Formaldehyde Haldor Topsoe process

Figure 5-6. The Haldor Topsoe and Nippon Kasel process for producing formaldehyde (1) blower, (2) heat exchanger, (3) reactor, (4) steam boiler, (5) absorber, (6,7) coolers, (8) Incinerator, (9) heat recovery, (10) methanol evaporator, (11) boiler feed water.

The Haldor Topsoe Formaldehyde SR process is well-suited to expand existing formaldehyde plants—up to 100% capacity increase may be achieved. 

Formaldehyde SR [Series Reactor] A process for making aqueous formaldehyde from methanol. Developed by Haldor Topsoe. Three plants had been built by 2005, and three more were under construction. 

Figure 3.22 shows a schematic of the Haldor-Topsoe A/S Formaldehyde Process. The process starting material is methanol and the catalyst used is Haldor Topsoe A/S FK-series iron/molybdenum-oxide catalysts [9]. The process is carried out in a recirculation loop at near atmospheric pressure (I—...
