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.

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 :

ATEC’s fully optimized process design affords completely environmental friendly Formaldehyde Plants capable of rendering “Zero Liquid Effluent Discharge” and statutory compliant “Ambient Emissions”.
