Light Cycle Oil Spill around storage tanks.
Site description and location - Refining facility in South Texas
The facility had a spill in the areas surrounding two tanks (A and B), the spill contained light cycle oil (LCO) and gas oil.Treatment Method - in situ The product was applied around Tank B, and in an open area between Tanks A and B. During the treatment free gas oil was found in the area between the tanks. As a result, treatment around Tank A was temporarily suspended in order to discuss and review treatment options. Some of the area around Tank B was not accessible due to maintenance. The decision was made to come back after the maintenance work was finished and to complete the treatment of Tanks A and B. Further treatment involved an additional application around Tank A, and in the areas under the pipe chase to the south of Tanks A and B. Once again, free gas oil was noted during the treatment phase.
Oppenheimer products used:
Five months after the start of the project samples were collected and analyzed. A visual inspection of the entire treatment area was also conducted. No free hydrocarbons were noted in any of the areas surrounding either Tank A or Tank B. While there continues to be detectable concentrations of TPH in the soil, none of the applicable Tier 1 ranges for aromatic and aliphatic hydrocarbons were exceeded.
This met the initial criteria set by the project manager and The State of Texas (TCEQ). The project was deemed to have been successfully completed, and no further treatment of the soil was recommended.
Actual Time Frame – 180 days.
Other Cases Studies
These case studies are only intended to represent a cross section of sites where our family of Oppenheimer products have been used. It is to demonstrate the diverse range of contaminants that can be successfully and effectively bioremediated by our products and applications.
