Abstract: A method of forming a gas treatment element for use in a gas treatment apparatus, such as a desiccant dryer, is disclosed. The element is formed by casting a sheet material by phase inversion of a dope mixture including a solvent, an adsorbent material such as a desiccant and a polymer binder. Layers of the sheet material are located adjacent one another and this is most readily achieved by rolling the sheet material to form the gas treatment element.

Abstract: A fume extractor system and method for use with a 3D printer includes a system operable in three conditions including: continuously filtering particulates and fumes at high temperatures during a printing process without intentional removal of pressure from the print chamber; continuously filtering particulates at high temperatures during a print process with intentional removal of pressure from the print chamber, to keep noxious gases retained in the print chamber; and purging the print chamber of fumes and mixing in ambient air to cool the fumes to a temperature low enough to allow adsorption of the fumes created by the printer. The system has a first compartment holding a first filter assembly and a second compartment holding a second filter assembly.

Abstract: A modified natural sulfide ore material, a preparation method, and a use thereof are disclosed. A natural sulfide ore and a copper salt are used as raw materials. The natural sulfide ore is modified through mechanical grinding for activation, drying, and the like to synthesize a sulfide ore composite. The copper salt is subjected to a reaction to increase metal sites, produce fine microcrystalline particles, and change the crystal structure, such that active sites can be fully exposed. When contacting mercury in a gas phase and/or a liquid phase, the modified natural sulfide ore material can convert the mercury into a stable compound to realize the immobilization and removal of the mercury, which has advantages such as large mercury adsorption capacity, high adsorption rate, wide application temperature range, low cost, abundant raw material reserves, simple operation, and environmentally-friendly mercury removal products without secondary pollution and shows promising industrial application prospects.

Abstract: Sorbent compositions, comprising a solid sorbent, a dispersive agent, and optionally a capture agent for enhanced wet-Flue Gas Desulfurization (wFGD) or wet scrubber unit function in a flue gas pollutant control stream is disclosed. The sorbent composition may include a sorbent with a dispersive agent, designed to enhance the dispersion of the sorbent in an aqueous sorption liquid of a wet scrubber unit, and therefore may be especially useful in EGU or industrial boiler flue gas streams that include one or more wet scrubber units. The sorbent composition may also include a capture agent useful in sequestering mercury and bromine, as well as other contaminants that may include arsenic, selenium and nitrates.

Abstract: This invention relates to a dispersion comprising porous particles dispersed in a liquid phase, wherein the porous particles comprise a zeolite and the liquid phase is a size-excluded liquid. The invention also relates to a method of adsorbing a gas into a liquid, comprising at least the step of bringing the gas into contact with the dispersion. In addition, the invention relates to an assemblage of the dispersion, the zeolite comprising a cavity and a gas contained within the cavity.
