Patent number: 11746639Abstract: The invention discloses a method of solution mining trona by injecting an aqueous solvent into an underground cavity comprising trona to dissolve trona in the aqueous solution and removing the aqueous solution from the cavity at about the WTN triple point (the temperature at which solid phase wegscheiderite, trona, and nahcolite can co-exist in an aqueous solution). Alkaline values from the removed aqueous solution are recovered to produce a barren liquor. The method further includes either (i) treating the barren liquor to produce an aqueous solvent or (ii) treating injected aqueous solvent to reduce clogging at the trona dissolution surface caused by supersaturation of sodium bicarbonate, and precipitation of nahcolite and wegscheiderite as the aqueous solution in the cavity approaches saturation of both dissolved sodium bicarbonate and sodium carbonate.Type: GrantFiled: August 11, 2021Date of Patent: September 5, 2023Assignee: SESQUI MINING, LLC.Inventors: Roger L. Day, James A. Herickhoff

Patent number: 11028368Abstract: An improved cryopreservation process and substances can involve a cellular collection (1) in a cryopreservation fluid (4) that has been conditioned or treated (7) to enhance the cryopreservation process by adding (18) energy (19) such as in the surface energy of a substance in the cryopreservation fluid (4) prior to reducing energy for that same cryopreservation media for freezing. This can offer enhanced-post-cryogenic viability of the cryopreserved structures or a more optimum cooling curve (22) for a specific cell type.Type: GrantFiled: March 11, 2013Date of Patent: June 8, 2021Assignee: Membrane Protective Technologies, Inc.Inventors: Lisa A.

Patent number: 9260918Abstract: Disclosed are methods for solution mining of evaporite minerals, such as trona, comprising drilling an access well and at least two lateral boreholes; injecting a fluid; circulating the fluid through the lateral boreholes with a controlled fluid flow; and collecting a pregnant solution. Also disclosed are methods of solution mining that include injecting an aqueous solution into an underground trona cavity at a temperature sufficient to maintain at least a portion of the solution in the cavity in the Wegscheiderite solid phase region; removing aqueous solution from the cavity; and recovering alkaline values from the removed aqueous solution. Also disclosed are methods of solution mining that include injecting an aqueous solution into an underground trona cavity; removing aqueous solution from the cavity, wherein the temperature of the removed aqueous solution is at about the TWA point temperature; and recovering alkaline values from the removed aqueous solution.Type: GrantFiled: October 28, 2014Date of Patent: February 16, 2016Assignee: Sesqui Mining LLC.Inventors: Roger L.
