The improvements of gas venting processes for the dryers and the temperature & humidity regulator of the Acrylic Fiber Plant of Daqing Refining and Chemical Company are expounded.The 2 dryers are slightly different in processes,the pipelines connected to the 2 venting headers of the temperature & humidity regulators return to their respective venting zones,but the pipelines connected to the 2 venting headers of the dryers only return to zone 1;After 1 year since the equipment process flow modification,both the economic and environmental benefits have been gained.
