This article discusses the influence of urea prilling tower exit temperature on the water percentage of urea,analyses the factors influencing urea prilling tower exit temperature,and puts forowrd suggestions to control the tower exit temperature through replacing the prilling sprayer and adjusting the shutter opening of prilling tower according to atmosphere temperature and humidity.

Effecting factors of urea equipment corrosion were discussed from aspects of temperature,ammonia/carbon ratio,water/carbon ratio,ammonium formate solution concentration,oxygen content,sulfur content,chlorion content,medium velocity etc.

Granulation processes for the soluble granulates of 95%acephate,based on lab-scale experimental work,have been successfully scaled up by evaluating granulation equipment and investigating manufacture processes such as mixing process.
