Valve and method for aqueous systems |
| abstract |
A valve is disposed in a line carrying an aqueous stream, the valve in the form of a permeable bed of particulate swellable polymer particles which imbibe organic materials and on contact therewith will swell to provide a positive shut-off and a polymeric structure which collapses on contact with organic liquid is disposed upstream of the permeable bed. Flow rates can be obtained which are higher than the flow rates with polymer particles alone. |
