Does anyone know what types of wastewater are generated in the process of producing methanol from coke oven gas, how it is treated, and what the required standards are?
The wastewater generated in the production process mainly includes: gas treatment condensate, water from gas generation washing cycles, residues from methanol distillation, water from coal gas separation, and water used for workshop cleaning, among others.
Methanol production wastewater can be treated using biological methods, as it has a high BOD and contains carbon sources. For emission standards, it is necessary to determine specifically where the emissions are to be directed – whether **national standards** or local standards apply.
