Comparison of Gas Dehydration Methods based on Energy Consumption
KINIGOMA, B.S. & ANI, G.O.
Abstract
This study compares three conventional methods of natural gas (Associated
Natural Gas) dehydration to carry out the dehydration process and suitability of use on the
basis of energy requirement. These methods are Triethylene Glycol (TEG) absorption, solid
desiccant adsorption and condensation. Analyses performed were based on dehydration of
Natural Gas saturated with 103Nm3/h water content at a temperature range of -10° C to 30°C,
and gas pressure variation between 7MPa and 20MPa. This analysis and study showed that
energy required for all three processes decreases with increase in pressure, but condensation
dehydration requires the least energy at high pressures. Results obtained shows that, both at
high pressures and low pressures, TEG dehydration is most suitable and in cases where very
low Tdew is required, solid desiccant adsorption is preferable. In conclusion, the findings in
this paper will aid natural gas process design engineers to decide on what method to use base
on energy consumption and on the physical and chemical properties of the final products.
