The Texaco Gasification Process (TGP) employs gasification technology to treat, or remediate, contaminated soil by destroying the hazardous organic compounds in the soil while forming a glassy slag and producing syngas. The Superfund Innovative Technology Evaluation (SITE) Program accepted the TGP into the program and conducted a field test Demonstration at the Texaco Montebello Research Laboratory (MRL) in South El Monte, California in January 1994. Contaminated soil, in slurry form, from Purity Oil Sales, a Superfund site in Fresno, California, was treated in the MRL High-Pressure Solids Gasification Unit II. Slurry was prepared from the soil (after pretreatment size reduction), coal, water, slurry additives and spiking compounds. The paper provides information on the technology description, applicability, and limitations, and on the latest performance data from that demonstration.
