Silicon tetrafluoride ticks all the boxes.  It’s a colourless, highly corrosive, highly fouling and highly toxic gas.  It is released when phosphate ores are immersed in hot sulphuric acid and must be removed from various vent streams throughout the phosphate fertilizer manufacturing process.

This is achieved by exposing it to moisture which ironically, converts it to two even nastier – albeit more manageable – substances; hydrofluoric acid and silica oxide.

Jord designed and constructed three cross flow mesh pad scrubber systems to handle the 300,000 Am3/hr total flowrate of the vent gas streams.  Special care was taken with materials of construction and fabrication techniques to ensure this toxic gas would be 100% contained throughout the design life of the plant, ensuring operator safety at all times.
