Sulfuric Acid Plant

Sulfuric Acid Plant

Boilers for Waste Heat Recovery Systems are critical to the cost efficient operation of sulfuric acid plants. Optimus knows and understands how the Boiler must integrate with the Plant's sulfur burner and utilizes specific design features developed for acid plant operating conditions.

Economizers and superheaters for sulfuric acid plants have relatively unique requirements due primarily to the relatively high gas-side pressure and the potentially caustic environment. Superheaters may also operate at high temperatures which can present additional challenges when coupled with the casing's high design pressure. Often these superheaters must utilize stainless steel casing materials at temperatures that provide a very low allowable stress and make thermal expansion a design concern.


Optimus has been designing and manufacturing units for sulfuric acid plants since 1993 and has the necessary experience not only to design them, but to fabricate them with the highest standards of quality and workmanship. Plant operators want and depend on reliable equipment and Optimus/Chanute strives to provide the best in the industry. Because Chanute constantly fabricates tubular boiler equipment for the power and petrochemical industries, our ASME-certified pressure part welders are held to a higher standard of performance, and that workmanship goes into all of our products because we don't know any other way.

Chanute has unique manufacturing capabilities that the Optimus engineers take full advantage of when designing sulfuric acid plant economizers and superheaters. Often this allows the Optimus units to be configured for higher heat transfer efficiencies which results in a reduced surface area requirement and, consequently, a lower-priced product.

Chanute utilizes its on-site capabilities to fin and bend the tubes, machine and fabricate the headers, drill the tubesheets, cut and prep all casing materials, and perform all of the pressure part and casing welds. This gives Optimus/Chanute more control of the manufacturing sequence and schedule which has helped us achieve a remarkable record of on-time delivery performance.
