Publication number: 20230025056Abstract: The present invention relates to a support for a filtration membrane configuration formed with a first set of projections and a second set of projections in opposite directions. At least some of the first projections may be shaped with top areas forming contact face towards a filtration membrane configuration. The support for a filtration membrane may be formed with a first set of projections and a second set of projections in opposite directions, where at least some of the first projections are connected to a porous sheet forming support for said filtration membrane. The filtration membrane may be positioned directly on the porous sheet, or other in a sandwiched construction including other elements.Type: ApplicationFiled: December 15, 2020Publication date: January 26, 2023Applicant: Saltkraft ApSInventors: Jørgen Mads Clausen, Jan Eric Thorsen, Lars Storm Pedersen, Henrik Tækker Madsen, Steen Nissen

Patent number: 11231021Abstract: A process for generating power from a warm saline steam (1) obtained from geothermal sources. The process involves converting latent osmotic energy present in the stream (1) into an increase in the total pressure of said stream by passing through an osmotic pump unit (7). The stream is passed over a semi-permeable membrane (8) and a lower salinity steam (14) is passed over the other side of said membrane (8), such that the need for mechanical pumping in subsequent process steps is reduced.Type: GrantFiled: July 11, 2018Date of Patent: January 25, 2022Assignee: SALTKRAFT APSInventors: Henrik Tækker Madsen, Steen Søndergaard Nissen

Patent number: 11231020Abstract: A process for generating power from a warm saline steam (1) obtained from geothermal sources. The process involves extracting a warm saline stream (1) from an underground geothermal formation (2), reducing the temperature of the saline stream (1) by passing the stream through a thermal power unit (5) in which thermal energy present in the stream is extracted. The process also involves converting latent osmotic energy present in the stream into electricity by passing the stream through an osmotic power unit (7) comprising a semi-permeable membrane (8). The output stream (13) derived from passage through the osmotic power unit is injected into a second, different underground formation.Type: GrantFiled: July 11, 2018Date of Patent: January 25, 2022Assignee: SALTKRAFT APSInventor: Steen Søndergaard Nissen
