摘要： The present application includes a plant for treating gas, particularly natural gas, supplied by a transmission network. The plant includes a gas inlet connected to the transmission network, a portion of the plant that decompresses, to a predefined outlet pressure, a first fraction of the gas from the inlet, and supplies the decompressed gas at a first outlet. The plant also includes another portion that liquifies a second fraction of the gas from the inlet and supplies the liquefied gas at a second outlet. The portion that carries out the decompressing includes a valve for throttling the first gas fraction, a heat exchanger establishing a thermal exchange relationship between the decompressing portion placed downstream the throttle valve and the portion that liquifies and supplies the gas, another heat exchanger establishing a thermal exchange relationship between the plant portions placed downstream the first heat exchanger and upstream the throttle valve. The portion that liquifies and supplies also includes a valve for throttling the second gas fraction that is downstream the first heat exchanger.

摘要： A method for the use of a gaseous effluent containing a CO2 gas fraction and a non-CO2 gas fraction, including at a first location: providing liquid nitrogen at a temperature less than −196° C., and causing the gaseous effluent to contact the liquid nitrogen to as to capture at least part of the CO2 present in the CO2 gas fraction as a mixture of CO2 particles and liquid nitrogen. Conveying at least part of the mixture to a second location, and at the second location, bringing the mixture into contact with one or more ingredients of a wet concrete before and/or during and/or after the wet concrete is prepared by blending the ingredients of the wet concrete in a blender, so that the mixture extracts heat from said one or more ingredients of the wet concrete, and CO2 from the mixture partially carbonates Ca-compounds present in the wet concrete.

摘要： Methods and systems for removing contaminants, such as water and/or carbon dioxide, from a gas stream, such as a natural gas stream or a flue gas stream. One or more solid-tolerant heat exchangers are employed to chill the gas stream to a temperature at which the contaminants solidify. The solidified contaminants may then be separated and removed from the gas stream. In one or more aspects, the one or more solid-tolerant heat exchangers may include a scraped heat exchanger.

摘要： A method and apparatus for producing liquefied natural gas. A pretreated natural gas stream is compressed in at least two serially arranged compressors to a pressure of at least 1,500 psia and cooled. The resultant cooled compressed natural gas stream is expanded in at least one work producing natural gas expander to a pressure less than 2,000 psia and no greater than the pressure to which natural gas stream has been compressed, thereby forming a chilled natural gas stream that is separated into a refrigerant stream and a non-refrigerant stream. The refrigerant stream is warmed in a heat exchanger through heat exchange with one or more process streams associated with pretreating the natural gas stream, thereby generating a warmed refrigerant stream. The warmed refrigerant stream and the non-refrigerant stream are then liquefied.
