LSB Industries said its El Dorado chemical facility in Arkansas suffered significant damage to the DSN concentrated nitric acid plant and surrounding equipment when a reactor exploded Tuesday morning.

There were no injuries to employees or anyone in the El Dorado community, the company said, adding that it believes there was no environmental release.

LSB is investigating the cause of the event and the extent of the damages, it said.

LSB said it does not have an estimate on the extent of the damages or the repair time. However, the El Dorado facility is out of operation at the present time due to the damage.

It is unknown how long the facility will be out of production.

The El Dorado complex produces and sells about 470,000 tpy of nitrogen-based products, including nitric acid in concentrations up to 98%, sulfuric acid, ammonium nitrate solution, and both high and low-density ammonium nitrate prills.
