Thermal Conduction Heating

ERH and TCH – How to Choose Your Thermal Remediation Technology (and Why)

It’s one of the most commonly asked questions when considering thermal remediation, and in this webinar one of the industry’s leading experts will answer it. Join TerraTherm, a Cascade Company’s Vice President John LaChance as he introduces the basic operational theory and concepts for both technologies. He’ll discuss their application to a set of typical site conditions (e.g., low and high permeability zones in unconsolidated and bedrock formations) and contaminants (e.g., CVOCs), and highlight typical design approaches, assumptions, and the pros and cons of each.

John will share real-life examples of full-scale projects involving electric resistance heating (ERH) and thermal conductive heating (TCH), including detailed breakdowns and comparisons of costs. He’ll also touch on ETDSPTM, a form of ERH that employs active injection and extraction of water. If you have burning questions about how ERH and TCH stack up, this is your chance to get them answered.

What You Need to Know About Thermal Remediation for MGP Sites

When a manufactured gas plant (MGP) site is identified for treatment, the typical remediation approach can be expensive and involve hazards for crews and the community. Any time you excavate contaminated soil and transport it for treatment or disposal, you are introducing potential safety and liability issues. Luckily, in situ thermal remediation (ISTR) is often a safe and cost-competitive alternative.

Join this webinar where our Vice President of Development, John LaChance discusses:

  • Primary ISTR technologies, their applicability, and primary removal mechanisms at MGP sites
  • Key design considerations for varying conditions and remediation goals
  • A case study of an MGP site remediated with ISTR, including:
    • Analysis and discussion on the potential role of in situ smoldering in the removal of creosote/coal tar
  • Insights into projects with unique goals, such as
    • Volatilization of low boiling point compounds
    • In situ immobilization of high boiling point compounds, including heavier range TPH and PAHs.
