  • Patent number: 9958200
    Abstract: A method is provided for separating off acid gases, in particular CO2 and H2S, from a hydrocarbon-rich fraction, in particular natural gas. The hydrocarbon-rich fraction is cooled and partially condensed. The resultant CO2-enriched liquid fraction is separated by rectification into a CO2-rich liquid fraction and a CO2-depleted gas fraction. The hydrocarbon-rich fraction is cooled close to the temperature of the CO2 triple point by means of a closed multistage refrigeration circuit. The refrigerant is a CO2 fraction of greater than 99.5% by volume. The rectification column is operated at a pressure between 40 and 65 bar. The reboiler of the rectification column is heated by means of a condensing refrigerant substream of the refrigeration circuit that is at a suitable pressure level.

  • Publication number: 20180045459
    Abstract: A process for liquefying a hydrocarbon-rich fraction, in particular natural gas, where the hydrocarbon-rich fraction is precooled and subjected to water separation and a subsequent drying process before liquefaction and the hydrocarbon-rich fraction is liquefied against at least one mixed refrigerant circuit, where the refrigerant circulating in the mixed refrigerant circuit is compressed in at least two stages, subsequently at least partially condensed and the liquid fraction formed here is at least partly mixed into the refrigerant which has been compressed to an intermediate pressure is described. A substream of the liquid fraction serves for precooling the hydrocarbon-rich fraction to be liquefied before it is fed to the water separation, where heat exchange between the liquid fraction and the hydrocarbon-rich fraction to be liquefied is effected by means of at least one heat exchanger system.

  • Patent number: 9841229
    Abstract: A process for cooling a hydrocarbon-rich fraction, in particular natural gas, against a refrigerant circuit. In this process, the compressed refrigerant is divided into three refrigerant substreams. Whereas the first substream is work-producingly expanded in a warm expander and the second substream is work-producingly expanded in a cold expander, the third substream is work-producingly expanded at the lowest temperature level. The result therefrom is that the operating point of the cold expander is shifted in such a manner that the refrigeration output of the two expanders is situated in a ratio between 40/60 and 60/40.

  • Publication number: 20170336138
    Abstract: The invention relates to an integrated process and apparatus for liquefaction of natural gas and recovery of natural gas liquids. In particular, the improved process and apparatus reduces the energy consumption of a Liquefied Natural Gas (LNG) unit by using a portion of the already cooled overhead vapor from a fractionation column from an NGL (natural gas liquefaction) unit to, depending upon composition, provide, for example, reflux for fractionation in the NGL unit and/or a cold feed for the LNG unit, or by cooling, within the NGL unit, a residue gas originating from a fractionation column of the NGL unit and using the resultant cooled residue gas to, depending upon composition, provide, for example, reflux/feed for fractionation in the NGL and/or a cold feed for the LNG unit, thereby reducing the energy consumption of the LNG unit and rendering the process more energy-efficient.

  • Patent number: 9752825
    Abstract: A process for liquefying and subcooling a hydrocarbon-rich fraction, particularly natural gas, is described wherein, once cooled down, the fraction is subjected to a partial condensation to remove heavy hydrocarbons, particularly benzene, by the steps of: a) the liquefied hydrocarbon-rich fraction is subcooled in a separate heat exchanger (normal mode), b) the supply of the liquefied hydrocarbon-rich fraction to the heat exchanger is interrupted at the latest when a defined solid deposition value in the heat exchanger is reached (cleaning mode), c) the solid in the heat exchanger is melted with a defrost gas and drawn off from the heat exchanger and d) the liquefied hydrocarbon-rich fraction is subsequently returned to the heat exchanger.
