Abstract: A system for collecting a sorbate gas from a sorbent is disclosed, including a regeneration vessel enclosing a sorbent having a sorbate gas, a liquid water supply heated to a first temperature, and a heat pump with a condenser. The heat pump is also in contact with the water supply. Heat is removed from the condenser and used to heat the water supply to the first temperature. The system includes a compressor coupled to the condenser. The sorbent within the vessel is placed in contact with water vapor at the first temperature. The water vapor coming into contact with the sorbent causes sorbate gas to be released, forming a mixture including sorbate and water gases, raising the pressure. The vapor mixture is removed and cooled by the condenser, where a portion is condensed into water that is returned to the supply. The remaining mixture is compressed into a product gas.

Abstract: A system and method for the efficient collection of CO2 is disclosed. The system includes a subsystem having a condenser and a vaporizer, and a plurality of vessels each having a sorbent and configured to transition between gas collection, gas recovery, and heat recovery phases. The gas collection phase includes the sorbent absorbing CO2. The gas recovery phase has N stages, the vessels releasing a product gas and receiving vapor causing captured CO2 to desorb. The first (N?1) gas recovery stages include the vessel coupled to the subsystem at a downstream pressure and a vessel in the heat recovery phase at an upstream pressure. The Nth gas recovery stage includes the vessel coupled to the condenser at the downstream pressure and the vaporizer at the upstream pressure. The heat recovery phase has (N?1) stages, each including the vessel being coupled to a vessel in the gas recovery phase.

Abstract: A device, method, and system for CO2 capture is disclosed. The method includes receiving a process vapor including water and CO2 into a vessel at an intake pressure, the vessel having a desiccant and a CO2 sorbent material. The method includes passing the process vapor through the desiccant and sorbent, the desiccant absorbing the water resulting in a dry vapor, the sorbent absorbing CO2 from the dry vapor resulting in a CO2-lean dry vapor. The method includes discontinuing the process vapor, desorbing the water from the desiccant by at least one of reducing pressure downstream from the desiccant to below the intake pressure and increasing a temperature of the desiccant, desorbing the CO2 from the sorbent by placing the desorbed water in contact with the sorbent, removing the desorbed CO2 through the product outlet as a product stream, and desorbing a remaining water from the desiccant and the sorbent.

Abstract: An enhanced capture structure is disclosed, including a sorbent structure having a CO2 sorbent material. The capture structure also includes a plurality of barriers extending outward from the sorbent structure, each sized and positioned such that as an airflow passes along the sorbent structure, a high pressure region forms proximate the sorbent structure on a first side of the barrier facing into the airflow and a low pressure region forms proximate the sorbent structure on a second side of the barrier facing away from the airflow. The barriers on one side of the sorbent structure are staggered with respect to barriers on the other side such that a plurality of high and low pressure regions are formed, each high pressure region being formed opposite a low pressure region on the other side of the structure, creating a pressure differential that promotes CO2 mass transfer into the sorbent material via convection.

Abstract: A process and apparatus for the on-site delivery of a gas having improved purity to from a container filled with liquid under pressure and integrated with a purifier. In the process a portion of the liquid is converted to vapor by reducing the pressure in the container and expanding the thus formed vapor through a pressure reducer generating refrigeration. The cooled vapor is warmed against incoming vapor prior to exit from the purifier.

Abstract: A system for the supply and delivery of a high or a ultrahigh purity (UHP) carbon dioxide product stream to at least one process tool within a manufacturing facility and method comprising same is disclosed herein. In one embodiment, the system is comprised of the following sub-systems: a carbon dioxide source, a carbon dioxide delivery system, and the point of use (POU) containing at least one process tool.

Abstract: Method for the purification of a volatile metal hydride comprising obtaining a volatile metal hydride feed containing one or more acidic impurities, one of which is a sulfur-containing impurity; contacting the feed with an alkaline material and reacting at least a portion of the sulfur-containing impurity with the alkaline material to remove a portion of the sulfur-containing impurity from the feed and provide an intermediate purified material; and contacting the intermediate purified product with an adsorbent material to remove at least a portion of the sulfur-containing impurity from the intermediate purified material and provide a purified volatile metal hydride product.
