    摘要： Disclosed is a process to produce a purified carboxylic acid product. The process comprises removing impurities from a crude carboxylic acid slurry in a solid-liquid displacement zone to form a slurry product. The slurry product if further treated in a staged oxidation zone and a crystallization zone to from a crystallized product. The crystallized product is further cooled in a cooling zone and subsequently filtered and dried in a filtration and drying zone. The process produces purified carboxylic acid product having good color and low impurity levels without the use of purification steps like hydrogenation.

    摘要： Disclosed is a process of hydrogenating a polyester oligomer containing terephthalic acid residues wherein terephthalic acid residues are converted to residues of 1,4-cyclohexanedicarboxylic acid. Also disclosed is a process for the preparation of polyesters containing 1,4-cyclohexanedicarboxylic acid residues by first hydrogenating a polyester oligomer containing terephthalic acid residues and then reacting the resulting oligomer with one or more polyester-forming reactants to produce a higher molecular weight polyester.

    摘要： A system and method for assessing risk is provided. The method comprises determining an investment index associated with investment by an insurance company in an insurance pool. Next, the method comprises determining a return index associated with an expected return to the insurance company from participating in the insurance pool; and determining a benefit index based on the investment and return indices. The system for assessing risk comprises an assessment module for assessing risks associated with an insurance company's participation in an insurance pool based on at least one of: an investment index associated with the costs of participating in the insurance pool, and a return index associated with the benefits of participating in the insurance pool.

    摘要： Disclosed is an optimized process and apparatus for more efficiently producing aromatic dicarboxylic acids (e.g., terephthalic acid). In one embodiment the process/apparatus reduces costs by recovering and purifying residual terephthalic acid present in the liquid phase of an initial oxidation slurry. In another embodiment the process apparatus reduces costs associated with hydrogenation by forming a final composite product containing unhydrogenated acid particles.
