磷霉素钠合成工艺过程中的酯化反应产生大量的HCl气体,原利用真空将HCl气体逐级导入装满水的陶瓷坛子进行收集,效率低,能耗高,而且数量多占地面积大,危险源数量多不易于控制,存在安全隐患。现采用降膜吸收装置用于盐酸收集,占地面积小,提高了生产能力,达到节能创效的目的。
Fosfomycin sodium synthesis process of the esterification reaction to produce a large amount of HCl gas, the original use of vacuum HCl gas gradually introduced into a ceramic jar filled with water collection, low efficiency, high energy consumption, and a large number of large area , The number of dangerous sources is not easy to control, there are security risks. Is the use of falling film absorption device for hydrochloric acid collection, covers an area of small, increased production capacity, energy-saving effect to achieve the purpose.
