  • Purified terephthalic acid (PTA) vent dryer vapor effluent treatment
    Patent number: 10399921
    Abstract: Processes for manufacturing a purified aromatic carboxylic acid include contacting crude aromatic carboxylic acid with hydrogen in the presence of a catalyst in a hydrogenation reactor to form a purified aromatic carboxylic acid; separating vapor effluent from the purified aromatic carboxylic acid; scrubbing the vapor effluent to form a scrubber effluent; treating the scrubber effluent vapor to form a gaseous treated scrubber effluent and a liquid treated scrubber effluent; and removing at least a portion of organic impurities from the liquid treated scrubber effluent.
    Type: Grant

  • METHOD FOR FORMING AN AROMATIC DIACID AND/OR AN AROMATIC DIACID PRECURSOR FROM A POLYESTER-CONTAINING FEEDSTOCK
    Publication number: 20160326335
    Abstract: A method for forming an aromatic diacid and/or an aromatic diacid precursor from a polyester-containing feedstock. The method comprises contacting the polyester-containing feedstock with water or an alcohol to depolymerize the polyester and thereby form an aromatic diacid and/or an aromatic diacid precursor, wherein the polyester-containing feedstock comprises about 80 wt % or more polyester and about 1 wt % or more of at least one secondary material, and wherein the at least one secondary material is not polyester.
