Selection and Design of Vapor and Liquid Treatment Systems

April 23, 2025 | 10:00 AM Pacific / 1:00 PM Eastern

Vapor and liquid extraction and treatment systems are essential components of in situ thermal remediation (ISTR). These maintain pneumatic and hydraulic control during all phases of heating to ensure that the contaminants of concern (COCs) are effectively captured and removed from the treatment zone and unwanted mobilization and spreading are prevented.

Once recovered, the COCs must be removed from the vapor and liquid streams for proper disposal. In this fourth webinar in our series titled “The Nuts and Bolts of Thermal Remediation,” we will look at how vapor and liquid extraction and treatment systems are designed.

Presenter Steffen Griepke will draw on his experience to cover:

• Choosing the right treatment technologies for specific COCs and mass levels.
• Special considerations for treating PFAS and 1,4-dioxane.
• The fundamental components of ISTR treatment systems.
• Selecting appropriate materials for vapor manifolds and treatment equipment.
• The role of the mass and energy balance in sizing equipment and in managing the cooling and heating loads.
• Effective strategies for handling non-aqueous phase liquid (NAPL) recovered from the treatment zone or condensed out in the vapor manifold and equipment.
