Formaldehyde manufactured industrially by two reputation methods:
- By adding oxygen to the methanol structure. Carbon and hydrogen along with oxygen form water and the formaldehyde.
- By dehydrogenation of methanol hydrogen is removed from its structure leaving the formaldehyde. This is most economical due to its byproducts.
One unique integration process is most energy optimized, that is using two reactors each for oxidation and dehydrogenation. The heat developed from the oxidation reactor is used for dehydrogenation reactor and have generate high yield process. A process flowsheet developed with this ideology.
