of sour gas from offshore. The gas is brought ashore via a diameter, pipeline. The plant separates methanol (used for hydrate inhibition), water and condensate from the gas stream. The gas is sweetened with an amine solvent to remove sulphur compounds down to 3.3 ppm hydrogen sulphide and 35 ppm mercaptans. The hydrocarbon dew-point of the gas is reduced by mechanical refrigeration to a quality suitable for pipeline transportation. The treated gas is piped to Connah's Quay Power Station at 30 bar via a diameter, pipeline. Any gas surplus to the fuel requirements of the power station is further treated and delivered to the Burton Point terminal of the
