Gas Separation  [ Return towards  Chemicals & Petrochemicals  ]

We supply the three gas separation technologies (cryogenics, adsorption and membranes) and all the know-how to combine them.

For example, MEDAL gas separation membranes are used in the petrochemical industry to recover and recycle the hydrogen contained in purge gases in synthesis loops and also for adjusting the H2/CO ratio by eliminating excess hydrogen by means of permeators :

Adjustment of H2/CO ratio
Purge current for ammonia synthesis
PSA off-gas
Purge gas for methanol synthesis
Ethylene off-gas and steam cracker gas
Hydrodealkylation recycling gas
Extraction of H2 from polyolefin reactor purge gas

Our MEDAL membranes are easy to install and use. Since 1987, we have sold around 90 commercial installations worldwide.
