Formaldehyde, driving, tempering!
Thread Content
Dear experts on formaldehyde, what is the cause of backfire during the operation of formaldehyde production? What measures should be taken?
It may be caused by low pressure due to small amounts of air and methanol feed. In such cases, tempering can increase the amount of steam added
It is caused by an excess of air; the amount of air should be reduced, steam for the ingredients should be added promptly, and the fan should be stopped as well as the methanol supply once the temperature drops.
I’ve learned something new, thank you. Does this approach also apply to the ferro-molybdenum method, or does it apply to all methods?
