Abstract

PURPOSE: To reduce heat quantity supplied externally to the by-product ammonium sulfate process, by utilizing the sensible heat of the gas liquor sprayed in the ascention pipe of the coke oven gas and recycled through the tar curtain again to the ascention pipe.
CONSTITUTION: For example, in a by-product ammonium sulfate production system having an ammonium sulfate crystallizer, the coke oven gas is introduced through the pipe 1 to the NH3 saturator 2, and made to contact with the mother liquor sent through the pipe 7 from the tank 6 for recycling a mixture of sulfuric acid and water. The mother liquor containing produced ammonium sulfate is sent partly to the tank 6 through the pipe 5, and partly to the evaporator 14 through the pipe 9 after being heated with steam from the heater 13 together with the mothor liquor from the crystallizer 10. The mother liquor is boiled in the evaporator 14 under reduced pressure to evaporate the water, and the concentrated mother liquor is ejected into the crystallizer 10 while separating the crystel nuclei under super-saturated state. After sepnarating the crystals in the crystallizer, a part of the mother liquor is returned to the tank 6. The sensible heat of the circulating gas liquor is utilized by the heat exchange at the points AWD, etc. in the system.
