Patent number: 11911729Abstract: The present disclosure is directed ion-exchange systems and devices that include composite ion-exchange membranes having 3D printed spacers on them. These 3D printed spacers can drastically reduce the total intermembrane spacing within the system/device while maintaining a reliable sealing surface around the exterior border of the membrane. By adding the spacers directly to the membrane using additive manufacturing, the amount of material used can be reduced without adversely impacting the manufacturability of the composite membrane as well as allow for complex spacer geometries that can reduce the restrictions to flow resulting in less pressure drop associated with the flow in the active area of the membranes.Type: GrantFiled: January 18, 2023Date of Patent: February 27, 2024Inventors: Ethan L. Demeter, Michael James Connor, Jr., Chad Unrau, Brian M. McDonald

Publication number: 20240002260Abstract: Disclosed herein is a method for recovering water from a salt solution. The method can include mixing the salt solution with a salting out solution that includes at least one enolizable ketone and at least one alcohol. The salting out solution can absorb the water from the salt solution and the water can be released using a regenerant solution. A base solution can also be added to fully regenerate the salting out solution so that it can be reused.Type: ApplicationFiled: July 7, 2023Publication date: January 4, 2024Applicant: MIS IP Holdings, LLCInventors: Rachel Guia GIRON, Ethan L. DEMETER, Jeremy A. WILLMAN

Patent number: 11833474Abstract: The present invention provides a device capable of reducing the resistance and increasing the ion exchange rate in an electrodialysis, electro-deionization, or capacitive deionization apparatus and a method for producing said device. More specifically, the device is an electrodialysis spacer designed to have an ionically conductive surface of either cationic nature, anionic nature or a combination of both, which act as conductive pathways for ions as they move towards their respective electrode. The method of producing said spacer involves coating a substrate, such as a woven mesh, expanded netting, extruded netting or non-woven material, with perm-selective ionomer solutions and applying that substrate to an inert spacer material that has undergone chemical or mechanical etching.Type: GrantFiled: August 26, 2020Date of Patent: December 5, 2023Assignee: MIS IP Holdings, LLCInventors: Brian M. McDonald, Ethan L. Demeter

Publication number: 20230339794Abstract: Provided are water treatment systems for reducing hardness in water. The water treatment systems include an electrodialysis device comprising a brine inlet stream, a feed stream, a brine outlet stream, and a product outlet stream, and a template assisted crystallization (TAC) filter comprising a brine inlet stream and a brine outlet stream. The brine inlet stream comprises the brine outlet stream of the electrodialysis device and the brine inlet stream of the electrodialysis device comprises the brine outlet stream of the TAC filter. The system pressure is reduced by 30-60% when the brine stream goes through a TAC filter than a system without the filter. An acid supply and an acid feed stream may also be included, wherein the brine inlet stream of the electrodialysis device comprises the brine outlet stream of the TAC filter and the acid feed stream.Type: ApplicationFiled: March 15, 2023Publication date: October 26, 2023Applicant: MIS IP Holdings, LLCInventors: Ethan L.

Patent number: 11695122Abstract: A layered cathode structure for a molten carbonate fuel cell is provided, along with methods of forming a layered cathode and operating a fuel cell including a layered cathode. The layered cathode can include at least a first cathode layer and a second cathode layer. The first cathode layer can correspond to a layer that is adjacent to the molten carbonate electrolyte during operation, while the second cathode layer can correspond to a layer that is adjacent to the cathode collector of the fuel cell. The first cathode layer can be formed by sintering a layer that includes a conventional precursor material for forming a cathode, such as nickel particles. The second cathode layer can be formed by sintering a layer that includes a mixture of particles of a conventional precursor material and 1.0 vol % to 30 vol % of particles of a lithium pore-forming compound.Type: GrantFiled: November 26, 2019Date of Patent: July 4, 2023Assignees: ExxonMobil Technology and Engineering Company, FUELCELL ENERGY, INC.Inventors: Abdelkader Hilmi, Gabor Kiss, Rodrigo F.
