Solvent absorption method often used as an absorbent material glycols

Solvent absorption method often used as an absorbent material glycols, having a hydroxyl group and an ether natural gas treatment processes  bond in the molecular structure of the glycol, to form hydrogen bonds with water, have a strong affinity for water,molecular sieve drying having a high dehydration depth.
Glycol dehydration in natural gas industry has been successfully applied are: ethylene glycol (EG), diethylene glycol (DEG), triethylene glycol (TEG) and tetraethylene glycol (TREG).  molecular sieves msds   Glycol gas dehydration is the first for diethylene glycol, due to restrictions by the regeneration temperature, poor liquid mass fraction is generally about 95%, dew point down low; while TEG regeneration easy, poor liquid mass fraction of 98% ~ 99%, with greater dew point depression and low operating costs, has been widely used.
