Question: Utilization of condensed water in the system after the conversion of coke oven gas to methanol

In the process of producing methanol from coke oven gas, a conversion catalysis step is used to produce pure oxygen; 50% steam also enters the system along with the oxygen in the converter. After condensation, this steam goes into a vapor-liquid separator. Designally, this water can be recycled into the circulating water system, but it contains a certain amount of heavy metals and high levels of ammonia nitrogen, which can affect the proper operation of the circulating water system. Don’t know how to deal with it?
The conversion system at my plant uses wet air coolers; once operations are running normally, the condensate can be used to replenish water in these air coolers, and they can also be utilized for the air coolers in the synthesis and distillation processes. Use desalinated water when parking.
