摘要：

This paper compares three methods for natural gas dehydration that are widely applied in industry: (1) absorption by triethylene glycol, (2) adsorption on solid desiccants and (3) condensation. A comparison is made according to their energy demand and suitability for use. The energy calculations are performed on a model where 10(5) Nm(3)/h water saturated natural gas is processed at 30 degrees C. The pressure of the gas varies from 7 to 20 MPa. The required outlet concentration of water in natural gas is equivalent to the dew point temperature of -10 degrees C at gas pressure of 4 MPa.
