摘要： Systems and methods of CO2 desublimation are presented in which refrigeration content is retained within the system. Most preferably, refrigeration content is recycled by providing the refrigeration content of a CO2-lean feed gas to the CO2-containing feed gas and to pre-cooling of a desublimator, and/or by providing refrigeration of effluent of a desublimator in regeneration to a refrigerant in a closed refrigeration cycle for deep-cooling of another desublimator.

摘要： Acid gas is removed from a high pressure feed gas that contains significant quantities of CO2 and H2S. In especially preferred configurations and methods, feed gas is contacted in an absorber with a lean and an ultra-lean solvent that are formed by flashing rich solvent and stripping a portion of the lean solvent, respectively. Most preferably, the flash vapors and the stripping overhead vapors are recycled to the feed gas/absorber, and the treated feed gas has a CO2 concentration of less than 2 mol % and a H2S concentration of less than 10 ppmv, and more typically less than 4 ppm.

摘要： A LNG liquefaction plant includes a propane recovery unit including an inlet for a feed gas, a first outlet for a LPG, and a second outlet for an ethane-rich feed gas, an ethane recovery unit including an inlet coupled to the second outlet for the ethane-rich feed gas, a first outlet for an ethane liquid, and a second outlet for a methane-rich feed gas, and a LNG liquefaction unit including an inlet coupled to the second outlet for the methane-rich feed gas, a refrigerant to cool the methane-rich feed gas, and an outlet for a LNG. The LNG plant may also include a stripper, an absorber, and a separator configured to separate the feed gas into a stripper liquid and an absorber vapor. The stripper liquid can be converted to an overhead stream used as a reflux stream to the absorber.

摘要： Gas processing plants and methods are contemplated in CO2 is effectively removed to very low levels from a feed gas to an NRU unit by adding a physical solvent unit that uses waste nitrogen produced by the NRU as stripping gas to produce an ultra-lean solvent, which is then used to treat the feed gas to the NRU unit. Most preferably, the physical solvent unit includes a flash unit and stripper column to produce the ultra-lean solvent.

摘要： A method comprises: transmitting, to a server, a request for performance metrics of a utility system; receiving, from the server, the performance metrics; creating a design for a power distribution system based on the performance metrics; obtaining components for the power distribution system based on the design; and installing the components to implement the design. A system comprises: a database server configured to: receive documents associated with components of a utility system, extract equipment rating information from the documents, and store the equipment rating information in a usable form in a database; and a model computer coupled to the database server and configured to: receive the equipment rating information from the database server, create a utility system model based on the equipment rating information, and determine short-circuit parameters for nodes associated with customers.

摘要： A LNG liquefaction plant system includes concurrent power production, wherein the refrigeration content of the refrigerant or SMR is used to liquefy and sub-cool a natural gas stream in a cold box or cryogenic exchanger. For concurrent power production, the system uses waste heat from refrigerant compression to vaporize and superheat a waste heat working fluid that in turn drives a compressor for refrigerant compression. The refrigerant may be an external SMR or an internal LNG refrigerant working fluid expanded and compressed by a twin compander arrangement.

摘要： A method of producing fuel from CO2 comprising introducing natural gas, steam, and recovered CO2 to a reformer to produce unshifted syngas characterized by a molar ratio of hydrogen to carbon monoxide of from about 1.7:1 to about 2.5:1; introducing the unshifted syngas to a water gas shift unit to produce a shifted syngas, wherein an amount of CO2 in the shifted syngas is greater than in the unshifted syngas; separating the CO2 from the shifted syngas to produce recycle CO2 and a hydrogen-enriched syngas; recycling the recycle CO2 to the reformer; introducing the unshifted syngas to a Fischer-Tropsch (FT) unit to produce an FT product, FT water, and FT tail gas, wherein the FT product comprises FT liquids and FT wax; and separating the FT liquids from the FT product to produce a fuel.

摘要： A duct assembly for flowing fluids includes a first duct positioned above the ground. The first duct is configured to flow a first fluid. In addition, the duct assembly includes a second duct positioned above the ground. The second duct is configured to flow a second fluid. The first duct and the second duct isolate the first fluid and the second fluid from each other. Further, the duct assembly includes a stand supporting the first duct and the second duct above the ground. The stand has an upper end positioned below the first duct and the second duct.
