The present invention relates to an apparatus and method for manufacturing a dry ice nugget using liquid carbon dioxide and a dry ice nugget manufactured by the method, wherein the method includes injecting liquid carbon dioxide into a cylinder having a predetermined internal space formed therein, accumulating the liquid carbon dioxide, which is solidified in the internal space, at a lower end of the cylinder, pressurizing the predetermined internal space by lowering a piston located above the cylinder, and compression-molding the liquid carbon dioxide in a solid state pressurized by the piston.

The present disclosure relates to systems and methods that provide a low pressure liquid CO.sub.2 stream. In particular, the present disclosure provides systems and methods wherein a high pressure CO.sub.2 stream, such as a recycle CO.sub.2 stream from a power production process using predominately CO.sub.2 as a working fluid, can be divided such that a portion thereof can be expanded and used as a cooling stream in a heat exchanger to cool the remaining portion of the high pressure CO.sub.2 stream, which can then be expanded to form a low pressure CO.sub.2 stream, which may be in a mixed form with CO.sub.2 vapor. The systems and methods can be utilized to provide net CO.sub.2 from combustion in a liquid form that is easily transportable.

The disclosure provides a system to capture greenhouse gas, such as carbon dioxide, from exhausts of greenhouse gas emission sources on industrial sites, such as industrial grade power generators, and liquefy it for temporary onsite storage for collection and transportation to specifics sites for permanent carbon dioxide sequestration or utilization. The system can integrate the greenhouse gas emission source, with exhaust gas collection equipment, greenhouse gas capture equipment, greenhouse gas liquification equipment, and greenhouse gas fluid storage equipment for the onsite collection of the captured greenhouse gas from the greenhouse gas emission sources. The system can further include an on demand transport collection system having one or more transporters that can remove the liquified greenhouse products from the onsite storage equipment and transport the greenhouse products to a location for environmentally acceptable sequestration or utilization, thus reducing the amount of greenhouse gas released to the atmosphere.

A marine vessel and method for carbon capture and sequestration are described. The marine vessel includes a buoyant hull, a cryogenic storage tank within the hull, and a gaseous carbon dioxide loading manifold. The marine vessel also includes a carbon dioxide liquefaction system in fluid communication with the cryogenic storage tank downstream of the carbon dioxide liquefaction system and with the gaseous carbon dioxide loading manifold upstream of the carbon dioxide liquefaction system. Finally, the marine vessel includes a carbon dioxide supercritical system in fluid communication with the cryogenic storage tank. In operation, the marine vessel moves between multiple locations, where gaseous carbon dioxide is onboarded, liquified and stored. Thereafter, the marine vessel transports the liquified carbon dioxide to a location adjacent an offshore geological reservoir. The liquefied carbon dioxide is then pressurized to produce supercritical carbon dioxide, which is then injected directly into the reservoir from the marine vessel.

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.

The invention relates to: a method for monitoring a process engineering installation, in which a model of the process engineering installation is used to ascertain values of at least one performance parameter of the process engineering installation from actual values of at least one operating parameter of the process engineering installation that occur during operation of the process engineering installation, wherein the model is used to ascertain comparison values of the at least one performance parameter of the process engineering installation from setpoint values of the at least one operating parameter, and wherein mutually corresponding values and comparison values of the at least one performance parameter are taken as a basis for ascertaining at least one performance gap in the operation of the process engineering installation and to a process engineering installation.

Integration of a natural gas liquefaction system, a hydrogen production system, and power generation system to increase CO2 capture and improve overall plant efficiency. The predominantly methane endflash is sent to the hydrogen production system which produces hydrogen and CO2. The CO2 may be captured or beneficially used. At least a portion of the hydrogen produced is used to fuel gas turbines in the power generation which, in turn, provides power for the refrigeration compressor of the natural gas liquefaction system—either in the form of mechanical work or electricity.

A system and method for power generation and CO.sub.2 sequestration include a fuel cell system configured to generate power using natural gas (NG), a container configured to store liquid natural gas (LNG), and a fluid processor configured to convert LNG received from the container into NG and to convert exhaust output from the fuel cell system to dry ice by transferring heat between and the LNG and the exhaust.

A method for operating the liquid air energy storage (LAES) includes production of the storable liquid air through consumption of a low-demand power and recovery the liquid air for co-production of an on-demand power and a high-grade saleable cold thermal energy which may be used, say, for liquefaction of the delivered natural gas; in so doing zero carbon footprint is provided both for fueled augmentation of the LAES power output and for LNG co-production at the LAES facility.

A system captures carbon dioxide from a flue gas of a power generation facility by using cold heat of liquefied natural gas and utilizes the captured carbon dioxide for mining natural gas, using heat of the flue gas to regasify the LNG. Solidified dry ice is captured from gaseous carbon dioxide contained in the flue gas, and the captured dry ice is used as filler when mining natural gas. The system includes a mining facility, a vehicle to transport LNG liquefied by the mining facility; and a facility for regasifying the transported LNG and capturing dry ice from the carbon dioxide. In the regasification and capture facility, the flue gas exchanges heat with the LNG, thereby regasifying the LNG at an increased temperature and capturing the dry ice from the carbon dioxide. The captured dry ice is transported to the mining facility, which uses it for mining the natural gas.
