Guardbed Technology

A unique aspect of our bed design technology is its Active filtration System (AFS) bed protection filter disk grading technology.

A unique aspect of our bed design technology is its Active Filtration System (AFS) bed protection filter disk grading technology. This technology is used to filter fines in hydrotreating units, sulphur guard beds and chloride guard beds. By filtering out any solid particles, premature end of run pressure drop conditions can be prevented, therefore increasing the lifetimes of pressure-sensitive units.

Our guard bed catalysts are used in the protection of the main bed hydrotreating catalysts from arsine and silica poisoning alongside the prevention of pressure drop issues.
