Material issues in producing polyformaldehyde from methanol
Thread Content
This post was last edited by kongkongruye on 2009-9-8 17:12. How many steps are needed to produce polyformaldehyde from methanol? What is the approximate material consumption? How many tons of methanol and how many tons of steam are needed to produce 1 ton of formaldehyde? How many kilowatt hours of electricity? Prizes for answers! ! !
Not quite correct, just for reference: Serial number name specification unit consumption quota (ton 37% formaldehyde solution) consumption 1 Methanol industrial product t 0.46 2 Silver Kg 0.001 3 Nitric acid reagent grade Kg 0.015 4 Oxalic acid reagent grade Kg 0.05 5 Circulating cooling water 42~32℃ t 72 6 Deep well water 18℃ t 2.34 7 Soft water 25℃ t 1.36 8 Electricity 380V Kwh 30 9 Steam 0.4MPa t -0.18
