摘要： An apparatus for forming solid carbon dioxide blocks comprises a chamber with an internal cavity, a flow control valve including a variable area orifice, an actuator configured to control the area of the variable area orifice and a controller configured to vary the are of the variable area orifice while liquid carbon dioxide is being flashed to solid carbon dioxide snow through the flow control valve. A method of forming carbon dioxide blocks comprises the steps of varying the area of an orifice while flowing liquid carbon dioxide through the orifice under sufficient pressure to flash the liquid carbon dioxide to solid carbon dioxide snow.

摘要： Methods and systems of collecting carbon dioxide are disclosed. In one example, a method includes removing water from atmospheric air with a condenser and a desiccant material to produce dry air, adsorbing carbon dioxide to a material from the dry air, releasing the adsorbed carbon dioxide to a vacuum chamber, and transitioning the released carbon dioxide from a gas to a solid in the vacuum chamber.

摘要： The present disclosure provides systems for carbon capture in combination with production of one or more industrially useful materials. The disclosure also provides methods for carrying out carbon capture in combination with an industrial process. In particular, carbon capture can include carrying out calcination in a reactor, separation of carbon dioxide rich flue gases from industrially useful products, and capture of at least a portion of the carbon dioxide for sequestration of other use, such as enhanced oil recovery.

摘要： Described herein are methods, systems, and techniques relating to clathrate hydrate formation processes and, particularly, involving reactive metal nucleation substrates for promoting clathrate hydrate formation. The disclosed methods, systems, and techniques allow for improved nucleation rate and yield of clathrate hydrates. In some cases, the disclosed methods, systems, and techniques can also improve or reduce the amount of time needed for obtaining a given quantity of clathrate hydrate phase, for example, in desalination, gas separation and/or gas sequestration processes. The reactive metal nucleation substrate may include reactive metals from Group II, Group I, or Group XIII of the periodic table, for example, in alloyed form with other metals and/or nonmetal elements.

摘要： Manual and automated methods of pre-charging an empty or partially empty insulated container with CO2 snow are provided. A first location such as a charging location charges CO2 liquid into a container to create a pre-charged container with CO2 snow. The charging location prepares the pre-charged container for delivery to a second location, either by itself, or through a third party. The second location may be a clinical site, which upon receipt of the pre-charged container, loads a perishable item such as a biological sample into the pre-charged container. A user receives the pre-charged container with perishable item and removes the perishable item from the pre-charger container for testing (e.g., biological testing). Depending on the level of depletion of the CO2 snow in the pre-charged container, the user returns the depleted container to the first location or the intermediate location.

摘要： A method for automatically dispensing and vending carbon dioxide (CO2) snow block is disclosed. The automatic dispensing system contains multiple containers of different volumes. A user can input the volume of CO2 snow block into a controller, such as a programmable logic controller (PLC). The controller uses the inputted volume and process information to determine which container to utilize for the automated filling process. The controller can configure the selected container into a filling orientation into which liquid CO2 can flow to generate CO2 snow block. Upon detection of the completion of the fill, the container is configured into a dispensing orientation from which the CO2 snow block is released into an access region from which the user can retrieve the CO2 snow block. The control methodology may also be used to auto charge a single container located within a charging station as disclosed herein.

摘要： A method and device for forming slabs of dry ice is shown. A dry ice extruding machine has been modified with a die that has a slot for extruding a slab of dry ice therethrough. The slot is blocked until a puck is formed in an end of a forming chamber of the dry ice extruding machine. The block is then removed and dry ice extruded to a desired length and then broken to give a slab of dry ice. The last step is repeated over and over as the extruded portion reaches the desired length to give the number of slabs wanted.

摘要： A process and system for producing pellets of high density carbon dioxide or other gases utilize a chamber containing a plurality of cell-like freezing compartments within which ice is to be formed. A gas desired to be frozen into ice is introduced into the chamber while the internal pressure of the chamber is maintained at a level which is below the equilibrium triple pressure of the gas. The temperature of the freezing compartments is lowered to a temperature which is below the equilibrium vapor pressure temperature of the gas at the chamber pressure so that the gas condenses into ice within the compartments. The temperature of the freezing compartments is thereafter raised so that the ice is thereby released from and falls out of the compartments as pellets for collection.

摘要： A dry ice pelletizer includes a ram structure that eliminates the need for piston rings to form the pellets thereby eliminating contamination of the pellets from piston ring wear products and piston/cylinder lubricants. The ram structure is pulled down into compression contact with dry ice snow formed in a snow chamber by a pair of hydraulic actuators coupled to a cross-head. The physical separation of the ram and the actuators further eliminates the source of contamination from hydraulic actuator fluid.
