Chemistry gas permeable holder
WebThat main function of biogas holders is to control the gas, both upstream and downstream, by applying an adequate driving force (pressure) to carry the biogas around the system at the required pressure and flow rate. It is also, crucially, the device that provides the signals to equipment, to turn them on or off, and to raise signals or alarms.

The permeation of films and membranes can be measured with any gas or liquid. One method uses a central module which is separated by the test film: the testing gas is fed on the one side of the cell and the permeated gas is carried to the detector by a sweep gas. The diagram on the right shows a testing cell for films, … See more In physics and engineering, permeation (also called imbuing) is the penetration of a permeate (a fluid such as a liquid, gas, or vapor) through a solid.
