    Abstract: A method and system are described for heating natural gas in a station, such as a City Gate station. Natural gas from the field is generally transported via supply line at high pressure to the various distribution networks necessary for delivering the gas. However, before the natural gas can enter these distribution networks its pressure must be reduced to a usable level. City Gate stations employing pressure reducing (JT) valves are usually built for this purpose. The present invention provides a system and method for heating the natural gas, without combustion of the natural gas, by relying on the pre-existing pressure of the gas in the supply line along with particular equipment to provide heat to the gas passing through the station.

    Abstract: Novel maleimide copolymers have at least two monomeric units, a maleimide unit and a vinyl unit having a pendant group, the pendant group having two to twenty-one carbon atoms, at least one nitrogen atom and at least one oxygen atom. The copolymer has an average molecular weight between about 1,000 and about 6,000,000. Preferred maleimide copolymers include acrylamide/maleimide copolymers, N-vinyl amide/maleimide copolymers, vinyl lactam/maleimide copolymers, alkenyl cyclic imino ether/maleimide copolymers, and acryloylamide/maleimide copolymers. The substantially water soluble maleimide copolymers are useful for inhibiting the formation of clathrate hydrates in a fluid having hydrate-forming constituents by reducing the rate of nucleation, growth, and/or agglomeration of gas hydrate crystals in a petroleum fluid stream, thereby inhibiting the formation of a hydrate blockage in the pipe conveying the petroleum fluid stream. The inhibitor can be used conveniently at low concentrations, for example in the range of from about 0.01% to about 5% by weight of the water present in the oil or gas stream, to effectively treat a petroleum fluid having a water phase.
