Context

Low Temperature Thermal Desorption of TPH contaminated soil from various gas stations at a fixed facility in Baltimore (MD) and Adelanto (CA). CONOCO PHILLIPS owns and operates a large quantity of gas stations in the United States. In accordance with their general environmental policies, as well as State regulations, those gas stations need to be cleaned-up and put in accordance with current legislation. Therefore, CONOCO PHILLIPS has remediated their gas stations, where the TPH contaminated soil was sent for thermal treatment to the Baltimore (MD) and Adelanto (CA) facilities, owned and operated by Deep Green / Haemers Technologies.

Equipment

Contaminated soils were processed by a counter flow, direct fired LTDU (Low Temperature Desorption Unit) with nominal capacity of 70 tons (US) per hour in Adelanto and 80 tons (US) per hour in Baltimore. The equipment train included a prescreener, belt scale conveyor, rotary dryer, fabric filter baghouse, thermal oxidizer, soil moisturizer, and radial stacker. Natural Gas was used as process fuel in Baltimore, and an additional triple heat-exchanger in Adelanto.

Treatment Target

The soil to be treated contained TPH concentrations up to 15,000 ppm. All soils were cleaned down to a-less than 50 ppm TPH. Air emissions were in accordance with the local air permit conditions.

This project was designed and executed by the current Haemers Technologies team, when they worked within the legal entity L&C SA (formerly Deep Green SA), which belongs to the Haemers Technologies group.
