  • Publication number: 20250052457
    Abstract: A heat pump method, in which a working medium is vaporized at a lower temperature level using a heat source and subsequently compressed and liquefied at an upper temperature level using a heat sink, wherein: after being vaporized and before being compressed, the working medium is superheated; a temperature increase caused by the compression is restricted by means of injection into the compression; and after being compressed and before being liquefied, the working medium is saturated at the upper temperature level. The present invention also relates to a corresponding heat pump arrangement.

  • Publication number: 20240239728
    Abstract: A method for producing ethylene and/or other olefins by steam cracking includes charging one or more crackers with a paraffin-containing feed and withdrawing a crude gas from the one or more crackers. The crude gas is subjected at least in part to a treatment comprising a crude gas compression and a thermal separation using a C2 refrigerant and a C3 refrigerant. A crude gas compressor is used for the crude gas compression, wherein the ethylene refrigerant is compressed using a C2 refrigerant compressor. The propylene refrigerant is compressed using a C3 refrigerant compressor. The crude gas compressor comprises two serial compressor trains. The compressor trains, the C2 refrigerant compressor and the C3 refrigerant compressor are each operated at least in part using electrical drives, which have at least partially identical performance features, are provided as structurally identical variable-speed drives, and are each fed via frequency converters.

  • Publication number: 20220170695
    Abstract: The invention relates to a method for condensing a gas, wherein the gas is subjected to cooling in indirect heat exchange with a refrigerant and at least part of the refrigerant is subjected, after the heat exchange with the gas, to compression by means of a drive (GT1) that produces waste heat and to a partial or complete condensing process. After the partial or complete condensing process, a first portion of the refrigerant is subjected to the heat exchange with the gas and a second portion of the refrigerant is subjected, in succession, to pressurization, heating by means of the waste heat of the drive (GT1) and work-performing expansion and thereafter is fed back to the partial or complete condensing process. The invention further relates to a corresponding system.

  • Patent number: 10457617
    Abstract: A method for obtaining an ethylene product in a supercritical state is proposed, in which method a gas mixture containing predominantly or exclusively ethylene and ethane is separated in a distillation column (1), which is operated at a distillation pressure level of from 5 to 15 bar, into an overhead product containing predominantly or exclusively ethylene and a bottom product containing predominantly or exclusively ethane, the overhead product being withdrawn in the gaseous state from the head of the distillation column (1) and a first portion thereof being liquefied and returned as reflux to the distillation column (1) and a second portion thereof being converted into a supercritical state and being used as the ethylene product.

  • Publication number: 20190145703
    Abstract: A method is proposed for compressing a gas in stages in a compressor arrangement (100, 200, 300, 400) having a plurality of compression stages (I-VI) which are connected together sequentially by a main line (1) and in which the gas, guided through the main line (1), is respectively compressed from a suction-side pressure level to a pressure-side pressure level and is heated by this compression from a suction-side temperature level to a pressure-side temperature level, wherein a feedback amount of the gas, guided through the main line (1), is at least temporarily removed from the main line (1) downstream of one of the compression stages (V), is fed to an expansion process, and is fed back into the main line (1) upstream of the same compression stage (V).

  • Publication number: 20150253068
    Abstract: A method is described for cooling a hydrocarbon-rich fraction, in particular of natural gas, wherein the hydrocarbon-rich fraction (1) is cooled against at least one coolant circuit (10-15), the coolant has at least nitrogen, carbon dioxide, methane and/or C2+ hydrocarbons, the coolant is compressed by means of at least one turbocompressor (C1) having one or more gas-lubricated sliding-ring seals, and as primary seal gas, a substream of the coolant and/or an external gas or gas mixture having substantially nitrogen and/or methane is fed to the turbocompressor (C1), and as secondary seal gas, nitrogen is fed. According to the invention, at least one nitrogen-rich stream (21) is withdrawn at least at times from the coolant circuit (10-15).
