Corporate Governance and Audits

Ecovyst regularly and on a scheduled basis, performs external audits of financials, compliance and Health, Safety, Environment and Security (HSES) obligations. Additionally, we conduct ongoing internal audits of our HSES management systems and 20 Ecovyst Principles relating to behavioral safety and operating safety, quality procedures, risk identification, financials and compliance to ensure we are meeting or exceeding top industry and internal standards of excellence.

We audit health, safety, environment and security (HSES) using third-party verification systems and auditors, including Responsible Care® (RC) 14001 with joint ISO 14001 certification and, in some cases ISO 9001 as part of our adherence to the concept of “Plan-Do-Check-Act.” This approach allows us to prioritize resources; execute plans and implement controls; monitor progress and continually improve. We track our internal audit processes across the organization, and we use this data and sharing of Best Practices as part of ongoing enhancement efforts.

The four Committees of our Board of Directors are Health, Safety, Environment and Security (HSES); Audit; Compensation; and Nominating and Corporate Governance. Our Health, Safety, Environment and Security (HSES) Committee (HSES) oversees our performance in these areas as well as our Sustainability efforts.

Enterprise Risk Management

Our rigorous Enterprise Risk Management (“ERM”) process enables our team to evaluate and address operational and compliance risks that we face in our businesses.

Our Chairman, President and CEO has established a multi-disciplinary ERM council that examines and oversees risk reduction measures for strategic, financial, credit market, liquidity, security, property, legal, regulatory, reputational and other risks. Led by our General Counsel and Director of Internal Audit, our ERM Council regularly reports on our ERM efforts to our Board Audit Committee.

Sustainability at Work

As we look to the future, we understand that we, as a specialty catalysts and services company, have a key role to play in creating products that are safe for our employees, our customers and the environment.

“In 2019, our Refining business safely recycled 4.9 million barrels of spent sulfuric acid for refineries. We recovered over 100,000 MW of electricity and generated Sulfuric Acid products used to produce Alkylate, a high-octane gasoline component, as well as many other widely used basic materials. Our 2020 goal is to increase our recycling capabilities to over 5.1 million barrels.”

Kurt Bitting, Chief Executive Officer, Ecovyst

Our Zeolite Catalysts product group produces innovative materials that reduce Nitrogen Oxide (NOx) emissions from diesel engines by a minimum of 80% and reduce sulfur in fuels, helping drive sustainable clean air solutions. For over three decades, we have operated this group through our Zeolyst International Joint Venture.

We are driven by the spirit of Responsible Care® in our efforts to be good stewards of the environment and pledge to keep doing so moving forward.

Ecoservices® Sulfuric Acid Regeneration Driving Green Energy and a Circular Economy

Our Ecoservices® business continues its critical focus on Sustainability by using energy derived from Sulfur and waste streams to fuel its circular sulfuric acid regeneration process. Currently the largest North American recycler of spent sulfuric acid, Ecoservices also transforms Sulfur, a byproduct of refining, into Sulfuric Acid, a critical raw material for the proliferation of low carbon technologies.

“In 2020, we recycled over 4.1 million barrels of spent sulfuric acid, contributing to the circular economy, and in 2021, we are on pace to recycle 4.3 million barrels,” said Kurt Bitting, Chief Executive Officer, Ecovyst. He continued, “Our sulfuric acid is also used beyond typical refining applications, and its potential is significant. It is additionally used for various industrial and agricultural uses like fertilizers, batteries, steel, paper, wastewater processing, and pharmaceuticals. Because of this, we will continue to explore ways to increase our recycling capabilities year over year relative to our increases in production. The sustainable aspects of our processes are critically important as we assess and continue to try to reduce our environmental footprint.”

There are approximately 35 million tonnes of sulfuric acid produced in the United States every year, and sulfuric acid is currently the most widely produced and used industrial-based chemical in the United States. “Because of this,” Bitting said, “Ecoservices has focused on its spent sulfuric acid recycling efforts, recovering Sulfur in waste fuels, and reducing other raw material consumption. We also beneficially recapture the energy from the waste fuels to run our processes —avoiding landfill or deep well disposal of waste fuels.”

Sulfuric Acid Regeneration Process

Sulfuric acid becomes spent acid once it is utilized in the refinery alkylation process. Spent sulfuric acid is not usable due to hydrocarbon contamination. The regeneration process decomposes the spent acid into a gaseous sulfur dioxide, where it is then converted back into fresh Sulfuric Acid.

This diagram illustrates the process of regenerating the spent acid into fresh acid. At Ecoservices, over 99% of the regenerated sulfuric acid goes back to the refineries while avoiding landfills or deep well disposal of waste fuels.

Creating Carbon-Free Energy

Ecoservices recovers the waste heat generated from the recycling and sulfur incineration process. That waste heat produces steam which is captured and then converted into truly renewable electricity by our turbine generators. The electricity generated powers the Ecoservices plants or is exported to the local grid. Bitting continued, “Through the steam recovery to electricity process, we can produce 100% of our total electricity demand, the equivalent of powering more than 13,000 residences.”

By capturing the heat in our production process, Ecoservices reduces its impact to the grid, and in some cases, we even sell excess renewable power back to the grid. According to Bitting, “Our sulfuric acid plants are sources of carbon-free energy because we reuse the heat produced by our process to create renewable energy. This results in reduced consumption of traditional power derived from non-renewable sources.”
