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。

MVR / TVR 加热蒸馏装置
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。

Fueling the circular economy in shipping
Ports now compete not just on logistics, but on sustainability. At Greece’s Piraeus port, an advanced processing and recovery facility recycles ship waste oil into fuel. Equipped with GEA’s high-performance centrifuges, it sets a new benchmark for state-of-the-art, environmentally responsible port operations.
