Sulfuric Acid Regeneration

The challenge as we see it

Many industrial facilities produce a spent sulfuric acid by-product that can be regenerated into a full strength high-quality sulfuric acid. Alkylate is the preferred blending agent for high-quality motor fuel because of its high octane number and low smog creation. Sulfuric acid (H2SO4) or hydrofluoric acid (HF) is used as a catalyst in refinery alkylation units. Once the sulfuric acid reaction occurs to make alkylate, the spent sulfuric acid can be regenerated back to its original high-quality sulfuric acid.  Due to the corrosive nature of the acids used in making alkylate, there are severe safety consequences if mishandled.

Our differentiated value

We know how to run a safe and environmentally-friendly sulfuric acid plant and share our knowledge on the safe handling, use and storage of sulfuric acid and spent sulfuric acid with our customers.

Our Acid Technology Center is staffed with world-class experts in their field who work closely with our environmental, process safety and operational teams to solve operational, maintenance and technical challenges for our customers and operating sites.

  • We have supply chain and logistics experts.
  • We partner with highly-skilled transportation providers to ensure the product gets to you on time and safely.
  • We provide training on the handling and management of sulfuric acid products.

Veolia owns and operates sulfuric acid regeneration plants throughout the United States.

Our solutions for sulfuric acid regeneration

Veolia is a leader in spent sulfuric acid regeneration (SAR) services to the refining and chemical industries.  We work with our customers to determine the beneficial reuse options for handling spent acid.

Customers have the option of transporting spent sulfuric acid to Veolia’s state-of-the-art merchant facilities or we can build, own and operate an onsite SAR facility that is adjacent to the refinery.

Our onsite SAR plants provide a cost-effective, environmentally-sound and flexible alternative to traditional sulfur management systems. These plants not only regenerate the refiner’s spent acid, but also recover part or all of a refiner’s acid gas as sulfuric acid or other sulfur products.

Some of the benefits of this approach include:

  • Cleaner, more effective acid gas and sulfuric acid recovery solutions compared to classic Sulfur Recovery Units
  • Enhanced focus on core refinery operations
  • Improved operational flexibility
  • Potential CAPEX reduction

We can supply a range of sulfuric acid products, varying in strength and quality requirements.
