A new use for the Tempest is the processing of contaminated soils in the oil and gas industry. Oil andGas collection facility soil covers are historically contaminated with saltwater and oil. Trials conducted in Oklahoma have shown that the salt and oil can be removed from the gravel and soil in the Tempest. The salt and oil are collected at the air discharge of the Tempest system and can be treated further with other processes. The soil and gravel can then be reused on the site eliminating the need for disposal of a petroleum contaminated material.
