Patent

CA 2203051

The present invention is directed to a microporous membrane contactor for degassing liquids at temperatures greater than (>) 60°C and at pressures greater than or equal (~) to 40 psig. The contactor has a microporous hollow fiber membrane adapted to withstand collapse and resist appreciable pore shrinkage or pore closure when subjected to liquid temperatures greater than (>) 60°C and liquid pressures greater than or equal to (~) 40 psig for a period of greater than or equal to (~) 30 days. A housing encloses the membrane.

La présente invention a trait à un contacteur à membrane microporeuse pour dégazer les liquides à des températures supérieures à (>) 60 degrés Celsius et à des pressions supérieures ou égales à (~) 40 psig. Le contacteur comporte une membrane microporeuse de fibre creuse capable de résister à l'affaissement et à un rétrécissement appréciable des pores ou au blocage des pores lorsque les températures des liquides dépassent (>) 60 degrés Celsius et que les pressions des liquides sont supérieures ou égales à (~) 40 psig pour une période supérieure ou égale à (~) 30 jours. Une enveloppe entoure la membrane.
