Business Overview

Operating as TDC, our Sulfur Services business is a leading emissions reduction partner to the refining industry. We design, engineer, construct, and operate facilities to treat, process, and re-purpose sour gas streams. Our proprietary closed-loop technology helps reduce emissions at our host refineries while simultaneously creating a critical bulk chemical product that we then market to copper mining, pulp, and paper and other industrial customers.

We are a leading producer of sodium hydrosulfide (NaHS) and marketer of caustic soda (NaOH).
