Abstract
PURPOSE: To eliminate conventional manual work for removing tar residue in circulating mother liquor and rationalize the work by treating the tar residue with a river sand-packed filter when ammonium sulfate is manufactured by recovering NH3 in coke oven gas with dil. sulfuric acid.
CONSTITUTION: Ammonium sulfate mother liquor circulating in NH3 saturator 1 is fed to slurry vessel 3 to separate supersatd. ammonium sulfate crystals in the liquor by settling. The ammonium sulfate crystal-free mother liquor and tar residue are allowed to overflow from vessel 3, and this overflow is supplied to river sand- packed filter 5 with filtration pump 4. In filter 5 the tar residue alone is allowed to be adsorbed on the sand, and tar residue-free ammonium sulfate mother liquor is taken out as the filtrate and returned to saturator 1 through the original liq. circulating system such as overflow vessel 6. Ammonium sulfate mother liquor in saturator 1 is drawn into sealed pot 7 and vessel 6 and circulated through a liq. circulating pump and a steam heater.
