DEFINITION

Classification: 95/188

After separation of liquid from contact liquid:

(under subclass 187) Process in which the contact liquid is recycled or reused after another liquid constituent is removed from the contact liquid.

(1) Note. The liquid removed from the contact liquid may have been originally present as liquid particles entrained in a gas, or the liquid removed may have been originally present as vapors as part of a plurality of gases, in which case the vapors would have condensed to liquid because of the liquid contact.

(2) Note. In order for a patent to be placed here, the vapors sorbed by a liquid from a plurality of gases and removed from the liquid must be normally liquid at a temperature of 0 deg.C and a pressure of 760 mm Hg and the vapors must have condensed to liquid (e.g., methanol (CH3OH), ethanol (C2H5OH), etc.).

206+, for separation of a liquid constituent from the contact liquid without recycling or reusing the contact liquid.
