Through the acquisition of Devco USA and Houston Interests, Matrix PDM Engineering has become the world leader in sulfur forming and handling technology. Our core capabilities include sulfur forming, facility design, sulfur blocking (long-term storage), sulfur melting, conceptual engineering, and operations expertise.

In sulfur recovery, processing and handling, our teams provide leading expertise and proprietary technology to convert molten sulfur into solid granules. Downstream, they also bring expertise in sulfur removal from gas streams and re-melting of sulfur granules for industrial use.

The sulfur forming facilities and product, plus downstream handling systems meet rigid environmental and safety requirements while delivering a much lower total cost of ownership than
competing technologies.

Our core expertise includes:

  • Sulfur forming
  • Facility design
  • Sulfur blocking (long-term storage)
  • Sulfur melting
  • Conceptual engineering
  • Operations expertise

Proprietary sulfur recovery, processing and handling technology

When Matrix PDM acquired Devco USA in 2016, it acquired it’s Devco II Process– its proprietary wet pelletizing process that offers single unit capacities ranging from 50 to 2,000 tonnes per day.

In 1980, Devco investigated 15  different forming processes before deciding to use a wet prilling or 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.
