摘　　要：醋酸单耗是PTA装置生产成本的主要衡量指标。降低氧化反应强度是降醋酸单耗的主要措施。此外,进一步减少排污量和污水中醋酸的浓度、减少进入催化氧化反应器中醋酸的浓度、减少母液回收中的醋酸损失也是显著降低醋酸单耗的重要措施。Acetic acid consumption is the main indication of the cost of PTA plant. Reducing the intensity of oxidation reaction is the main measure to reduce the unit consumption of acetic acid. In addition, further reducing sewage discharge and acetic acid concentration in sewage, reducing acetic acid concentration entering catalytic oxidation reactor and reducing acetic acid loss in mother liquor recovery are also important measures to significantly reduce acetic acid consumption.
