Ethylene Glycol Production

 

Ethylene Glycol production

 

The principal by-product is diethylene glycol and higher glycols (i.e. triethylene glycols). The formation of these higher glycols is inevitable because ethylene oxide reacts faster with ethylene glycols than with water.

Plants maintain a high rate of conversion by using excess amounts of water to promote ethylene glycol production selectivity. 

The excess water is removed by and recycled in a series of evaporators, and the ethylene glycol is refined by vacuum distillation.

 

Contamination Control

 

• Contaminants, in both solid & semi-solid form, are introduced into the production process with the incoming raw material water, a result of side products generated during the hydrolysis reaction

• Controlling the contaminant level of fluids used in ethylene glycol production will Optimize Productivity

• Ensures final product meets specification
