    摘要： A process for preparing modified polymer by withdrawing a slip stream of polymer melt from the discharge line of a continuous polymerization reactor, admixing in a highly modified polymeric additive into the polymer melt within the slip stream, then introducing the modifier containing slip stream late in the manufacturing process prior to the slip stream withdrawal point. The improved processes of the invention have particular utility for large-scale, continuous reactor where transitions and short production runs are economically prohibitive thereby limiting the product breath. The process is particularly suited for producing a family of copolyesters using a continuous melt phase production process.

    摘要： Integrated processes for making polyesters are disclosed, that include the steps of: (a) producing an aromatic polycarboxylic acid in a monomer production facility; (b) producing a polyester in a polyester production facility, wherein the producing of the polyester comprises the substeps of: (i) forming a polyester reaction medium comprising at least a portion of the aromatic polycarboxylic acid from the monomer production facility, (ii) subjecting at least a portion of the polyester reaction medium to one or more chemical reactions to thereby produce the polyester, (iii) heating the polyester reaction medium at one or more locations in the polyester production facility via indirect heat exchange with high-pressure steam, wherein the heating causes at least a portion of the high-pressure steam to condense and thereby provide pressurized condensed water, and (iv) flashing at least a portion of the pressurized condensed water to thereby produce lower-pressure steam; and (c) using at least a portion of the lower-pressure steam to provide thermal energy to the monomer production facility.

    摘要： A system for processing large quantities of a reaction medium while maintaining the reaction medium in sheets. The system includes a reactor having a plurality of vertically-spaced downwardly-sloped trays over which the reaction medium flows while it is subjected to reaction conditions. The slope of the trays increases downwardly to accommodate for the increased viscosity of the reaction medium while the reaction medium flows downwardly through the reactor. An upper portion of the trays have a uni-directional configuration, while a lower portion of the trays have a bi-directional configuration. Further, the orientation of flow across the uni-directional trays is rotated by 90 degrees in at least one location as the reaction medium flows down the uni-directional trays.

    摘要： A method reducing wastewater in a polyester-manufacturing plant includes a step in which ethylene glycol-containing composition from at least one of the chemical reactors is provided to a water separation column. The water separation column is kept within a predetermined temperature range such that any acetaldehyde present in the water separation column is substantially maintained in a vapor state. A waste-vapor mixture comprising one or more organic compounds is subsequently removed from the water separation column and combusted. The polyester-manufacturing plant optionally includes a spray condenser system having a heat exchanger such that the heat exchanger is contacted with a hot ethylene glycol composition derived from the water separation column when the heat exchanger needs cleaning. The polyester-manufacturing plant may be enclosed with a roof and walls such that rainwater is prevented from being contaminated with any organic chemicals present in the polyester-manufacturing plant.
