Sulfur Plant Services

Turn-down and Long Term Capacity Reduction


Principal Technology's team of engineers and designers have accumulated decades of experience designing, building, and supporting the entire Sulfur Block operations for midstream and downstream processors and refiners as well as supporting new technologies to address sulfur treating in the renewable energy market for bio-diesel, landfill gas, and bio-digestion processes.

From upstream treating processes including Amine Contactors, Amine Regeneration, and Sour Water Strippers to treating hydrogen sulfide bearing vent streams, small and "micro" capacity modified-Claus sulfur recovery units, and large multi-train stick-build traditional SRUs. Our portfolio includes everything from scavenger-based scrubbers and traditional modified-Claus and Tail Gas Units to specialized processes including selective oxidization, sub-dewpoint - Cold Bed Adsorption (CBA) units, sulfur Degassing, storage-handling, and solidification.

PTI's team can support your sulfur operations from Treatment to Truck.

    The availability of low-sulfur feedstocks have created a relatively new challenge for many producers. Sustained reliable operation at reduced sulfur rates can be as challenging as debottlenecking. Our portfolio includes a significant number SRUs built to accommodate broad operating ranges. Achieving 10:1 turndown or sustained operation well below “Nameplate” capacity requires more than just re-ranging your instruments and changing the trim in your control valves. Design strategies for sulfur condensers, disengaging plenums, temperature management, and catalyst bed performance are just a few of the unique turndown challenges PTI has solved.
