Absorption of formaldehyde from gases containing it |
| abstract |
A PROCESS FOR THE ABSORPTION OF FORMALDEHYDE FROM GAS CONTAINING FORMALDEHYDE (OBTAINED IN THE DEHYDROGENATING OXIDATION OF METHANOL OVER SILVER CATALYSTS) AT ELEVATED TEMPERATURE IN A PLURALITY OF STAGES, WHEREIN THE GAS PASSES THROUGH AT LEAST THREE ABSORPTION STAGES AT TEMPERATURES OF FROM 60* TO ABOUT 90*C., PAARICULARLY FROM 70* TO 85*C., AND IS CONTACTED IN EACH OF THE STAGES FROM THE FIRST STAGE TO THE PENULTIMATE STAGE WITH AN AQUEOUS SOLUTION OF A UREA-FORMALDEHYDE PRECONDENSATE AND IN THE FINAL STAGE IS CONTACTED WITH AN AQUEOUS SOLUTION OF UREA. |
