Absorption
The Absorption Column has been optimized in order to satisfy the absorption and purification function of the gas stream resulting from the reaction.
In this equipment high efficiency structured packing and random rings are installed so to maximize contact between liquid and gas. In the washing section there are special packing that allow a high contact between the gas and washing liquid.
Compared to absorption column that make use of tray coils and perforated trays, MAPCO ENGINEERING Absorption Column has less pressure drops and avoids the long and expensive maintenance interventions to eliminate serious fouling that can occur mainly in high concentration UFC production.
Moreover MAPCO ENGINEERING Plant does not require any periodical washing and thus do not require any production stops that reduce the effective plant capacity.
The removal of absorption heat is made by means of external circulation of formaldehyde solution cooled in Plate Heat Exchangers by means of cooling water.
The cooling system has been designed with the objective to quickly drop the temperature and to have better approaches to the wet bulb temperature.
