Case Study: Light Cycle Oil (LCO) and Gas Oil Spill
Original Date of Case Study:
Submitted By:
Product: Piranha
Site Location: Refining Facility of major oil company (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.
Contaminants Treated: Gas oil and light cycle oil fuel and oil
Geology: Caliche and Sandy Soil
Starting Levels: TPH levels ranged from 26 to over 1,300 ppm. 13 samples were collected in the treated area. 5 samples from around Tank A and 8 samples from around Tank B in randomly selected points.
Cleanup Standards: per the State of Texas (TCEQ)
TPH (total petroleum hydrocarbons): less than 50 ppm.
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.
