UREA FORMALDEHYDE CONCENTRATE
(UFC-85)
UNIQUE SERIES REACTOR SCHEME FOR AF-37 / UFC-85
SIMULTANEOUS PRODUCTION OF AF-37 / AF-55 / UFC-85
METAL OXIDE FORMALDEHYDE CATALYST
FK 2
/ FK 100 CATALYSTS |
ATEC recommends to load the Formaldehyde
Reactor tubes with the highly reactive & efficient Haldor Topsoe FK-2 Catalyst,
which has a loaded density of 0.8 Kg. / Litre.
The typical lifetime of HTAS –
FK2 Catalyst is above 33 months and Formaldehyde Production of upto 40 M.T. per Kg. of Catalyst. This is a
rugged Catalyst capable of delivering high conversion efficiency on sustained
basis over long periods.
Topsøe’s Formaldehyde
catalyst is of the Iron-Molybdenum type
in Raschig Ring Shape is used in the
Excess Air Process.
The catalyst is optimised for maximum yield and minimal
pressure drop and is appropriately diluted
in carefully recommended proportions with Porcelein Rings.
INCINERATION
CATALYST
CATALYTIC INCINERATION PROCESS IN FORMALDEHYDE PLANT
|
The catalytic incinerator
will be loaded with Haldor Topsoe CK
Catalyst. The typical lifetime of
CK Catalyst is more than 4 years.
The off gases from the Formaldehyde Plants are led to integrated catalytic incineration units. Here the
off-gas is preheated to 250ºC by heat exchange with surplus energy from the
Formaldehyde process, before it is purified in the Catalytic Reactor and emitted to the atmosphere, as shown below :
The purification process
results in a Formaldehyde emission below
5 mg/Nm³, while CO emissions are
lowered to less than 20 mg/Nm³. As
the purification is done at temperatures below 600ºC, the purification takes
place without formation of NOx.
ATEC’s
fully optimized process
design affords completely environmental friendly Formaldehyde Plants capable of
rendering “Zero Liquid Effluent
Discharge” and statutory compliant “Ambient
Emissions”.
