeneous in all RPB system, making diameter of the grown CaCO_3 nanoparticle smaller and uniform and the performance of detergent product better;in stirred bubbling tank reactor.The shortcoming in the micro-mixing and mass transfer uniformity of stirred bubbling tank process was also indicated
