General
- Formaldehyde is a chemical
compound with the formula H2CO.
- It is the simplest
aldehyde—an organic compound containing a terminal carbonyl group
- Formaldehyde is an
intermediate in the oxidation (or combustion) of methane as well
as other carbon compounds, e.g. forest fires, in automobile
exhaust, and in tobacco smoke.
Process
-
The evaporated methanol, filtrated air and
steam are fed into the mixer where theses gases are mixed
uniformly, and then sent to reactor.
-
Most of the methanol is converted into
formaldehyde when the mixed gas passes through the catalyst.
-
This reacted gas is immediately quenched in the
waste heat boiler integrated with the reactor.
-
At the same time, the waste heat boiler
recovers reaction heat to generate stem, which is effectively used
as heat sources for the methanol evaporator and other heaters, and
as stem supply for the mixer.
Market
-
Formaldehyde is used in Western Canada to make resins for wood
panels such as oriented strand board and medium density
fibreboard.
-
These
resins are produced close to the wood panel plants and the resin
plant usually include a formaldehyde plant.
-
Another use is in urea granulation. Agrium Inc, Kenai, Redwater
and Edmonton, Saskferco, Belle Plaine, and Canadian Fertilizers,
Medicine Hat, each use about 3,000 t/y.
Application
-
Formaldehyde is
an important chemical used widely by industry to manufacture
building materials and numerous household products.
-
In homes, the
most significant sources of formaldehyde are likely to be pressed
wood products made using adhesives that contain urea-formaldehyde
(UF) resins.
-
Formaldehyde-based solutions are used in embalming to disinfect
and temporarily preserve human remains.
-
It is the
ability of formaldehyde to fix the tissue that produces the
tell-tale firmness of flesh in an embalmed body.
-
Formaldehyde
derivatives serve a wide variety of end uses such as wood
products, plastics, and coatings.
