  • Patent number: 11135545
    Abstract: Provided is a gas separation device configured to separate a non-hydrocarbon gas from a feed gas containing the non-hydrocarbon gas through use of a gas separation membrane, in which a decrease in operating rate can be suppressed, and economic efficiency is satisfactory. A first membrane module (1) and a second membrane module (2) are arranged in parallel to each other with respect to supply lines for a feed gas. Gas lines for regeneration (14, 15) ((24, 25)), which are branched from a permeate gas line (13) ((23)) of the membrane module (1) ((2)), and which are joined to a feed gas line (21) ((11)) configured to supply the feed gas to the membrane module (2) ((1)), are provided. Under a state in which the feed gas is supplied to the membrane module (1), a permeate gas through the membrane module (1) is supplied, as a gas for regeneration, to the membrane module (2) through the gas lines for regeneration (14, 15).

  • Patent number: 11135541
    Abstract: This document presents an apparatus for a flexible air filter media that can be configured for shipping and storage having one or more flexible inserts mounted to the filter media along one or more portions of the accordion folds of the air filter material. The current invention permits the air filter apparatus to fold along both X and Y axes, create a tri-fold, and bend in a manner that provides for a much smaller volume for shipping purposes. The invention also permits attaching the flexible material to the center of the filter media and also inserts which allow sections of the air filter media to be nested one into another to reduce both shipping and storage volume.
