As planned, the company restarted regular nitric acid and ammonium nitrate production on a partial basis in June, and it is on track to increase that production during July and August.
However, LSB said its DSN concentrated nitric acid plant is beyond repair and it intends to replace the nitric acid production capacity lost by this event with a new plant.
Before the May 15 event, the DSN concentrated nitric acid plant produced approximately 20% of the nitric acid manufactured at the El Dorado Facility.
The three other nitric acid plants, which produce approximately 80% of the nitric acid at the El Dorado Facility in concentrations from 56% to 63%, sustained less damage and are being brought back on-line. The first of these three nitric acid plants has returned to full production, and the other two should restart later this month and August.
"We are making good progress at our El Dorado Facility,” said LSB’s Board Chairman and CEO Jack Golsen. “Although the nitric acid capacity we lost when the DSN plant was destroyed only accounted for about 20% of our total nitric acid output from this facility, we intend to replace that capacity as soon as feasible."
