Class Information
Number: 96/179
Name: Gas separation: apparatus > Degasifying means for liquid > Defoaming means > Having flow-through foam restrictor or eliminator (e.g., screen, etc.)
Description: Apparatus which is equipped with a porous screen or filter to remove foam (i.e., entrained gas bubbles) from the liquid passing therethrough by (a) physically excluding the foam or (b) breaking a liquid film surrounding entrained gas (i.e., foam) and liberating the entrained gas.
