As the content of H2S in the feed natural gas is increasing,which brings out problems that the deterioration rate of TEG solution is speeding up and the corrosion rate of the plant is aggravating.

Based on dehydration principle and technological process of triethyleneglycol dehydration device, this paper has analyzed and studied those questions appearing in the operation course of the devices and has proposed the corresponding measures for preventing or settlement.

The methods that determinated the triethyleneglycol content of triethyleneglycol mixtures by a gas chromatograph were studied.

Application of TEG cleaning to polyester plant;

INFLUENCE OF CONTAMINATIONS ON DEHYDRATION AND FOAMING PERFORMANCE FOR TEG;

STUDY ON THE REASON OF TEG VITIATION AND ITS RECYCLING TECHNOLOGY;

Determination and correlation of liquid-liquid equilibrium data for the ternary system of toluene-n-heptane-tetraethylene glycol and triethylene glycol;

Dehydration of air containing water vapor,which simulated wet natural gas,was studied by means of rotary packed bed(RPB) with triethylene glycol(TEG) as absorbent.

Gas-liquid equilibrium data for water - triethylene glycol - methyl chloride ternary system were measured in an equilibrium cell at 0.
