Spinning impingement multiphase contacting device

A method for deoxygenating water, comprising:

• introducing the water into the interior region of a rotatable permeable element, the rotatable permeable element, as a whole, having a porosity of less than about 40 pores per inch the rotatable permeable element defining an inner wall and an interior region, the rotatable permeable element rotating at a speed such that the tangential velocity at its inner wall is at least about 18 meters per second;
• and
• contacting the water inside the rotatable permeable element with steam, thereby causing transfer of oxygen from the water to the steam.

A process for deoxygenating water comprising:

• rotating a rotatable permeable element disposed within a chamber, the rotatable permeable element, as a whole, having a porosity of less than about 40 pores per inch, the rotatable permeable element defining an inner wall and an interior region, the rotatable permeable element rotating at a speed such that the tangential velocity at its inner wall is at least about 18 meters per second;
• introducing water into the interior region of the permeable element, thereby causing the water to pass through the permeable element and be collected by the chamber, and
• causing steam to flow through the permeable element from its exterior to its interior region, thereby causing transfer of oxygen from the water to the steam.

A process for accomplishing heat and/or mass transfer between a liquid feed and a second fluid or for extracting a volatile component from the liquid feed, the process comprising:

• a) rotating a rotatable permeable element disposed within a chamber so that liquid feed introduced into the interior of the element permeates to the exterior of the element and is collected by the chamber, the rotatable permeable element, as a whole, having a porosity of less than about 40 pores per inch, the rotatable permeable element defining an inner wall and an interior region, the rotatable permeable element rotating at a speed such that the tangential velocity at its inner wall is at least about 18 meters per second;
• b) withdrawing liquid feed collected by the chamber, and
• c) withdrawing from the interior of the rotatable permeable element a second fluid which is introduced into the chamber from the exterior of the rotatable permeable element, or which is a volatile component recovered from the liquid feed.
