Replies are rewarded – discussions are welcome. ---------------------------------------------------------- China National Chemical Corporation’s Tianchen Qixiang has recently seen the successful commissioning of its first butadiene-based adiponitrile production facility. The 711 Institute provided two sets of HCN waste gas incinerators for this facility, which are used to burn the HCN waste gas generated by the main units and to recover waste heat. The commissioning of this project successfully broke the technical monopoly held by foreign incinerator suppliers in the adiponitrile sector.

Organic waste gases: The main sources of organic waste gases are synthesis processes, refining steps, catalyst activation and deactivation, as well as the breathing action of storage tanks. The breathing exhaust gases generated by the HMD product tank and the ADN intermediate tank, as well as the exhaust gases produced during the loading and unloading of HMD into tank trucks, are collected through sealed pipelines and then sent to two-stage exhaust gas scrubbers for treatment, before being released through exhaust stacks. In emergency situations and abnormal operating conditions such as plant shutdowns, fluctuations or abnormalities in production, start-up and shutdown inspections and maintenance, as well as repairs, failures or shutdowns of the thermal oxidizer, the amount of waste gas may exceed the processing capacity of the thermal oxidizer. In such cases, the waste gas is routed through the safety high-pressure interlock system to be sent to a flare for treatment before being discharged.
