Steam Enhanced Extraction

ISTR Challenges Part 2: Electrical Resistance Heating and Steam Enhanced Extraction

Thermal Conduction Heating (TCH), Electrical Resistance Heating (ERH) and Steam Enhanced Extraction (SEE) are widely used thermal technologies capable of effectively remediating a variety of chemicals in various varying subsurface settings, yet sometimes operations do not perform as planned.  An experienced thermal remediation contractor can help you anticipate and address site-specific challenges during full-scale thermal projects.

Presented by Vice President of Development, John LaChance and Vice President of Technology, Steffen Griepke, ISTR Challenges Part 2 covers some of the common issues that can arise at ERH and SEE sites, and discuss how they should be addressed.  You’ll hear about scenarios involving

  • significantly different soil electrical resistivities than planned
  • slower than expected heat-up
  • stray voltages and currents
  • poor steam quality
  • higher than expected mass removal rates
  • lack of hydraulic control
  • non-uniform steam delivery and heating

Join the discussion for insight to help avoid costly project delays in your next thermal project.

What is Steam Enhanced Extraction (SEE) and How is it Applied?

Although Steam Enhanced Extraction (SEE) may not be the most common thermal remediation technology, it is the go-to approach for heating and treating sites with high permeability and groundwater flux. Did you know it’s also the most cost-effective way to input energy into the subsurface?

In this 30-min webinar, two thermal remediation experts will give you an overview of SEE. You will learn:

  • How SEE works,
  • What geologic conditions it is best suited for,
  • Design considerations to ensure a successful SEE project,
  • SEE sweet spots, and
  • Examples of SEE projects.

VP of Technology, Steffen Griepke and Senior Project Engineer, Nikole Huard, will answer your questions about using SEE to remediate sites.

Williams Air Force Base Steam Enhanced Extraction Project – The Largest Steam Project in the World

Join a webinar that will take you on a journey through the transformative efforts at the former Williams Air Force Base in Mesa, Arizona, a former Liquid Fuels Storage Facility (ST012) Superfund Site, where historic releases of JP-4 jet fuel culminated in an estimated spill of 1 to 11.1 million gallons of contaminants.

The site underwent a comprehensive three-stage remediation approach, commencing with the world’s largest Steam Enhanced Extraction (SEE) project, followed by Enhanced Bioremediation (EBR), and concluding with Monitored Natural Attenuation (MNA). This session will shine a spotlight on the monumental first stage – SEE.

The project’s magnitude brought forth a myriad of challenges, from selecting equipment capable of withstanding extreme conditions and high contaminant loads to evaluating pumping systems able to extract hot steam, contaminants and water from up to 240 ft bgs. Delve into how the team navigated these obstacles and innovatively utilized the recovered LNAPL as a sustainable auxiliary fuel source for the vapor treatment system. The presentation will unveil the outcomes of the SEE phase, emphasizing the ingenious strategies implemented to overcome the challenges during the design and operation at ST012.

Join us for this presentation of the world’s largest steam jet fuel remediation project, and the challenges encountered during design and operation of the SEE system. Whether you’re an environmental aficionado, an academic, or intrigued by groundbreaking sustainable practices, this webinar is a treasure trove of insights.

Dive into the groundbreaking remediation techniques of the “Williams AFB SEE Project,” hosted by industry expert Steffen Griepke, VP of Technology at TerraTherm and Stuart Pearson, Principal Environmental Engineer at WSP.
