In one embodiment, a liquid ring compressor includes a shaft, a main body inner casing disposed about the shaft to form a chamber between the shaft and the main body inner casing, and an inlet configured to remove a portion of liquid from a wet gas and to direct the wet gas into the chamber. The liquid ring compressor also includes an impeller rotatably disposed within the chamber and configured to direct a remaining portion of the liquid in the wet gas out towards the main body inner casing to form a liquid ring within the chamber to compress the wet gas.

    摘要： A method for separating carbon dioxide (CO2) from a gas stream is provided. The method includes cooling the gas stream in a cooling stage to form a cooled gas stream and cooling the cooled gas stream in a converging-diverging nozzle to form one or both of solid CO2 and liquid CO2. The method further includes separating at least a portion of one or both of solid CO2 and liquid CO2 from the cooled gas stream in the converging-diverging nozzle to form a CO2-rich stream and a CO2-lean gas stream. The method further includes expanding the CO2-lean gas stream in an expander downstream of the converging-diverging nozzle to form a cooled CO2-lean gas stream and circulating at least a portion of the cooled CO2-lean gas stream to the cooling stage for cooling the gas stream. Systems for separating carbon dioxide (CO2) from a CO2 stream are also provided.

    摘要： System and method for automatically determining a final set of tuning/calibration parameters for designing a new turbo-machinery. The method includes inputing an initial set of tuning/calibration parameters; calculating family turbo-machinery quantities based on the initial set of tuning/calibration parameters; comparing the calculated family turbo-machinery quantities with measured quantities and calculating a first error between the calculated family quantities and the measured quantities; calculating a second error between the initial set of tuning/calibration parameters and default values of the turbo-machine variables; forming a modified objective function that includes both the first and second errors; during an iterative process, varying the initial set of tuning/calibration parameters in such a way that the final set of tuning/calibration parameters is found; and storing in a database the final set of tuning/calibration parameters for the family.

    摘要： A waste heat recovery system includes a heat recovery cycle system coupled to at least two separate heat sources having different temperatures. The heat recovery cycle system is coupled to a first heat source and at least one second heat source. The heat recovery cycle system is configured to circulate a working fluid. The at least one second heat source includes a lower temperature heat source than the first heat source. The working fluid is circulatable in heat exchange relationship through a first heat exchange unit, a second heat exchange unit for heating the working fluid in the heat recovery cycle system. The first heat exchange unit is coupled to the at least one second heat source to heat at least a portion of a cooled stream of working fluid to a substantially higher temperature.
