American Plant Food (APF), Galena Park, Texas, is eyeing the construction of a $225 million, 500,000 st/y ammonium sulfate plant at Cornerstone Chemical Co.’s 800-acre Cornerstone Energy Park in Waggaman, La.
APF has already held an open house for local residents, but has yet to apply for permits. It does not expect a final decision on the project until 2023.
If the green light is given, construction would start in early 2024, with production possible by mid-2025.
The plant would be able to source ammonia and sulfuric acid from Incitec Pivot Ltd.’s ammonia plant and Cornerstone, respectively, with the later producing sulfuric acid along with other chemicals. The plant would have ready access to barge, rail, and truck transport.
APF is also exploring a technology that would allow it to extract ammonium sulfate from wastewater already produced at the site. The extracted product could represent as much as 13% of the 500,000 st/y capacity.
