Formaldehyde Production Methods

The pictures below are the panorama and equipment photos of the Formaldehyde Plant. SL TECH provide formaldehyde plant, welcome contact us for more information.

Almost all of the industrial synthesis of methanol by catalytic pressure of carbon monoxide hydrogenation process, including gas, synthetic purification, methanol synthesis and crude methanol distillation process; (crude methanol purification process, including distillation and chemical treatment. Chemical treatment Alkalis is mainly used to destroy impurities which are hard to be separated in the rectification process and to adjust the pH. Distillation is mainly for the removal of volatile components such as dimethyl ether and the less volatile components of ethanol, higher alcohols and water. Purity generally up to 98%.)

The industrial methanol distillation method will reduce the water content below 0.01%. Then sodium hypochlorite treatment, which can remove acetone. The pure methanol distillation;

General industrial methanol as raw materials, pressure distillation to remove moisture, control the top 64 ~ 65 ℃, filtered to remove insoluble matter;

Also available from the distillation of wood obtained when the pyroligneous acid;

The preparation of methanol is mainly used distillation process. To industrial methanol as raw material, the distillation, ultra-clean filter, clean packaging, high-purity methanol products.
