    摘要： A gas processing facility for the separation of fluids is provided. The facility includes co-current contactors placed in series. Each co-current contactor receives a gas stream that includes a non-absorbing gas such as a hydrocarbon gas or nitrogen. The gas stream also includes an acid gas or other contaminant. Each co-current contactor also receives a liquid solvent stream. The co-current contactors then each release a sweetened gas stream and a gas-treating solution. In one processing direction, the contactors are arranged to deliver progressively sweetened gas streams. In the opposite processing direction, the contactors are arranged to deliver progressively richer gas-treating solutions. In one aspect, the facility includes at least a first co-current contactor, a second co-current contactor and a final co-current contactor. However, any number of at least two co-current separators may be employed. Methods and processes for separating a gas stream are also provided.

    摘要： A cryogenic distillation tower is provided for the separation of a fluid stream containing at least methane and carbon dioxide. The cryogenic distillation tower has a lower stripping section, an upper rectification section, and an intermediate spray section. The intermediate spray section includes a plurality of spray nozzles that inject a liquid freeze zone stream. The nozzles are configured such that substantial liquid coverage is provided across the inner diameter of the intermediate spray section. The liquid freeze zone stream generally includes methane at a temperature and pressure whereby both solid carbon dioxide particles and a methane-enriched vapor stream are formed. The tower may further include one or more baffles below the nozzles to create frictional resistance to the gravitational flow of the liquid freeze zone stream. This aids in the breakout and recovery of methane gas. Additional internal components are provided to improve heat transfer and to facilitate the breakout of methane gas.

    摘要： A system for removing acid gases from a raw gas stream is provided. The system includes a cryogenic distillation tower. The cryogenic distillation tower has a controlled freezing zone that receives a cold liquid spray comprised primarily of methane. The tower receives and then separates the raw gas stream into an overhead methane gas stream and a substantially solid material comprised of carbon dioxide. The system includes a collector tray below the controlled freezing zone. The collector tray receives the substantially solid material as it is precipitated in the controlled freezing zone. The system also has a filter. The filter receives the substantially solid material and then separates it into a solid material comprised primarily of carbon dioxide, and a liquid material comprising methane. The solid material may be warmed as a liquid and sold, while the liquid material is returned to the cryogenic distillation tower.
