| Abstract: | Organic materials in tail gas are recovered in EPTA plant during the production process of medium terephthalic acid.The consumption of PX and AcOH is analysed.The tail gas disposal process is modified.70% of methyl acetate and 92% of PX are recovered by absorbing and distillation.The unit consumption is reduced by 3.33 kg/t,2.09 kg/t for PX and AcOH respectively;and 2.02 kg/t methanol is obtained. |
