GEISMAR- Plant operators at Williams Olefins said Thursday, a vapor cloud ignited after a rupture of a reboiler on June 13 causing the blast that killed two plant workers.
The plant released the information through an emailed news release and said company experts are reviewing the issues and considering necessary improvements to keep the facility safe in the future.
"The company has been, and remains focused on employees, contract workers and families personally affected," the company reported in its statement.
The company said it continues to rebuild and expand the facility in Ascension Parish.
The company identified three main factors for causing the incident:
- Unexpected presence of liquid hydrocarbons in the reboiler in standby mode
- The introduction of heat into this standby reboiler
- Pressure relief system was isolated from reboiler
A reboiler is a specific type of heat exchanger used in the production process.
A federal report detailing the explosion is not expected to be released until next year.
OSHA and the Chemical Safety Board are also investigating.
There was also another incident at the plant involving a fire that is under investigation. No one was injured.
