Definitions

  • the present invention relates to a method for separating a gas rich in carbon dioxide by partial condensation and permeation.
  • a gas rich in carbon dioxide contains at least 65 mol %, or at least 80 mol % or even at least 90 mol % of carbon dioxide, on a dry basis.
  • the gas rich in carbon dioxide contains at least one lighter gas, such as oxygen, nitrogen, carbon monoxide, hydrogen.
  • it contains less than 5 mol % of methane, or even less than 2 mol % of methane.
  • the low temperature separation of a gas rich in carbon dioxide is particularly chosen as a means of capturing CO 2 when the concentration of the gas is high enough ( ⁇ 30 mol %).
  • the gas Before being cooled (usually as close as possible to the triple point of CO 2 ), generally the gas must be dried and its pressure must be increased for the purpose of capturing the CO 2 at the desired yield, since the separation is essentially based on partial condensation.
  • Membranes will be chosen in which the CO 2 will permeate preferably with respect to the other compounds in order to capture the CO 2 in the permeate from the membranes.
  • Membranes capable of carrying out such a separation are known from WO-A-2011/084516 and from “CO 2 Capture by Subambient Membrane Operation” by Kulkarni et al., 2010 NETL CO 2 Capture Technology.
  • the membrane thus acts as a heat exchanger, to the extent that in certain configurations (such as counter flow) the temperature drop is greater for the residue than for the permeate.
  • the present invention relates to the adaptation of the outlet temperature of the membranes in order to prevent excessively low temperatures involving risks of solidification of the CO 2 during the recycling of the cold from the fluids at the outlet of the membranes.
  • the invention therefore consists in limiting the temperature drop to a temperature above the triple point of the CO 2 in order to be able to ensure the recycling of the cold generated by the membrane separation in the remainder of the process.
  • the LP CO 2 is subcooled, before the expansion thereof, against all the gases whose temperature is significantly lower than that of the exchange line (that of the higher temperatures). This makes it possible, in this way, to recycle the low-temperature cold against hotter fluids at similar temperatures which optimizes the system by minimizing exergetic losses during heat exchanges;
  • a process for separating a gas rich in carbon dioxide by partial condensation and permeation, wherein the gas rich in carbon dioxide is cooled at least in a first heat exchanger, the gas rich in carbon dioxide cooled in the first heat exchanger or a fluid derived from this gas goes into a first phase separator at a first temperature between ⁇ 50° C. and ⁇ 53° C., a liquid enriched in carbon dioxide is withdrawn from the first phase separator and serves as product or is treated in order to enrich it even more in carbon dioxide, a gas depleted in carbon dioxide from the first phase separator is warmed in the first exchanger or a second exchanger to a second temperature between ⁇ 35° C.
  • the warmed gas undergoes at least one permeation step in the permeation unit in order to produce at least two fluids that are then warmed in the exchanger in which the depleted gas was warmed, the fluid resulting from the permeation unit, warmed in the exchanger, which leaves the permeation unit at the lowest temperature being at a temperature above ⁇ 54° C.
  • an apparatus for separating a gas rich in carbon dioxide by partial condensation and permeation, comprising a first heat exchanger, means for sending the gas rich in carbon dioxide to be cooled at least in a first heat exchanger, a first phase separator, means for sending the gas rich in carbon dioxide cooled in the first heat exchanger or a fluid derived from this gas to the first phase separator at a first temperature between ⁇ 50° C.
