Sulfur is the fifth most common element by mass on Earth. If something comes out of the ground, it probably has sulfur in it.

Our engineering, design, controls, and fabrication staff have designed and built sulfur units for over two decades. Proper design and fabrication of sulfur processing and handling equipment takes unique experience and know-how.

Principal Technology provides expert solutions for sulfur recovery. We specialize in open-art and proprietary unit designs, tailored specialty equipment, and controls for all of the traditional sulfur block process units, including Amine Treating and Regeneration, Sour Water Treatment, Sulfur Recovery, Tail Gas Treating, Thermal Oxidizers, Sulfur Handling and Degassing, and Oxygen Enrichment units.

our work

amine treating and regeneration

Amine Treating and Regeneration

Our knowledge and experience with various types of amine in different applications allow us to select the appropriate amine, strength, and circulation rate to provide optimum equipment design and cost for your application.

The reliable and stable operation of a plant’s Sulfur Plant usually starts with the Amine Unit.   Correctly sized low-pressure Rich Amine Flash Drums, well-designed filtration, and reliable Amine Regenerator controls are just a few of our design standards that help our units operate reliably.

small capacity sulfur

Small Capacity Sulfur Recovery

A change in domestic crude feedstocks and increasingly stringent state and federal environmental regulations have raised the demand for small capacity Sulfur Recovery Units in a broader range of process plants.

Principal Technology specializes in turn-key modular units from under 2 to 50 LTPD, affording us unique experience and capabilities to address specific issues of small capacity sulfur recovery, including Heat Conservation, Temperature Management, and Equipment Design to meet the particular needs of small capacity operations while reducing overall cost.

sour water striping

Sour Water Stripping

Sour water units usually see a little bit of everything that runs through a plant.  Principal Technology has the knowledge and experience to provide the right solution for your application, from direct steam injection to reboiler units with pump-around condensing.  

Correctly sized sour water storage and stripping unit equipment design, Principal Technology can reduce utility usage and optimize capital cost while meeting your plant’s required stripped water composition.
