摘要： The invention provides improved energy content in and shaft power recovery from off-gas from xylene oxidation reactions while at the same time minimizing wastewater treatment cost. More shaft power is produced using off-gas than is required to drive the main air compressor, even with preferred, relatively low oxidation temperatures. Simultaneously, an amount of wastewater greater than byproduct water from oxidation of xylene is kept in vapor form and treated along with off-gas pollutants in a self-sustaining (self-fueling) gas-phase thermal oxidative destruction unit. Optionally, off-gas is combined from multiple xylene oxidation reactors, comprising primary and/or secondary oxidation reactors and forming TPA and/or IPA. Optionally, air compressor condensate and caustic scrubber blowdown are used in a TPA process or as utility water, effectively eliminating normal flow of liquid wastewater effluent from a TPA plant. Optionally, PET off-gas containing the water of PET formation is treated in a shared thermal oxidative destruction unit, effectively eliminating normal flow of liquid wastewater effluent from a combined pX-to-TPA-to-PET plant.
摘要翻译：本发明提供了来自二甲苯氧化反应的废气的改进的能量含量和轴功率回收，同时使废水处理成本最小化。即使使用优选的相对低的氧化温度，也可以使用除了驱动主空气压缩机所需的废气以外的更多的轴功率。同时，大量来自二氧化碳氧化的副产物水的废水保持蒸气形式，并在自持（自燃）气相热氧化破坏装置中与废气污染物一起处理。任选地，废气从包括初级和/或二级氧化反应器并形成TPA和/或IPA的多个二甲苯氧化反应器组合。任选地，空气压缩机冷凝物和苛性碱洗涤器排污用于TPA方法或作为效用水，有效地消除了来自TPA设备的液体废水流出物的正常流动。任选地，在共同的热氧化破坏单元中处理含有PET形成水的PET废气，有效地消除了从组合的pX到TPA到PET植物的液体废水流出物的正常流动。
