Component removal from a gas
11318417 · 2022-05-03 · ·

A device, system, and method for removing a component from a gas are disclosed. A bead consisting of a core and an outer layer is provided. The outer layer consists of a first impermeable material. The core consists of a second material. A carrier gas, containing a vapor, is passed across the bead, desublimating or desublimating and condensing a portion of the vapor onto the bead. In some embodiments, the beads are passed into the column at a first temperature and the carrier gas is passed across the beads. A portion of the vapor desublimates or desublimates and condenses onto the beads as a solid product, causing the beads to expand in volume as they are warmed to a second temperature. The beads with the solid product are passed out of the column.

Method of producing a cooled syngas of improved quality

A system and method for processing unconditioned syngas first removes solids and semi-volatile organic compounds (SVOC), then removes volatile organic compounds (VOC), and then removes at least one sulfur containing compound from the syngas. Additional processing may be performed depending on such factors as the source of syngas being processed, the products, byproducts and intermediate products desired to be formed, captured or recycled and environmental considerations.

Plasma abatement of compounds containing heavy atoms

A plasma abatement process for abating effluent containing compounds from a processing chamber is described. A plasma abatement process takes gaseous foreline effluent from a processing chamber, such as a deposition chamber, and reacts the effluent within a plasma chamber placed in the foreline path. The plasma dissociates the compounds within the effluent, converting the effluent into more benign compounds. Abating reagents may assist in the abating of the compounds. The abatement process may be a volatizing or a condensing abatement process. Representative volatilizing abating reagents include, for example, CH.sub.4, H.sub.2O, H.sub.2, NF.sub.3, SF.sub.6, F.sub.2, HCl, HF, Cl.sub.2, and HBr. Representative condensing abating reagents include, for example, H.sub.2, H.sub.2O, O.sub.2, N.sub.2, O.sub.3, CO, CO.sub.2, NH.sub.3, N.sub.2O, CH.sub.4, and combinations thereof.
