Abstract

A system which facilitates the reduction and recovery of components contained in the oxidation waste gas discharged from the manufacturing process of aromatic dicarboxylic acids and enables the recovery of the pressure of the waste gas as power energy in a relatively low temperature range (of 150°C or below), namely, a system integrated with the manufacturing process of aromatic dicarboxylic acids in which the recovered energy is used as the power for compressing the air to be used in the oxidation and the resulting low-pressure waste gas (0.1Kg/cm2G) is used in processing (such as drying or transporting) the formed dicarboxylic acid powder. The system comprises (1) subjecting oxidation waste gas to two-stage absorption in high-pressure absorption towers with acetic acid and water, (2) bringing the resulting waste gas into contact with an adsorbent to dehydrate the waste gas and form a dry waste gas, (3) recovering the pressure of the dry waste gas in a relatively low temperature range as power energy with a two-stage expansion turbine by using the steam (5Kg/cm2G) generated in the oxidation as the heat source, (4) circulating the components recovered from the oxidation waste gas to the reaction solvent recovery step and reusing them, (5) using the recovered power energy in the oxidation, and (6) utilizing the resulting low-pressure waste gas for the formed powder.
