Production of free flowing paraformaldehyde |
| abstract |
PROCESS FOR THE PRODUCTION OF A FREE FLOWING PARAFORMALDEHYDE PRODUCT WHICH COMPRISES SPRAYING A LIQUID FORMALDEHYDE CONCENTRATE CONTAINING 85 TO 90% BY WEIGHT OF FORMALDEHYDE IN THE FORM OF DROPLETS INTO THE UPPER PORTION OF A COOLING TOWER SUPPLYING A COOLING INERT GAS AT A TEMPERATURE WHICH IS BELOW +39*C., AND PREFERABLY BETWEEN -40 AND +30*C., TO THE COOLING TOWER AND PASSING IT UPWARDLY THERETHROUGH, PERMITTING THE DROPLETS TO SOLIDIFY AS THEY DROP THROUGH THE RISING GAS BEFORE THEY REACH THE BOTTOM OF THE TOWER AND WITHDRAWING THE SOLIDIFIED PARTICLES FROM THE BOTTOM OF THE TOWER. PREFERABLY A FLUIDIZED BED OF SOLIDIFIED PARAFORMALDEHYDE PARTICLES IS MAINTINED IN THE BOTTOM PORTION OF THE TOWER AND THE SOLIDIFIED PARTICLES ARE FURTHER COOLED AFTER REMOVAL FROM THE TOWER. |
