Transcript of ETHYLENE GLYCOL PLANT DESIGN

APPLICATIONS OF ETHYLENE GLYCOL
Polyester fibers & Fabric Industry

PET resins used in bottling

Antifreeze & Coolant


Ethylene glycol was first prepared in 1859 by the French chemist Charles-Adolphe Wurtz. It was produced on a small scale during World War I, for use as a coolant and as an ingredient in explosives.

Capacity :
89.000 Ton/Year MEG
Production Tecnology :
In the Aliağa Complex entegrated
Ethylene Oxide / Ethylene Glycol Plant is "SHELL’s direct oxidation " process.
Products :
Mono-ethylene Glycol (MEG) Di ethylene Glycol (DEG)
End Uses :
Antifreeze, Polyester fiber, PET bottles, Textile Products and Explosive materials.
Price of EG :
1000-1200 $/t

ETHYLENE GLYCOL PLANT DESIGN
CAPACITY:

REACTIONS
First reaction:

CH 2 = CH 2 + 1/2 O 2 C2H4O

- Reaction caries out at 17,4 kg/cm 2 and 230 °C in fixed bed that has silver catalyst.
- Exothermic reaction.  
- Product are taken from the bottom of the
reactor at 240 0 C – 260 0 C
- Conversion is %2,5

2 C2H 4O + H2O CH 2OH - CH 2 OH + 22 kg.cal /gr. mol


Monoethyleneglycol ( MEG )
 
 
C2H 4O +MEG HOCH2–CH2-O-CH2–CH2OH +25 kg-cal/gr.mol


Diethyleneglycol ( DEG)

 
 
C2H 4O +DEG HOCH2-CH2-O-CH2-CH2-O-CH2-CH2OH +24 kg- cal/g.mol



Triethyleneglycol ( TEG)
