Catalyst Protection Systems

Skid mounted purification packages

The use of guard beds or regenerative adsorbents is most often the best available option to solve the problems encountered in impurity management.  

Axens offers tailor-made, turn-key, skid-mounted purification packages based on state-of-the-art adsorbents. Single-source project management comprising engineering, procurement, fabrication and on site supervision is a key factor for these fast-track projects. Axens lays the foundations for time and money savings in impurity management.

EquiFlow® Hy-Clean™

To tackle pressure drop issues, Axens is pleased to propose in combination with high efficiency grading the newly developed Hy-Clean™ filtering tray. It can be installed for grassroots, revamp or catalyst replacement services. 

In hydroprocessing reactors, Hy-Clean™ tray allows to manage all the pressure drop situations when the grading system has already reached its limits:  

• Content of contaminants outside the usual range
• Evolution during cycle of feedstock quality (heavier feedstock, imported feed, feed from storage)  
• Presence of contaminants not foreseen at the design stage

Key advantages:

• Extended Unit Cycle length 
• Avoiding premature unit shutdown due to Delta P 
• No additional pressure drop
