- The explosion originated in the propylene fractionator area of the plant.
- The piping, heat exchangers and reboilers in the area just adjacent to the propylene fractionator have been seriously damaged and will likely need to be replaced.
- Sections of the electrical cable trays in the elevated portions of a pipe rack adjacent to the propylene fractionator tower sustained enough damage such that significant amounts of the electrical power cable and control wiring in the plant will need to be replaced.
- An approximately 50-foot section of the plant pipe rack containing portions of the plant steam system, pipeline ethane feed vaporization systems, and fuel-gas conditioning equipment sustained damage that will require the replacement of support structures and significant amounts of piping.
