The Gas Station Device Of 100 ¡Á 10 ~ 4m ~ 3 / D Dehydration Process Design And Analysis

Natural gas is a kind of mixer which is made of little nonhydrocarbon gas and hydrocarbon gas with much low molecular saturated hydrocarbon. The natural gas which as well-flow content is always saturated by water, we must remove the water to some degree for meeting the gas water dew point requirement. Dehydration is a part of treatment contents, the usual dehydration methods are low temperature separation method, solvent absorption method and solid adsorption method, etc, the TEG dehydration technology of solvent absorption method is applying widely. According to the material gas conditions and dehydration requirements of the natural gas station yard, the article adopts the TEG dehydration technology method and stripping regeneration by considering the technology requirements and economic effects, then it uses the software HYSYS simulate process calculation. Selecting the TEG dehydration technology parameters and estimating the equipments size, the article designs the dehydration process flow and equipments which accord with the dehydration requirements of material gas, the conditions of product gas and the criterions of dehydration designing. It analyses the technology methods and parameters detailedly to validate the rationality of the dehydration technology designing in the article.
