NATURAL GAS DRIER Russian patent published in 2004 - IPC

FIELD: absorption drying of natural gas.

SUBSTANCE: proposed natural gas drier is made on base of diethylene glycol including borax, foam suppressor, type 139-282 on base of silicon-organic liquids and anti-foamer; anti-foamer contains laprol and potassium carbonate, disodium phosphate and benzotrioazole at the following ratios of components, mass-%: borax, 0.3-1.0; potassium carbonate, 0.1-0.3; disodium phosphate, 0.5-1.2; benzotriazole, 0.05-0.1; laprol, 0.001-0.1; foam suppressor, type 139-282, 0.001-0.1; the remainder being diethylene glycol. Reduction of corrosion of field equipment in gas phase to 0.02-0.00493 mm/year and to 0.009-0.00015 mm/year in liquid phase.

EFFECT: enhanced efficiency.
