Patent number: 9643102Abstract: The humidification-dehumidification desalination system includes a humidifier, a dehumidifier, and a carrier gas that is humidified in the humidifier and condensed in the dehumidifier to produce purified water. The humidifier preferably includes multiple stages in a staircase configuration in which at least one stage has a perforated or porous plate and the carrier gas is bubbled through the bottom of the plate into the “liquid to be purified” atop the plate. The dehumidifier may also include multiple stages in a staircase configuration in which at least one stage has a perforated or porous plate and the carrier gas is bubbled through the bottom of the plate into the purified liquid atop the plate. In both the humidifier and the dehumidifier, the liquid travels downward from one stage to the next stage. The system may be operated in a closed loop, so that the carrier gas is recirculated from the dehumidifier to the humidifier.Type: GrantFiled: June 5, 2014Date of Patent: May 9, 2017Assignee: KING FAHD UNIVERSITY OF PETROLEUM AND MINERALSInventors: Fahad A.

Publication number: 20110047924Abstract: The hollow brick providing thermal insulation is a construction block having a relatively high R-value. The hollow brick providing thermal insulation includes a main brick body forming a substantially rectangular prism. The main brick body has opposed upper and lower surfaces, a pair of laterally opposed sidewalls and a pair of longitudinally opposed sidewalls. A plurality of open passages are formed through the main brick body and extend between the upper and lower surfaces thereof. Each open passage defines upper and lower open ends formed through the upper and lower surfaces. The plurality of open passages are arrayed to form a plurality of laterally extending rows and a plurality of longitudinally extending columns. A longitudinal thickness between adjacent ones of the open passages in each longitudinally extending column is greater than a lateral thickness between adjacent ones of the open passages in each laterally extending row.Type: ApplicationFiled: September 1, 2009Publication date: March 3, 2011Inventors: Mohamed A.
