摘要： The disclosure includes a method for separating a feed stream in a distillation tower may comprise maintaining a controlled freeze zone section in the distillation tower that forms solids from a feed stream, wherein the controlled freeze zone section includes one or more internally disposed elements and a controlled freeze zone wall having an internal wall surface inside of the distillation tower, modifying at least one of the internally disposed elements, the internal wall surface, or both with a treatment mechanism that includes at least one of (a) removing portions of the internal wall surface and (b) applying a coating surface, introducing the feed stream into the controlled freeze zone section, forming the solids from the feed stream in the controlled freeze zone section, and at least one of preventing and destabilizing adhesion of the solids to the internal wall surface with the treatment mechanism.

摘要： A method of removing impurities from a natural gas stream. A selective solvent is provided that absorbs a first impurity at a first rate and a second impurity at a second rate that is slower than the first rate. The solvent is cooled to a temperature below 60° F. to provide a cooled solvent. The cooled solvent is contacted with the natural gas stream, thereby generating a rich solvent that includes the first impurity. The rich solvent is removed from the natural gas stream, wherein an amount of the first impurity remaining in the natural gas stream is below a sales gas requirement.

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 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 and a system for feeding a feed gas including methane (CH4) and carbon dioxide (CO2) to a cryogenic distillation column are provided herein. The method includes flowing a freeze zone CO2 vapor stream into a freezing section of the column to produce an overhead stream that exits the column. The method includes heating the overhead stream via a heating component to reduce or prevent solidification of the CO2 in the overhead stream.

摘要： Provided are apparatus and systems for performing a swing adsorption process. This swing adsorption process may involve passing streams through adsorbent bed units to treat the feed stream to form a stream that complies with nitrogen rejection specifications. The process may involve using at least a portion of the nitrogen rejection process product streams as a purge for the swing adsorption process.
