摘要： A process for the removal of water from gas which comprises an absorption step of bringing a gas saturated with water vapor into gas-liquid contact with a water-lean absorbing liquid comprising a water absorbing liquid having a cloud point temperature above the freezing point of water whereby water vapor present in the gas is absorbed into the water-lean absorbing liquid at a temperature below its cloud point to produce a refined gas having a reduced water vapor content and water-loaded absorbing liquid. A regeneration step is provided in which the water-loaded absorbing liquid is heated to above the cloud point temperature of the absorbing liquid whereby the water-loaded absorbing liquid separates into a water-rich phase and an absorbing liquid-rich phase and the absorbing liquid-rich phase is cooled to a temperature below its cloud point prior to recycling the absorbing liquid-rich phase for use as water-lean absorbing liquid in the absorption step.

摘要翻译：一种从气体中除去水分的方法，该方法包括吸收步骤：使含饱和水蒸汽的气体（1）与包含具有浊点温度的吸水液体的贫水吸收液体（3）气液接触高于水的冰点，由此气体中存在的水蒸气在低于其浊点的温度下被吸收到贫水吸收液体中，以产生具有降低的水蒸汽含量的精制气体（4）和水负载吸收液体（ 5）; 和将吸水性吸收液（5）加热至吸收液的浊点温度以上的再生工序，从而使吸水性吸收液分离成富水相（7）和吸收富液相（ 8），并在吸收步骤中再循环富吸收液体相用作贫水吸收液体（3）之前将吸收富液相冷却至低于其浊点的温度。
