  • Publication number: 20240101430
    Abstract: An apparatus for the separation of a flow containing carbon dioxide by distillation comprising a heat exchange means, a distillation column, means for sending the flow to be cooled in the heat exchange means down to a first intermediate temperature in order to form a liquid flow at a first temperature and at a first pressure, means for dividing the liquid flow in order to form a first fraction and a second fraction, means for expanding the first fraction to the pressure of a distillation column, means for sending the expanded first fraction to an intermediate level of the distillation column, means for exiting the second fraction from the cold end of the heat exchange means after cooling, means for expanding the cooled second fraction to the pressure of the distillation column, means for sending the second fraction to the distillation column and means for the withdrawal, from the bottom of the column, of a liquid flow.

  • Publication number: 20240068744
    Abstract: In a method for liquefying a gas rich in carbon dioxide, the gas is compressed to a first pressure greater than its critical pressure in a compressor to form a compressed gas, the compressed gas is cooled through heat exchange with a refrigerant to a variable temperature to form a cooled compressed gas with a density between 370 and 900 kg/m3, the cooled compressed gas is cooled at supercritical pressure in a first heat exchanger to a temperature below the critical temperature, the gas cooled below the critical temperature is expanded to a second pressure between 45 and 60 bara to form a diphasic fluid which is separated in a phase separator to form a liquid and a gas, and a liquid portion originating from the phase separator provides cold to the first heat exchanger.

  • Publication number: 20220152324
    Abstract: A nasal delivery device for delivering substance to a nasal cavity of a subject comprises: a housing (15); a nosepiece (17) for fitting to a nasal cavity of the subject: a mouthpiece (19) through which the subject in use exhales; and a flexible coupling (20) which couples the mouthpiece to the housing, wherein the flexible coupling provides for asymmetric translation of the mouthpiece relative to the nosepiece.

  • Publication number: 20210290867
    Abstract: A nasal delivery device for and method of delivering substance to a nasal airway of a subject, the delivery device comprising: a nosepiece (117) for fitting to a nasal cavity of a subject, a mouthpiece (119) into which the subject in use exhales; a delivery unit, which comprises an actuation part which is manually displaceable to actuate the delivery unit to deliver substance from the nosepiece; and a valve assembly (127) which is fluidly connected to the nosepiece and the mouthpiece, wherein the valve assembly comprises a body element (128) and a valve element (131) which is movably disposed to the body element between closed and open configurations by manual displacement of the actuation part of the delivery unit to provide for an air flow through the nosepiece simultaneously with delivery of substance.
