Definitions

  • the present invention is directed to a multi-refrigerant cooling system as well as to a method for adjusting the composition of a refrigerant mixture of a multi-refrigerant cooling system.
  • Multi-refrigerant cooling systems are previously known and operate with a refrigerant mixture of two or more refrigerants having different condensation temperatures. Thus, a mixture of refrigerants is circulated in the cooling circuit of the multi-refrigerant cooling system. Multi-refrigerant cooling systems are used, in particular, in industrial applications demanding very low temperatures. A typical application is the capture of carbon dioxide (CO 2 ) from exhaust gases by frosting of CO 2 ice.
  • CO 2 carbon dioxide
  • Multi-refrigerant cooling systems are disclosed in for example U.S. Pat. No. 7,073,348 and US 2006/0277942.
  • the disclosed systems operate according to a cooling principle called integrated cascade.
  • a multi-refrigerant cooling system is shut off, emptied of its refrigerant mixture and refilled with a refrigerant mixture of desired composition.
  • Objects of the present invention include the provision of a possibility for re-use of refrigerants when an adjustment of the composition of a refrigerant mixture of a multi-refrigerant cooling system is performed; the provision of a possibility of keeping the amount of refrigerants that is wasted during an adjustment of the composition of a refrigerant mixture of a multi-refrigerant cooling system to a minimum; and the provision of a possibility to carry out an adjustment of the composition of the refrigerant mixture during maintained operation of a multi-refrigerant cooling system.
  • a multi-refrigerant cooling system comprising a cooling circuit for circulation of a refrigerant mixture comprising two or more refrigerants, the cooling circuit comprising a compressor having an inlet and an outlet; one or more separator(s) configured to separate and withdraw a respective refrigerant fraction of the refrigerant mixture; and a client, the outlet of the compressor being connected to the client via the separator(s), wherein each separator is connected to a respective holding tank via a respective withdrawal conduit, each holding tank being arranged to receive said respective refrigerant fraction from its respective separator, wherein each holding tank further is connected to the cooling circuit via a supply conduit, the supply conduit being configured to supply one or more refrigerant fraction(s) to the cooling circuit.
  • a multi-refrigerant cooling system allowing adjustment of the composition of its refrigerant mixture to be performed under favourable conditions.
  • adjustment in view of changing client temperature requirements and or changing environmental temperature can be addressed by changing the composition of the refrigerant blend during operation of the cooling system.
  • the term “client” relates to an item, along the cooling circuit, which is to be cooled by the multi-refrigerant cooling system. Apart from what is described herein, the detailed layout of the cooling circuit, or its working principle, is not critical to the present invention.
  • the system may comprise a further holding tank connected via a further withdrawal conduit to the cooling circuit at a position between the separator(s) and the client, the further holding tank being arranged to receive a refrigerant fraction from the cooling circuit, wherein the further holding tank further is connected to the cooling circuit via the supply conduit.
  • a refrigerant fraction remaining in the cooling circuit after separation, and subsequent withdrawal to holding tank(s), of one or more other refrigerant fraction(s) by the separator(s) may be utilized when adjusting the composition of the refrigerant mixture.
  • the supply conduit may be connected to the cooling circuit at a position between the client and the inlet of the compressor.
  • a refrigerant fraction is typically maintained in its holding tank at the pressure of its respective separator or slightly below. Since the separator(s) typically belong to the high pressure side of the cooling circuit, it is beneficial to supply such a refrigerant fraction from its holding tank via the supply conduit to the cooling circuit at a position between the client and the inlet of the compressor, i.e. on the low pressure side of the cooling circuit. Thus, it is possible to supply to the cooling circuit such a refrigerant fraction without, or with less need for, pumps or other pressure regulating means. Therefore, the system may be provided with holding tank(s) that is/are maintained at a pressure between the pressure in the cooling circuit where the respective refrigerant fraction is separated and the pressure in the cooling circuit where the supply conduit is connected.
  • Each withdrawal conduit may further be connected to a flare. If a withdrawn fraction is not of desirable purity, this fraction may be removed from the cooling circuit, rather than stored and/or reused. Therefore, a separated and withdrawn refrigerant fraction of the refrigerant mixture may be discarded. This may conveniently be achieved by passing of the separated and withdrawn refrigerant fraction to an outlet flare.
  • the client may be a carbon dioxide frosting vessel, i.e. a vessel in which gaseous carbon dioxide is captured as carbon dioxide ice at low temperature.
  • the present invention additionally relates to the use of a multi-refrigerant cooling system as described above for cooling of a carbon dioxide frosting vessel.
  • the system may be configured to be controlled by a control system.
  • a control device with associated control signalling infrastructure keep track of the quantities in each holding tank via, for example pressure sensors, and the control device may further keep track of the percentages of each refrigerant in the system via a multi-component detector.
  • the control device may also determine the rate and length of opening of different control valves, according to what adjustment to the refrigerant mixture is needed.
  • certain objects of the present invention are accomplished by a method for adjusting the composition of a refrigerant mixture of a multi-refrigerant cooling system, said method comprising the following steps:
  • composition of the refrigerant mixture of the multi-refrigerant cooling system is adjusted to a new composition, said new composition being different from the composition of the refrigerant stream;
  • one or more, preferably all, of the fraction(s) withdrawn in step a) may be individually stored. Storing the withdrawn fractions individually facilitates further treatment, such as recovery or recycling, thereof. Any fraction not stored may be discarded, e.g., flared off. A withdrawn fraction may typically be discarded, rather than stored, if this fraction is not of desirable purity.
  • the refrigerant stream supplied in step b) may comprise, preferably consist of, one or more of the stored fraction(s). Fraction(s) withdrawn from the multi-refrigerant cooling system may thus be returned thereto, albeit in amounts and/or proportions rendering the composition of the refrigerant mixture of the multi-refrigerant cooling system to change. Make-up refrigerants, not withdrawn from the multi-refrigerant cooling system but typically supplied substantially pure or in mixtures of a set composition, may conveniently be supplied to the multi-refrigerant cooling system as part of the refrigerant stream of step b).
  • the number of fractions withdrawn in step a) may be equal to or less than, preferably equal to, the number of refrigerants in the refrigerant mixture of the multi-refrigerant cooling system.
  • any withdrawn fraction of the refrigerant mixture i.e., the fraction(s) withdrawn in step a) may be discarded. As mentioned above, such fraction(s) may be flared off. In such a situation, the number of fractions withdrawn in step a) may suitably be one.
  • Make-up refrigerants not withdrawn from the multi-refrigerant cooling system but typically supplied substantially pure or in mixtures of a set composition, may however be supplied to the multi-refrigerant cooling system as part of the refrigerant stream of step b).
  • the stored fraction(s) may each be maintained at a pressure between the pressure of the refrigerant mixture at the position of the multi-refrigerant cooling system where in step a) the respective fraction is withdrawn and the pressure of the refrigerant mixture at the position of the multi-refrigerant cooling where step b) is performed.
  • the fraction(s) withdrawn in step a) may each be withdrawn at a position of the multi-refrigerant cooling system where the refrigerant mixture is present at a higher pressure than at the position of the multi-refrigerant cooling system where step b) is performed.
  • the multi-refrigerant cooling system may cool a carbon dioxide frosting vessel, i.e. a vessel in which gaseous carbon dioxide is captured as carbon dioxide ice at low temperature.
