At the rig, natural gases are nearly always saturated with water. When water-saturated natural gas flows in a pipeline the following problems can occur:
Water can collect in pipelines and increase the pressure drop and/or cause slug flow.
Water can freeze and/or form solid hydrates, consequently reducing the gas flow or plugging the line.
Acid gases (H2S & CO2) dissolve in free water and will cause severe corrosion.
Ideally dehydrating the gas by heating, chemical addition, solid desiccant and membrane dehydration mitigates these problems and improves safety. GENERON offers the following efficient and cost effective solutions for process gas:
Membrane Dehydration
In GENERON® membrane gas dehydration systems, the feed gas is filtered to remove any trapped liquids and aerosols. The gas then enters the GENERON® membrane filters, where the H2O, CO2 and H2S permeate through the membrane. The non-permeated gas, mainly CH4, remains at process pressure and becomes the product gas.
Membrane Dehydration
Ideal Pressure: Up to 1,000 psig
Ideal Temperature: < 160°F / 71°C
Flow Rate: 0.01 to 500 MMSCFD
Dew Point: -40°F / -40°C
