1) Off-Gas Circulation Process by our formaldehyde machine

Off-gas is used to take away the reaction heat instead of steam. Therefore, formaldehyde concentration is improved and steam is saved.

2) Flue Gas Circulation Process by our formaldehyde machine:

Flue gas resulted from off-gas incineration is employed to raise the yield as well as the run-up safety.

3) Incomplete Conversion Process

An excess of methanol is fed to reduce the reaction temperature and therefore our formaldehyde production line will lower the occurrence of side reactions as well as methanol consumption.

Low Consumption

1) Methanol Consumption: 440-445 Kg/t

2) Power Consumption: 25 KWh/t

Product Quality of our Formaldehyde production line

1) Formaldehyde Content: 37%-52%

2) Methanol Content: 0.2%

3) Acidity: 0.01%

4) 700-1000 Kg/t of steam as the by-product

Rational Plant Structure

Theformaldehyde equipmentsinclude only 3 parts: Evaporator-Reactor-Absorber. Others are either combined into the three or removed.
