摘要： Disclosed techniques include a method of obtaining an enhanced oil recovery fluid from a hydrocarbon reservoir, comprising producing a hydrocarbon stream from the hydrocarbon reservoir, separating an associated gas stream from the hydrocarbon stream, and condensing at least a portion of the associated gas stream to obtain an enriched hydrocarbon fluid suitable for injecting into a liquid layer of the hydrocarbon reservoir to enhance recovery of hydrocarbons from the hydrocarbon reservoir.

摘要： A method of designing, constructing, and operating a hydrocarbon gas treatment plant is disclosed. A target hydrocarbon production range for a hydrocarbon gas meeting a required product specification is established. A cryogenic distillation column is designed and constructed with a vapor capacity to meet the target hydrocarbon production range. A variable feed refrigeration system is incorporated to cool an inlet feed of the hydrocarbon gas. The variable feed refrigeration system is designed to handle the target hydrocarbon production range and a wide range of contaminant concentrations in the inlet feed. A variable bottoms heating system is incorporated to handle heating duties associated with the wide range of contaminant concentrations in the inlet feed. A variable bottoms pumping system is incorporated to handle liquid flows associated with the wide range of contaminant concentrations in the inlet feed.

摘要： A cryogenic distillation tower for separating a feed stream. The tower includes a distillation section. A controlled freeze zone section is situated above the distillation section and forms a solid from the feed stream. The controlled freeze zone section includes a spray assembly in an upper section and a melt tray assembly in a lower section. The melt tray assembly includes at least one vapor stream riser that directs the vapor from the distillation section into liquid retained by the melt tray assembly, and one or more draw-off openings positioned to permit a portion of the liquid to exit the controlled freeze zone section. The portion of the liquid indirectly exchanges heat with a heating fluid. One or more return inlets return the portion of the liquid to the melt tray assembly after it has been heated in the heat exchanger.

摘要： A method of separating a feed stream in a distillation tower. Vapor is permitted to rise upwardly from a distillation section of the distillation tower. A feed stream is introduced into a controlled freeze zone section of the distillation tower, the controlled freeze zone section being situated above the distillation section. The feed stream is released above a level of a liquid retained by a melt tray assembly in the controlled freeze zone section. Vapor from the distillation section is directed into the liquid retained by the melt tray assembly. A solid is formed from the feed stream in the controlled freeze zone section.

摘要： A system and method for an intermediate pressure vessel to receive a purge in a cryogenic distillation column system. The vessel operates at an intermediate pressure to reduce solidification of the purge. The cryogenic distillation column receives a natural gas having methane and acid gas. The column discharges an overhead stream rich in the methane, and a bottoms stream rich in the acid gas. An overhead system receives the overhead stream, and discharges a vapor methane product, and a cooled liquid for reflux to the cryogenic distillation column.
