Discussion on new operation conditions of oxidation reactor in pure terephthalic acid unit
The operation status of oxidation reactor in pure terephthalic acid unit is analysized.The principle of oxidation reactor and the process factors affecting the oxidation are presented especially.Based on the chemical engineering theory,the data provided by patentee and the data accumulated from operation,the methods for reducing acid consumption and enhancing producing load are discussed and checked in practical production.The results show that applying the operation conditions of low pressure,low solvent ratio and high catalyst concentration,the operation load can increase 25% and the acid consumption can reduce 10% without increasing investment.
