Tiem Aldajani has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Dehydration processes using membranes with hydrophobic coating
    Patent number: 9061252
    Abstract: Processes for removing water from organic compounds, especially polar compounds such as alcohols. The processes include a membrane-based dehydration step, using a membrane that has a dioxole-based polymer selective layer or the like and a hydrophilic selective layer, and can operate even when the stream to be treated has a high water content, such as 10 wt % or more. The processes are particularly useful for dehydrating ethanol.
    Type: Grant
    Filed: June 12, 2013
    Date of Patent: June 23, 2015
    Assignee: Membrane Technology and Research, Inc.
    Inventors: Yu Huang, Richard W. Baker, Tiem Aldajani, Jennifer Ly

  • Membrane augmented distillation to separate solvents from water
    Patent number: 8263815
    Abstract: Processes for removing water from organic solvents, such as ethanol. The processes include distillation to form a rectified overhead vapor, compression of the rectified vapor, and treatment of the compressed vapor by two sequential membrane separation steps.

  • Pervaporation assembly
    Patent number: 8123943
    Abstract: The invention is a pervaporation process and pervaporation equipment, using a series of membrane modules, and including inter-module reheating of the feed solution under treatment. The inter-module heating is achieved within the tube or vessel in which the modules are housed, thereby avoiding the need to repeatedly extract the feed solution from the membrane module train.
