DEFINITION

Classification: 95/160

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

(under subclass 159) Process in which the pressure acting on the contact liquid is decreased.

(1) Note. The pressure reduction may be used in a separate step in order to remove gas from the contact liquid in addition to the step of removing gas from the contact liquid by stripping with gas, or the pressure reduction may be used in order to aid the removal by stripping with gas.
