DEFINITION

Classification: 95/172

By reduction of pressure (e.g., flashing, etc.):

(under subclass 156) Process in which the gas is removed from the contact liquid by decreasing the pressure acting on the contact liquid.

SEE OR SEARCH THIS CLASS, SUBCLASS:

160+, for processes of liquid contacting and degasification of liquid by stripping with gas in which there is reduction of pressure.

192, and 208, for separation of liquid from contact liquid by reduction of pressure.

247+, for plural successive liquid degassing treatments which include reduction of pressure.

266, for degasification of liquid by reduction of pressure.

SEE OR SEARCH CLASS 96, Gas Separation: Apparatus,

193+, for degasifying means for liquid of the pressure reducing type.
