The Devco II Process
In 1980, Devco investigated over fifteen different forming processes before deciding to use a wet prilling (also referred to as pelletizing) process for installation in Saudi Arabia. The wet process is very simple to operate, with low capital and operating costs, and is environmentally friendly. The small amount of moisture adhering to the surface of the pellets during the process insures that there will be minimal sulfur dust formed in the handling of the pellets, virtually eliminating the potential of fire or explosion sometimes associated with a dry process.
Devco has made numerous improvements in the wet pelletizing process it now offers. Single unit capacities range from 50 to 2,000 tonnes per day.
