What is the appropriate water content in crude methanol produced from coal? When producing methanol from coal as raw material, what is an appropriate water content in the crude methanol?
In coal-to-methanol production, the level of CO2 in the syngas determines the water content in the crude methanol. The water content in crude methanol is 2%-8%. It is generally desirable to keep the CO2 content within the range of 2-4%. Typically, when the CO2 content is 1%, the water content in crude methanol is around 1.85%; when the CO2 content is 4%, the water content in crude methanol is around 6.5%.
A low water content means a low CO2 content in the fresh gas, which affects the proper operation of the catalyst. Additionally, there is also a risk of wax formation.
What is the moisture content when carbon dioxide is generally controlled at 5%? I’d like to ask for advice
Control such high CO2 levels? The CO2 level in low-pressure methanol is kept below 3%; CO2 is used only to control the reaction
Is the reaction heat of the methanol synthesis tower controlled?
It is used to control the heat generated during the reaction in the synthesis tower; since methanol synthesis is an exothermic reaction, by maintaining the proper reaction conditions, the reaction can be properly controlled, and the heat generation will also be suppressed
