Abstract
A liquid is degassed with an apparatus including a membrane contactor, where the liquid is drawn through the apparatus by gravity.
Claims18
An apparatus for degassing a liquid comprising:
- a shell-side liquid flow membrane contactor having a liquid inlet, a liquid outlet, and a vacuum port,
- a first tube having a proximal end and a distal end, said proximal end of said first tube being connected to said liquid inlet of said membrane contactor,
- a reservoir connector being connected to said distal end of said first tube, and
- a second tube having a proximal end and a distal end, said proximal end of said second tube being connected to said liquid outlet of said membrane contactor,
- wherein, during use, said distal end of said first tube being positioned above said membrane contactor and said distal end of said second tube being positioned below said membrane contactor, whereby liquid being drawn through said membrane contactor by gravity.
2 more elements
A method of degassing a liquid comprising the steps of:
- gravity-feeding a liquid containing an entrained gas to an apparatus for degassing the liquid, the apparatus having a shell-side liquid flow membrane contactor,
- degassing the liquid containing the entrained gas by operation of diffusion of the entrained gas across a membrane of the apparatus, and
- discharging a liquid having less entrained gas than the liquid containing the entrained gas from the apparatus.
