What is the function of the 1# alkali treatment tank in the coal-based ethylene glycol production process?
To neutralize HNO3 in the nitration-reduction reaction?
The feed pipelines for Tank 1# for alkali treatment total 6, coming from different locations; therefore, their specific purposes are unknown
Generally, an acid and alkali tank area is provided in the ethylene glycol system. The alkali refers to caustic soda, which is used in the following areas: 1. For DMO use, to neutralize the nitric acid waste liquid in the nitric acid treatment tank after the NOX generator； 2. DMO distillation, used in exhaust gas absorption towers. 3. For ethylene glycol dealdehydeization ； 4. For DMO tank area use
