In case you missed our last installment of “Inside In Situ Thermal Remediation”, TerraTherm’s new informational webinar series, you can find a recorded version here:
The focus of this presentation was to provide an overview of thermal treatment options for LNAPL-contaminated sites, and will cover:
- Thermal remediation progress over the last 10 years,
- Similarities between In Situ Thermal Remediation (ISTR) and thermally enhanced oil recovery,
- LNAPL remediation case studies, and
- A large LNAPL spill case – using the energy in the recovered fuel to power remediation and obtain sustainable clean-up.
TerraTherm uses all three main thermal technologies: Steam Enhanced Extraction, Electrical Resistance-based heating, and In Situ Thermal Desorption, plus combinations of these matched to the subsurface conditions (more than 50 completed thermal field projects). After developing the methods such that very predictable results may be obtained, the next phase has been to optimize the sustainability aspects of these labor and utility-heavy technologies. This has special interest for LNAPL sites with a large oil mass, since these contain considerable energy and may be used effectively to reduce the overall environmental footprint of the soil or groundwater remediation. The basics of these synergies will be presented. For refineries, the new processes may translate into sustainable and rapid restoration, while the waste energy in the spilled product is utilized.
