SweetTreat™ Solid Adsorbent System

The SweetTreat™ Solid Adsorbent System is an all-inclusive sulfur removal service available worldwide. This first-of-its-kind service features vessels in a lead/lag configuration, filled with proprietary high capacity Brimsorb™ adsorbent.

The System provides a one-stop solution for H2S removal. Through this service, GTC VORRO leases standard systems and performs spent adsorbent change outs. Clients are charged an all-inclusive price based on pounds of H2S removed.


Standard System

The SweetTreat™ Standard System consists of vessels and a lead-lag piping skid. The entire system is NACE compliant for H2S service, and vessels are ASME Section VIII Division 1.

The system design focuses on operability and automation; it is a perfect solution for well head gathering stations or gas processing facilities.

Process Overview

Sour gas is sent through a bed of Brimsorb™. The H2S within the sour gas then reacts with the adsorbent, leaving a sweet gas stream that exits the bed. A typical system includes two beds of Brimsorb™, arranged in a lead-lag configuration, that allows for reliable performance and no down time during change-out. Water is produced as a byproduct that must be drained on a routine basis.
