DEFINITION
Classification: 95/46
Degasification of liquid:
(under subclass 45) Process in which gas is separated from a liquid by selective diffusion of the gas through a substantially solid barrier.

210, Liquid Purification or Separation,
640, for processes of separating a constituent from a liquid by selective diffusion of the constituent through a membrane or septum wherein the constituent is not initially present as a gas in the liquid and passes through the membrane or septum in vapor phase.
