ABSTRACT:
A simplified, low-cost method of treating pressurized, moving natural gas streams in order to control problems created by entrained water in the gas is provided which facilitates downstream treatment of the gas and increases product yields by lessening the formation of oil and water emulsions and hydrates which can coat and clog processing equipment, while also minimizing corrosion of the latter. The method involves introduction of an agent into the moving gas stream which includes a polymer having recurring quaternized pyridinium groups therein for controlling the emulsion, hydrate and corrosion problems; the method is especially effective when the entrained water contains surfactants, detergents, soaps, and the like. In preferred forms a low molecular weight copolymer of styrene and 2-vinyl pyridine dispersed in water is atomized into the gas stream adjacent cooling and scrubbing stations. The present method finds particular utility in connection with natural gas products plants, although other types of gas-processing facilities can also be served.
