Description

Jiangsu Hengmao is China’s leading formaldehyde plant manufacturer, and formaldehyde technology is our core competitive product.
We have been engaged in silver contact formaldehyde machine production for *1 years, and have successfully commissioned more than **0 formaldehyde production lines in domestic China and abroad.
Formaldehyde plants of *0,**0 to **0,**0 TPA are available with silver catalyst regeneration unit on turkey /EPC basis.

 

Formaldehyde Plants Hengmao Provides

Flexible Processes

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: ******5 Kg/t

2) Power Consumption: *5 KWh/t

Product Quality of our Formaldehyde production line

1) Formaldehyde Content: *7%**2%

2) Methanol Content: 0.2%

3) Acidity: 0.*1%

4) *******0 Kg/t of steam as the by-product

Rational Plant Structure

The formaldehyde equipments include only 3 parts: Evaporator-Reactor-Absorber. Others are either combined into the three or removed.
