Durasorb™ HG

Durasorb HG

Durasorb HG is a high capacity, robust mercury adsorbent designed to operate in the harshest conditions

Durasorb HG is a sulfided metal oxide adsorbent installed upstream in the LNG pre-treatment train to protect downstream equipment and materials from mercury contamination.

Durasorb HG has improved capacity and fast kinetics due to the optimal pore distribution, which allows fast diffusion of mercury into the core of the sphere.

Durasorb™ HG

Lab test results show the unmatched material integrity of Durasorb HG.

Durasorb HG is easily removed from the vessel at the end of life due to material robustness. No loss of crush strength or fines generation in the presence of liquid water means no caking, no extreme techniques required for removal.

Water Soaking Test: Durasorb HG was soaked in water at 80°C for 3 weeks, with no loss of crush strength over time.
