A PROCESS FOR THE COOLING OF MOLTEN SULFUR AT A HIGHER TEMPERATURE TO MOLTEN SULFUR AT A LOWER TEMPERATURE WHICH COMPRISES INTRODUCING WATER INTO THE HOT MOLTEN SULFUR IN A QUANTITY CALCULATED TO TAKE UP ON EVAPORATION THE HEAT NECESSARY TO REDUCE THE TEMPERATURE OF THE SULFUR FROM THE HIGHER TEMPERATURE TO THE LOWER TEMPERATURE, AGITATING THE RESULTING MIXTURE TO DISTRIBUTE THE WATER THROUGHOUT THE SULFUR, AND BREAKING UP THE FORMED DROPLETS OF WATER ULTIMATELY TO A SIZE AT WHICH THE HEAT TRANSFERABLE THERETO ADDED TO THAT OF THE WATER CAUSES COMPLETE EVAPORATION OF THE WATER RATHER THAN ITS ENCASEMENT BY SOLIDIFIED SULFUR SHELLS FORMABLE BY THE COOLING EFFECT OF THE ENTRAPPED WATER.
