Veolia North America plans to make "a meaningful investment" for a project that will increase capacity at its Burnside sulfur regeneration facility in Darrow by 15 percent.

The amount of the debottlenecking project investment was not immediately available.

"The debottlenecking project at Burnside will address some of the equipment, process and system design issues that limit our current capacity — and improve our overall market position and reliability," said Veolia North America President and Chief Executive Officer William J. "Bill" DiCroce.

The Burnside plant converts spent sulfuric acid into fresh, commercial quality sulfuric acid, and produces a number of sulfur-based products. Refineries use sulfuric acid as the catalyst in their alkylation units to produce high-octane gasoline.

"This is an important step forward in growing our Regeneration Services capabilities," DoCroce said. 

Refiners today are pushing the current acid regeneration circuit to nearly 100 percent capacity because of spiking demand for alkylate. Veolia expects to complete the project during the plant’s fall 2018 maintenance turnaround.

In addition to the expansion, the Burnside facility will celebrate is celebrating its 50th anniversary.
