ABSTRACT:
A process is provided for minimizing the deposition of materials like naphthalene and tar in the ammonia liquor coolers of the primary cooler in a by-product recovery process for coking carbonaceous materials. The ammonia liquor coming from the primary cooler, wherein it is used to cool the coke oven gas, has added to it light oil before it reaches the ammonia liquor coolers, where it is cooled indirectly with water. The addition of the light oil keeps the naphthalene and tar in solution at the lower temperatures of the ammonia liquor coolers, thereby reducing or preventing the deposition of the naphthalene and tar in the ammonia liquor coolers.
