The company operates primarily in the North American sulfuric acid market, offering regeneration services that recycle spent acid from refineries and producing virgin sulfuric acid for various industrial applications. Its business also includes treatment services for hazardous and non hazardous waste and catalyst activation for hydro processing operations.

Ecovyst Inc. generates revenue mainly through the sale of regenerated sulfuric acid to refineries for alkylate production, virgin sulfuric acid to mining and industrial customers, and fees for waste treatment and catalyst activation services. The company’s products are essential inputs that represent a small portion of its customers’ overall costs but are critical to their processes.
