Method and system for transporting and processing sour fluids

摘要

A method and system for transporting and processing sour gas are provided. The method includes collecting a sour gas at a collection location, which has an associated sweetening device, and delivering a solvent to the sweetening device from a regeneration device remote therefrom. The sour gas is treated at the collection location with the solvent in the associated sweetening device to form a sweetened gas and a sour gas-rich solvent. The sweetened gas is transported from the sweetening device to a gas processing plant remote therefrom, and the sour gas-rich solvent from the sweetening device is delivered to the regeneration device for regeneration therein.

主权项

1. A system comprising:
a plurality of collectors at a plurality of collection locations configured to collect sour gas wherein each collector is located at a site of a subsurface hydrocarbon reservoir; a plurality of sweetening devices, each one of the sweetening devices located at each one of the plurality of collection locations and fluidly connected to one of the plurality of collectors to receive the sour gas from the collector, the plurality of sweetening devices configured to treat the sour gas with a sour gas-lean solvent to form a sweetened gas and a sour gas-rich solvent; a regeneration device remote from the plurality of collection locations and configured to deliver the sour gas-lean solvent to the plurality of sweetening devices wherein the regeneration device is at least 0.62 mile (1 kilometer) from the plurality of collection locations; and a first common pipeline configured to transport the sweetened gas from the plurality of sweetening devices to a gas processing plant remote therefrom and deliver the sour gas-rich solvent from the plurality of sweetening devices to the regeneration device for regeneration therein; wherein the plurality of sweetening devices are spaced along the length of the first common pipeline.
