Overview:
A yet2 client is seeking improvements or alternatives to its existing gas-transfer technology that preferentially allows gas (rather than liquid) to be vented through a small porous channel upon pressure buildup on one side of a polymer material. The prospective permeable channel solution needs to be integrated into a larger polymer sheet, so there are several potential issues to consider:
- Creation of a reliable seal between the porous, or otherwise permeable, channel component and the polymer material
- Avoidance of liquid phase flow through and around the edges of the prospective permeable channel solution
- Avoidance of weakening the polymer part at the interface
Background:
The polymer in question will have a pressurized fluid on one side, and empty, but limited, space on the other. Gas can permeate through the polymer and enter the empty space, so a porous channel integrated into the polymer that preferentially allows gas transfer back to the fluid is used to avoid gas buildup in the empty space.
Constraints:
Technologies must:
- Be able to withstand temperatures between -20°C to +130°C
- Be able to withstand pressures up to 600 bar
- Resist chemical degradation from sulfur, hydrogen sulfide, biocides, methanol, and organic based chemicals
Possible Solution Areas:
- Filtration media
- Contaminant prevention processes
- Petrochemical industry
- Oil & Gas industry
- Laboratory processes
Desired outcome of the solution:
Identification of a technology that meets the desired parameters.
