摘　　要：目前,某间苯二甲酸装置氧化料仓输送过程产生的废气均直接排放大气中,废气的有害成分主要为醋酸。废气中醋酸浓度远超《炼油与石油化学工业大气污染物排放标准》(DB 11/447—2015)的排放限值,即醋酸排放浓度应小于20 mg/m^(3)。根据废气排放特点,在分析和对比治理方法的基础上,最终选择碱液吸收法处理含醋酸废气。经碱洗塔水力学计算,对设备规格和材质等进行设计,使废气经处理后实现达标排放。At present,the waste gas generated during the transportation process of the oxidation material bin in a certain phthalic acid plant is directly discharged into the atmosphere,and the harmful component of the waste gas is mainly acetic acid.The concentration of acetic acid in the waste gas far exceeds the emission limit of the Atmospheric Pollutant Emission Standards for the Refining and Petrochemical Industry(DB 11/447—2015),which means that the acetic acid emission concentration should be less than 20 mg/m^(3).Based on the characteristics of waste gas emissions and the analysis and comparison of treatment methods,the alkaline absorption method is ultimately chosen to treat acetic acid containing waste gas.Through the hydraulic calculation of the alkali washing tower,the equipment specifications and materials are designed to achieve standard emissions of waste gas after treatment.
