  • the warming uses at least one heat exchanger to exchange heat with a process stream, for example the mixture of step (a).
  • the method may further include the step of warming and/expanding the second component fraction before the scrubbing step.
  • the flows of the cold separated first and second components are configured so as to flow though one or more multi-channel diffusion bonded and/or micro channel heat exchangers designed to cool the already cooled gas mixture to the operating temperature of the fractionation unit.
  • multi-channel diffusion bonded and/or micro channel heat exchangers are described for example in EP 0212878 and WO 2004/017008 the contents of which are incorporated by reference herein.
  • the mixture is further cooled to create a two phase gas/liquid mixture. The exact temperature and pressure required to achieve this will depend on exactly how selective this fractionation unit is required to be but in all cases it is critical that the mixture is prevented from becoming supercritical on the one hand or that the first component(s) freeze out on the other.
  • first component recovered in stage (b) will depend to a certain extent on its exact nature. If it is liquid carbon dioxide it may for example be piped or tankered offsite for underground storage. In this case it is desirable to liquefy any further gaseous first component recovered in step (c) and combine it with the material recovered in step (b). If on the other hand the liquid first component is carbonyl sulphide or hydrogen sulphide it may be more beneficial to restore it to the gaseous state so that the sulphur it contains can be recovered as elemental sulphur for example by feeding the first component to a Claus plant. In this case any gaseous first component recovered in step (c) can either be fed directly to such a plant or combined with that recovered in step (b) after it has been warmed and decompressed in a manner analogous to step (d).
  • the first component for example liquid carbon dioxide
  • the phase separation apparatus may recycle the first component.
  • carbon dioxide liberated from the solvent, for example methanol, of the solvent system is recycled to the front end of the phase separation unit and then joins the fresh feed from the hydrogen sulphide removal process (where present).
  • the result would be an increase in the flow rate of the carbon dioxide capture stream in the phase separation apparatus. If for example the solvent system is designed to remove
  • Figure 2 shows the features of a second example of a process including upstream sulphur removal
  • the liquid stream may be flashed through a valve (not shown in Figure 1) before going through LNG- 100, to give a higher cooling effect.
  • This stream is warmed yet again to -30 C in LNG- 100 before being expanded one last time in turbo expander EX4 to a pressure of 31 bar and a temperature of -5O 0 C. Finally the gas stream is passed through LNG-100 one more time and optionally a series of other heat exchangers (not shown) where it is warmed to a final temperature of 25 C The warm hydrogen-rich gas stream then leaves the plant via line 122'.
  • phase separation process By integrating the phase separation process, expander apparatus and solvent system, an arrangement in which all of the carbon dioxide capture occurs within the phase separation process can be achieved.

Abstract

L'invention porte sur un procédé pour séparer un mélange de gaz en un premier composant relativement condensable et un second composant relativement incondensable. Le premier composant comprend un ou plusieurs gaz choisis dans le groupe constitué par le dioxyde de carbone, le sulfure de carbonyle et le sulfure d'hydrogène et le second composant comprend un ou plusieurs gaz choisis dans le groupe composé de l'hydrogène, du méthane, de l'éthane, du monoxyde de carbone, de l'azote, de l'oxygène et des gaz de synthèse. Le processus lui-même comprend les étapes suivantes : (a) compression et refroidissement d'un mélange desdits premier et second composants dans au moins un compresseur et au moins un échangeur de chaleur jusqu'à une température et une pression élevée auxquelles les premiers composants se condensent, et un mélange gaz-liquide en deux phases est formé ; (b) division du mélange en deux phases ainsi formé en une première fraction composante liquide et une seconde fraction composante gazeuse séparées dans une unité de fractionnement ; (c) extraction du premier composant résiduel de la seconde fraction composante gazeuse séparée par lavage du second composant à une pression élevée avec un solvant (par exemple du méthanol) dans un laveur. Dans des exemples, le procédé comprend aussi une ou plusieurs étapes consistant à chauffer et à détendre la deuxième fraction composante gazeuse en utilisant au moins un échangeur de chaleur pour échanger de la chaleur avec un courant de traitement et au moins un turbodétendeur capable de récupérer l'énergie mécanique. Le procédé décrit a un rendement élevé en énergie et il est spécialement utilisable dans les installations électriques à hydrogène, des cycles intégrés combinés de gazéification (IGCC) et pour adoucir le gaz naturel acide.
