Publication number: 20240002245Abstract: A method for forming an insoluble adduct using an acidic medium is provided. A chemical process utilizes acidic media to change the solubility behavior of metal solutes. The method can utilize Group 1 soluble alkali metals but can also be extended to any other soluble salts discussed under the solubility rules. The insoluble salts can be Group 2 alkaline earth metals or other insoluble salts. The insoluble adduct can have the designation XYZ where X is a soluble metal from a metal hydroxide or a metal oxide, Y is an insoluble metal from an insoluble metal hydroxide or an insoluble metal oxide, and Z is the acid ion from an aqueous acidic media.Type: ApplicationFiled: September 12, 2023Publication date: January 4, 2024Applicant: CRYSTAPHASE PRODUCTS, INC.Inventors: UMAKANT PRAVINCHANDRA JOSHI, AUSTIN SCHNEIDER, BRADLEY GLOVER, JOHN N.

Publication number: 20200215524Abstract: A method for removing contaminants from a process stream that includes the use of reticulated material to filter the process stream. The reticulated material also facilitate process stream flow distribution in process units. The reticulated material can be packed with a void space between a substantial number of the reticulated material that can be varied to enhance filtration and flow distribution. The method of filtering also provides a method of removing contaminants leaving process equipment. The methods can be used on a variety of process streams and process equipment. The reticulated material can include ceramics, metallic materials, and chemical vapor deposition elements. The reticulated material can be of various shapes and sizes, and can also be catalytically active.Type: ApplicationFiled: January 6, 2020Publication date: July 9, 2020Applicant: Crystaphase International, Inc.Inventors: JOHN N.
