DEFINITION

Classification: 95/206

And separation of liquid from contact liquid:

(under subclass 149) Process in which a 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.).
