TRI ETHYLENE GLYCOL

Description

TEG is produced as a byproduct in the manufacture of MEG. 
TEG is a colourless liquid with a high boiling point. It is most hygroscopic in nature, amongst Mono & Diethylene Glycols. TEG is miscible with water,  alcohol , ether , acetone but is insoluble in benzene and its homologues. TEG is a stable non corrosive chemical with a high flash point.
TEG finds end use in Natural Gas Dehydration , Plasticizers , Conditioning agents etc.
At normal temperature and pressure , TEG can be easily transported in Mild steel tankers , internally coated with an epoxy paint.
Similarly, TEG can be stored in MS containers lined with baked phenolic resin / air drying epoxy phenolic resin or vinyl resin. It is advisable to store TEG in a cool , dry place with good ventilation - away from heat, sparks or flames.
Care should be taken to prevent TEG from mixing with strong acids , bases and oxidising materials.

 APPLICATIONS :

1. Natural Gas Dehydration: Hygroscopic nature of TEG is put to use in dehydration of natural gas. TEG is contacted counter currently with natural gas in a packed or bubble tray to remove moisture from natural gas. TEG is subsequently regenerated for reuse by stripping it of its water content. 2.

2. Plasticizer:TEG can be effectively used as a plastisizer for Vinyls, nitro cellulose, safety glasses. Diesters of TEG gives good low temperature properties and smooth film finishes.
3. Conditioning Agent
The affinity of TEG for water is used advantageously in the manufacture of adhesives or pastes to eliminate shrinkage, curling and brittleness.
