Company History

Founded in 1945, Merichem® has a long relationship within the oil and gas industry as well as a long history of innovation. We pioneered the recovery of cresylic acids from heavy FCC spent caustics and in the 70s, invested in our own barges, developed our revolutionary FIBER FILM® extraction process and acquired the John T. Files Technical Center for its research and development initiatives. Acquisitions and steady global growth followed, as we expanded our capabilities to include chemical manufacturing as well as fabrication capabilities for our modules and proprietary equipment. Today, Merichem® continues its innovative success, granting over 1,250 technical licenses to operate various technology offerings and transforming its caustic management services, providing our clients with consistently flexible and reliable service.
