具有多个 OH 基团的醇类可以产生聚合反应。与甘油等天然醇类不同,醇类是通过发酵含淀粉或糖的基础物质而获得的。
甲醇和乙醇等短链式醇类通过蒸馏的方法进行浓缩。蒸汽挥发性较低的长链式醇类可通过降膜蒸发装置进行浓缩。分离机通常配有洗涤塔,以通过蒸汽相态将产品损失降到最低。
在蒸馏装置中浓缩的醇类大多数是甲醇和乙醇。异丙醇和正丁醇在蒸发装置中进行浓缩。

Jet pumps, also referred to as ejectors, are devices for the conveyance, compression or mixing of gases, vapors, liquids or solids and for the production of vacuum in which a gaseous or liquid medium serves as the motive force.
Mixing is a vital process in the production of a diverse range of products in a wide range of industries. Based on our extensive experience and technological know-how, GEA offers a variety of batch, continuous and in-house custom designed mixing solutions for unique applications that meet specific customer needs.
热力蒸汽再压缩采用蒸汽喷射来提高进入设备的蒸汽温度等级。然后,这些加压蒸汽流的冷凝可用于加热或蒸发温度较低的工艺流体。因此,会最大程度地降低蒸汽消耗。
