Patent ID: 7462506

Claim:
A method for removing carbon dioxide from a cavity in a chip module assembly, comprising the steps of: providing a chip module assembly enclosing at least one chip within a cavity; providing a carbon dioxide getter comprising a liquid composition including 1.8-diaza-bicyclo-[5.4.0]-undec-7-ene in a solvent that includes 1-hexanol; mounting the carbon dioxide getter relative to the chip module assembly so that the carbon dioxide getter is exposed, directly or indirectly, to the cavity through a gas-permeable membrane; providing a regeneration tank, wherein the regeneration tank is in fluid communication with the carbon dioxide getter via one or more flowlines; transferring an ionic liquid reaction product generated within the carbon dioxide getter to the regeneration tank via at least one of the one or more flowlines; reacting, in the regeneration tank, the ionic liquid reaction product and an inert gas to regenerate the getter liquid composition; returning the regenerated getter liquid composition from the regeneration tank to the carbon dioxide getter via at least one of the one or more flowlines.
