At the PCI plant in Pasadena, TX, sulfuric acid has been produced since 1949. The current sulfuric acid plant was upgraded in 2014. All PCI products are “primary products,” not by-products of other processes. Each product is made to specifications to ensure the highest quality product.

Quality Sulfur-Burned Acid

Using locally-sourced, elemental sulfur in our processes, we know exactly from where our sulfur originates, from refinery to our plant. As a major producer of sulfur-burned acid in the Houston area, we take pride in our quality, virgin-grade acid, produced in two strengths: 93% and 98%. Our on-site laboratory ensures the highest quality product.
