(under subclass 155) Apparatus which is also provided with means to pass a gas through or in contact with the liquid.
(1) Note. The gas contacting means may or may not cause gas to separate from the liquid.

95, Gas Separation: Processes,
159+, for processes of liquid contacting and degasifying liquid by stripping with a gas, and subclasses 245+ and 263+ for other processes of degasifying liquid with the use of a stripping gas.
261, Gas and Liquid Contact Apparatus, appropriate subclasses for apparatus for degasifying liquid (e.g., deaerating feed water heater, etc.) wherein the liquid is merely contacted with a gas in a chamber or space for deaeration thereof. If apparatus for degasifying liquid by contact with a gas has other means to cause gas separation of the liquid with gas entrained therein, of the separated gas, or of the separated liquid, then the apparatus is classified in Class 96. See section III of this class for an amplification of the line between these two classes.
