Raw gas preparation

Gröger & Obst GO-MO 3

Preparation of raw gas for continuous gas analysis (process analysis).

The GO-MO 3 measurement gas processing system includes a permeation dryer, a fine-particle filter, and a measurement gas pump.

The gas quantity can be freely adjusted within the range of 50 to 120 l/h using a flow regulator.

All components are housed in a plastic enclosure designed for wall mounting.

The connections for the mesurement gas input and output are located on the top of the housing and marked EIN and AUS (= IN and OUT).

For the 230 V AC mains connection, there is a cold-appliance connector with a micro fuse located on the left side. A suitable connection cable is included in the accessory package.

How the permeation dryer works

This device consists of a tube made of a selectively permeable plastic membrane enclosed by another tube. A carrier gas (usually ambient air) flows through this outer tube in the opposite direction to the measurement gas stream.

Water molecules diffuse through the inner tube from the measurement gas into the carrier gas and are carried away by the carrier gas flow.

To avoid disrupting or completely stopping this water transport, the measurement gas must not contain any particles, aerosols, or water in liquid form (droplets). We therefore recommend installing the GO-MO 1 measurement gas processing unit or another cooler upstream to reliably prevent this
