News June 14, 2016 - Veolia North America has signed an agreement to take over Chemours’ Sulfur Products division. This division is a specialist in the recovery of sulfuric acid and gases of the refining process, which are regenerated in clean acid and steam used in wide range of industrial activities. As a tuck-in to Veolia North America’s Industrial Business, Chemours Sulfur Products division is an excellent complement to Veolia’s existing business, and will reinforce its existing recovery and regeneration capabilities and technologies.  Sulfuric acid is one of the most important compounds made by the chemical industry and is used to manufacture hundreds of compounds needed by almost every industry. Natural gas and oil contain sulfur compounds, both organic and hydrogen sulfide, both of which must be removed before they are used as fuels or chemical feedstock.  Through the takeover of Chemour’s Sulfur Products assets for $325 million, Veolia complements its asset base in the regeneration business, and thus the circular economy. This operation includes the following facilities providing regeneration services and sulfur products: 

- Three Sulfuric Acid Recovery units located on refinery sites in Delaware, New Jersey and Texas.

- A merchant Sulfuric Acid Recovery and sulfur product facility in Burnside, Louisiana.

- Four sulfur-based acid production facilities located in the Mid-Atlantic and East Coast.

Veolia will also be able to rely on the inherent technical expertise relating to sulfur through Chemours’ Acid Technology Center, which boasts 18 engineers who exclusively support the Sulfur Products division.  This take-over provides Veolia with a highly differentiated services offering to allow it to move up the value chain with existing refinery customers, along with an opportunity to cross-sell its existing offerings to a new customer base. It also presents growth opportunities within the refinery services sector, and it positions Veolia to capture future demand for clean gasoline related products.  The Sulfur Products assets, with approximately $262 million in revenue in 2015, employs 250 employees at 7 sites across North America. Parties anticipate closing the transaction within the second half of 2016, subject to customary closing conditions and regulatory approvals.

September 8, 2010 - Gas leak at DuPont plant closes Ohio park, officials say no danger to people in area.  Fire officials say a gas leak at a DuPont plant just outside Cincinnati has caused an evacuation at a county park and golf course.  Miami Township Fire Chief Steve Ober said Wednesday that monitors show the leak of a gas containing oleum was contained to the DuPont property. He says there is no danger to people in the area. He says officials believe little gas was released.  Shawnee Lookout Park and its golf course were evacuated at about 2 p.m. as a precaution.  Ober says oleum is a fuming sulfuric acid and that the company is handling cleanup.  He says no injuries were reported and all non-essential DuPont employees were sent home.


June 25, 2003 - U.S. Environmental Protection Agency Region 5 has cited DuPont Corp. for alleged violations of federal and state clean-air regulations at the company’s Fort Hill sulfuric acid plant, 11215 Brower Road, North Bend, Ohio.  EPA alleges DuPont modified its facility, causing an increase in sulfur dioxide emissions, without meeting federal new source performance standards for sulfuric acid plants or getting a permit to prevent significant deterioration of air quality. Before existing air-pollutant sources can be modified in areas that comply with all national outdoor air-quality standards, companies must get permits that restrict their emissions.  Other alleged violations include failure to use best available technology to control sulfur dioxide emissions, failure to give permitting authorities all relevant information and failure to get installation and operating permits.  These are preliminary findings of violations. To resolve them, EPA may issue a compliance order, assess an administrative penalty or bring suit against the company. DuPont has 30 days from receipt of the notice to request a meeting with EPA to discuss the allegations and how to resolve them.  “EPA’s mission is to protect public health and the environment,” said Region 5 Administrator Thomas V. Skinner. “We will take whatever steps are needed to ensure compliance with the Clean Air Act.”  Exposure to sulfur dioxide can impair breathing, aggravate existing respiratory diseases like bronchitis and reduce the ability of the lungs to clear foreign particles. Sulfur dioxide can also cause acid rain. Children, the elderly and people with existing heart and lung conditions are the most sensitive.
