Acid Plants

Providing acid plant linings since 1954.

AcidPlant_StaticStaticPicAcid plant linings are inherently challenging due to the corrosive nature of the operations, equipment size and geometry, complex connections, as well as the important temperature and mechanical issues involved. Optimizing performance requires an understanding of the corrosive effects on the materials (both steel and refractory), the thermal profiles through the lining, and the mechanical stability of the construction.

Thorpe is one of the few refractory/acid masonry contractors with the in-house capability to design and install reliable acid plant linings. We have our own experienced engineering specialists and draftsmen to prepare detailed construction drawings for each project. Many of our design concepts and brick construction details are routinely replicated in the industry through various OEM, licensor and owner specifications. In addition to our engineering capabilities, we maintain a large resource of highly skilled bricklayers, craftsmen and field laborers experienced in acid plant and other severe service lining applications.

THORPE has been involved in acid plant linings since 1954. We began with maintenance work and secured our first new acid plant project in 1960. Based upon our unique capabilities, we have expanded our work in acid plants across North America and selected international markets.

Typical Equipment for Acid Plants:

  • Sulfur furnaces
  • Outlet ducts & jug valves
  • Waste heat boiler vestibules & tubesheets
  • Acid towers
  • Pump tanks
  • Converters
  • Acid pads
  • Ductwork


In this unprecedented time, Thorpe wants to express its dedication to maintaining a safe and clean workplace for our employees, and consistent service for our customers. We must all take action and do our part to stop the spread of COVID-19. To effectively combat this, it’s imperative we unite with our communities and implement procedures that prioritize those around us. 

Thorpe understands the situation is quickly changing, and there is no way to predict what the upcoming weeks or months may look like. We can, however, ensure our continual evaluation of COVID-19 and the alteration of preventative measures as needed. In the end, our goal is to protect our staff and continue to provide services to our customers. For more information, please contact us at (713) 644-1247.
