Abstract: The disclosure provides a method for separating components of a gas. A feed gas stream is cooled in a first vessel. The feed gas stream includes methane, water, carbon dioxide, and Natural Gas Liquids. The feed gas stream is cooled in a first vessel. A portion of the water condenses to form a primary liquid stream, resulting in a first depleted gas stream, which is cooled in a second vessel. A portion of the NGLs condense to form a secondary liquid stream, resulting in a second depleted gas stream, which is cooled in a condensing exchanger. A first portion of the methane condenses to form a liquid methane stream, resulting in a third depleted gas stream, which is cooled in a third vessel. A portion of the carbon dioxide condenses, desublimates, or condenses and desublimates as a final product stream, also resulting in a fourth depleted gas stream.

Abstract: In a first aspect, the disclosure provides a method for removing a component from a gas stream. A carrier gas stream is cooled by direct contact with a dehydrating solution stream. The dehydrating solution stream removes a portion of water present in the carrier gas stream and produces a dry gas stream and a wet solution stream. A portion of the component is removed from the dry gas stream by direct contact with a cold contact liquid stream. A depleted gas stream and a slurry stream are produced. Removing the portion of the component may include desublimating, freezing, condensing, depositing, or a combination thereof of the portion of the component out of the dry gas stream as a solid product. The slurry stream may include the solid product and a contact liquid. The solid product is separated from the contact liquid, producing a substantially pure solid product stream and the cold contact liquid stream.

Abstract: An air-sparged hydrocyclone for separating a vapor from a carrier gas is disclosed. The cyclone comprises a porous sparger covered by an outer gas plenum. A cryogenic liquid is injected to a tangential feed inlet at a velocity that induces a tangential flow and a cyclone vortex in the air-sparged hydrocyclone. The carrier gas is injected into the cyclone through the porous sparger. The vapor dissolves, condenses, desublimates, or a combination thereof, forming a vapor-depleted carrier gas and a vapor-enriched cryogenic liquid. The vapor-depleted carrier gas is drawn through a vortex finder and the vapor-enriched cryogenic liquid is drawn through an apex nozzle outlet. In this manner, the vapor is removed from the carrier gas.

Abstract: A method and device for transferring solid particles between zones of different pressures is disclosed. A rotating annular disk spans a pressure barrier and comprises a radial piston cylinder connecting the exterior with the interior. A piston is disposed within the radial piston cylinder comprising a proximal end and distal end, the distal end comprising a cam follower. A stationary closed cam device is located within the interior portion comprising an internal cam profile. The cam follower is in contact with the internal cam profile. As the disk rotates, the cam follower tracks the cam profile causing the piston to move rectilinearly through the radial piston cylinder. As the radial piston cylinder aligns with a solids source, the piston retracts, providing a cavity into which the solid particles fall. As the radial piston cylinder aligns with a solids receptacle the piston returns, ejecting the solid particles into the solids receptacle.

The solids outlet is adjacent to a solids receptacle, the solids receptacle being at a second ambient condition. The piston comprises a hollow. The piston traverses back and forth across the piston chamber such that the hollow is moved alternately adjacent to the solids inlet and the solids outlet. The solid particles pass into the hollow as the hollow is adjacent to the solids inlet, and pass out of the hollow as the hollow is adjacent to the solids outlet.
