某化工企业TMPTA车间废气治理系统改造工程实例

结合江苏某化工企业三羟甲基丙烷三丙烯酸酯(TMPTA)车间废气污染的监测和改造经验,总结了该废气污染特点,采用"一级低温水冷+气体捕集器+一级碱吸收+旋风除雾+活性炭纤维吸附回收装置"的综合治理技术有效控制了废气污染,并实现了甲苯的回收利用.采用的活性炭纤维吸附回收装置的设计风量为6000 m3/h,设计甲苯的流量为30 kg/h.改造设备总投资约为120万元,每年回收甲苯的总价值为136.8万元,运行费用约67.7万元.相关监测数据表明上述废气治理工艺在设备正常运行时可确保污染物达标排放.%Combined with the waste g as pollution monitoring and engineering experiences of a chemical factory TMPTA workshop in Jiangsu, the pollution characteristics of waste gas were analyzed. The combination process of "first-stage low temperature water cooling + gas trap + first-stage alkali adsorption + cyclone mist + activated carbon fiber adsorption unit"was used to treat the waste gas, the waste gas pollution was effectively controlled, and the recovery of toluene was realized. The designed air flow rate of the activated carbon fiber adsorption unit was 6000 m3/h, the mass flow rate of toluene was 30 kg/h. The total cost of the equipment was about 1.2 million yuan, the total value of the recovery of toluene is 1.368 million yuan each year, and the operating cost is about 0.677 million yuan each year. The data showed that during normal operation, the emission concentrations and rates of each kinds of waste gas could be lower than the value in the corresponding standards.

某香料化工企业废气综合整治提升工程研究

针对某香料化工企业废气收集差,治理难的问题,采用源头设备提升+过程收集完善+末端治理达标的治理模式,通过淘汰落后的生产设施,完善无组织废气的收集,实现无组织废气转变为有组织废气,废气收集风量由8000 m^(3)/h提升至15000 m^(3)/h,并最终选用了"水吸收+活性炭吸附-催化燃烧"治理工艺对有组织废气进行治理.经监测,整治前废气中非甲烷总烃排放浓度为70~120 mg/m^(3),整治后非甲烷总烃排放浓度为20~50 mg/m^(3),污染物去除率为90%,废气污染物排放满足《大气污染物综合排放标准》(GB 16297-1996),气味明显降低,废气治理设施年运行费用为23.2万元,取得了良好的整治提升效果.

某制药企业污水站废气收集与治理工程实例

某制药企业污水站运行期间,预处理及生化处理阶段会产生臭气,且存在挥发性有机物外溢问题.现根据污水站实际情况,分别采用玻璃钢盖板,反吊膜,耐力板对不同类型废水处理单元进行加盖改造,并采用玻璃钢风管收集废气.废气通过生物滤池处理系统及活性炭纤维吸附后,恶臭及非甲烷总烃达标排放,改造后整个工程运行成本降低,对同类型老旧制药企业废气治理升级改造具有借鉴价值.
