Latest Patents

One of Huber's latest patents focuses on the production, purification, and polymerization of aromatic dicarboxylic acids. This invention provides a process for purifying crude aromatic dicarboxylic acids produced by the oxidation of dialkyl aromatic hydrocarbons. The purified acids can then be used in the preparation of polyethylene terephthalate, polyethylene naphthalate, and other polyesters. The invention simplifies the manufacturing process by converting crude aromatic acids into bis-glycol esters in an esterification reactor. The esterified partial oxidation impurities present in the oxidation product are removed by distillation in a distillation tower. After the removal of volatile impurities, the dicarboxylic acid esters can be separated by distillation or crystallization and converted to polyesters through polycondensation. The volatile impurities removed as overhead from the tower can be recycled back to the oxidation reactor, where they act as oxidation promoters, allowing for a bromine-free oxidation process for dialkyl aromatic hydrocarbons.

Another significant patent by Huber is a method and apparatus for increasing conversion efficiency and reducing power input in an agitated oxidation reactor. This innovation improves mixing performance by decreasing the clearance between the lowermost impeller element and the reactor bottom, while also providing a flat blade turbine as the upper impeller element.
