Abstract
Hot gases containing naphthalene and tar together with the possible inclusion of solids are contacted in a spray tower with water to cool the gases. A naphthalene extraction agent, such as tar, is vigorously admixed with water withdrawn from the spray tower. The admixture is separated in a settling tank from which water is obtained and recycled to the spray tower for cooling further quantities of gases. Solids, gas condensate and tar enriched with naphthalene are separately removed from the settling tank.
