Complete Solutions in sulfur recovery + processing
Matrix’s proprietary Devco II Process is a wet pelletizing process that offers single unit capacities ranging from 50 to 2,000 tons per day. 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 ensures 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.
Today, these units are being commissioned in Saudi Arabia and Alberta, Canada, and remains the technology of choice for safe sulfur forming operation in the United States, China, and Saudi Arabia.
