Most air pollution regulations can be met by existing technology available.However, technology has not yet been developed to cope with the particulate emission problems at urea prilling towers. Considerable technical effort is being devoted to finding solutions to the prilling tower problems.One possible solution for new plants is to granulate urea in equipment which is amenable to particulate emission abatement. There are some unsolved water pollution problems at fertilizer plants awaiting further development of abatement technology.The following paper is case study of pollution control through prilling tower and other equipment in urea plant.
