Patent number: 11666862Abstract: A membrane distillation apparatus includes a housing and an impeller. The housing includes a hot medium compartment, a cold medium compartment, an air gap compartment, a membrane, and a thermally conductive plate. The hot medium compartment includes a hot medium inlet configured to receive a hot medium stream including water. The cold medium compartment includes a cold medium inlet configured to receive a cold medium stream. The membrane defines pores that are sized to allow water vapor originating from the hot medium stream to pass from the hot medium compartment through the membrane to the air gap compartment. The thermally conductive plate and the cold medium stream are cooperatively configured to condense the water vapor from the hot medium stream. The air gap compartment is substantially filled with air and includes a permeate outlet configured to discharge the condensed water vapor. The impeller is disposed within the air gap compartment.Type: GrantFiled: November 10, 2020Date of Patent: June 6, 2023Assignee: King Fahd University of Petroleum & Minerals, Saudi Arabian Oil CompanyInventors: Dahiru Umar Lawal, Mohammed Abdul Azeem, Turki Nabieh Baroud, Atia Khalifa, Hasan Al Abdulgader

Patent number: 9335233Abstract: Leak detection system. The system includes a structure sized to fit within a pipe for supporting at least one sensing element near an inside wall of the pipe, whereby a pressure gradient at a leak in the pipe will cause the sensing element to respond. Structure is provided for detecting movement or deformation of the sensing element, the movement or deformation indicating the presence of a leak. In a preferred embodiment, the structure includes two spaced-apart rings for supporting the at least one sensing element. The sensing element is a diaphragm in a preferred embodiment. In this embodiment, the sensing element is supported for movement with respect to the ring structure which includes sensing circuitry for detecting the movement to indicate a leak. Other embodiments employ different sensing elements that respond to pressure gradients near leaks.Type: GrantFiled: April 27, 2011Date of Patent: May 10, 2016Assignees: Massachusetts Institute of Technology, King Fahd University of Petroleum and MineralsInventors: Atia Khalifa, Rached Ben-Mansour, Kamal Youcef-Toumi, Mohamed A. Habib, Dimitrios Chatzigeorgiou

Patent number: 9285290Abstract: Leak detection apparatus for deployment in a pipe. The apparatus includes a carrier disposed for motion along the pipe and a detector connected to move with the carrier in an axial direction. The detector comprises a drum mounted for rotation about pitch and yaw axes. A flexible material is mounted on, and extends from, the drum and at least two sensors responsive to drum rotation are provided. The flexible material will be drawn into contact with a wall of the pipe at a leak location, thereby producing a torque on the drum, causing the drum to rotate, and the at least two sensors to generate signals from which leak location is determined.Type: GrantFiled: November 5, 2013Date of Patent: March 15, 2016Assignees: Massachusetts Institute of Technology, King Fahd University of Petroleum and MineralsInventors: Dimitrios Chatzigeorgiou, Samir Mekid, Rached Ben-Mansour, Atia Khalifa, Kamal Youcef-Toumi

Patent number: 8869599Abstract: Leak detection system. A rigid body is resiliently supported within an outer cage. Structure is provided for detecting displacement of the rigid body with respect to the outer cage, the displacement indicating a leak when the rigid body is moved by a suction force generated by a local pressure gradient resulting from a leak within a pipe network. The invention allows a leak to be determined around the circumference of a pipe.Type: GrantFiled: January 23, 2012Date of Patent: October 28, 2014Assignees: Massachusetts Institute of Technology, King Fahd University of Petroleum & MineralsInventors: Rached Ben-Mansour, Dimitrios Chatzigeorgiou, Atia Khalifa, Changrak Choi, Kamal Youcef-Toumi

Publication number: 20130199272Abstract: Leak detection system. The system locates leaks in a pipeline that includes RFID tags deployed at known locations along the pipeline. A pair of bodies tethered to one another a fixed distance apart travels along the pipeline. Each of the bodies is supported for movement substantially along the centerline of the pipeline and each body includes a sensor responsive to sound or pressure variations generated by a leak. Signals are correlated to identify the existence of a leak. Each body also includes an RFID reader for reading the RFID tags in the pipeline. At least one of the bodies includes a power supply and/or electronics that are adapted to correlate signals from sensor on each body to determine the location of a leak within the pipeline.Type: ApplicationFiled: February 2, 2012Publication date: August 8, 2013Applicants: King Fahd University of Petroleum and Minerals, Massachusetts Institute of TechnologyInventors: Atia Khalifa, Rached Ben-Mansour, Yehia Khulief, Samir Mekid, Kamal Youcef-Toumi
