Incitec Pivot Ltd.’s (IPL) explosives business Dyno Nobel reported Sept. 5 that a front end engineering design (FEED) study is underway for a carbon capture facility at the Waggaman, La., ammonia plant site that will be capable of processing up to 950,000 mt of CO2 to transport via a pipeline to a permanent geological sequestration site. The move is part of the company’s plans to produce de-carbonized ammonia from the Waggaman plant.
In addition, IPL said it has completed a selection process and has established Memoranda of Understanding (MOU’s) with several short-listed parties to work through options to transport and sequester CO2 from Waggaman.
IPL said it is able to leverage the fact that the plant already produces a high concentration CO2 stream, which “makes it much more economic to process than many other industries’ CO2 streams.”
“We basically only need to compress and dry the gas then send to pipeline,” said IPL Managing Director & CEO Jean Johns.
A new or repurposed gas pipeline will be used to transport the CO2 to the Class VI Well.
Subject to the successful completion of the FEED Study, construction of the carbon capture unit at Waggaman is expected to begin in 2023 and be completed by the end of 2025.
IPL told shareholders at an Investor Day event on Sept. 6 that Waggaman has been producing above its 800,000 mt/y ammonia capacity since the production restart on April 19 (GM April. 22, p. 1).
The company has a target to be Net Zero by 2050, or sooner. Emissions from the Waggaman plant represent 45% of Dyno Nobel’s greenhouse gas emissions, and this project alone is expected to reduce emissions by some 30% against the 2020 baseline, or about 800,000 mt/y of CO2e, IPL said.
