What should be the minimum temperature of the material entering the formaldehyde absorption tower?

2017-01-17View Original

Thread Content

In the process of producing formaldehyde from methanol, the material leaving the reactor enters an absorption tower; therefore, a high inlet temperature for this tower is required in order to prevent the polymerization of formaldehyde in the gas phase. What is a reasonable temperature range for this value? For example, what is the minimum temperature it should not fall below?
