About the Technology

Fluidized Bed Concentrator


The Fluidized Bed Concentrator (FBC) is advantageously used in industrial applications with a very high volume of process air exhaust and low inlet emissions concentration where traditional oxidizers require significant amounts of natural gas to sustain combustion and electricity to move the exhaust air.


The FBC operates via three main operations:  1) Adsorption, where the emissions are captured with activated carbon;  2) Desorption, where the emissions are heated and released to concentrate the emissions; and 3) Condensation to convert the pollutants to valuable products or Oxidation to efficiently destroy them in concentrated form.


The FBC's efficient adsorption, concentration, and treatment systems significantly reduce energy consumption, GHG emissions, and maintenance costs.

Bead Activated Carbon Adsorbs Emissions

Bead Activated Carbon Efficiently Adsorbs Organics (i.e. Terpenes) from Exhaust Air:

  • High-fill (adsorption) capacity

  • Small Particle, <1mm diameter

  • High flowability

  • High purity, low dust

  • High Strength, high wear resistance

  • Narrow particle size distribution

Problem:  The problem with emissions control devices is that they oxidize or burn the emissions.  This uses a tremendous amount of energy, creates greenhouse gas emissions, and is very expensive to operate!

Solution:  The alternative patent pending technology uses activated carbon to very efficiently adsorb and recover those same emissions.  Technology has three main equipment components:  

  1. Adsorber:  Captures emissions by moving process air through trays filled with bead activated carbon.

  2. Desorber:  Releases the emissions in a concentrated gas phase by heating the bead activated carbon. 

  3. Condenser or Oxidizer:  Treats the concentrated gas phase by either recovering or destroying the organics.

Benefits:  Reduced Energy Usage, Operational costs, and Greenhouse Gas Emissions. 

Benefits:  Revenue generation from transforming what would have been pollutants into valuable byproducts.

Benefits:  It’s good for industry and it’s good for our air!

FBC Benefits: 

  • Operating temperature reduction of over 1000°F in Adsorber vs oxidizer eliminates or reduces total fuel consumption.

  • Differential pressure reduction of 5-15 inches of water across Adsorber due to fluidized rather than static media reduces electricity consumption to move exhaust air.

  • Reduced weight and smaller footprint expands installation site options including rooftop mounting.

Human Machine Interface (HMI) and Programmable Logic Controller (PLC) System

  • Onsight or offsite access to data

  • Instrumentation and control systems enable analysis, measurement, and control of FBC process variables including temperature, pressure, flow, and level sensors.

  • Operations can be monitored onsight and offsite enabling centralized monitoring and optimization.

  • Powerful data historian analysis and reporting software is available to put near real-time and historical production details in the hands of operators, engineers, operations managers, and centralized monitoring personnel.

Thermal Oxidation Option 

  • Efficient Thermal Oxidation in Concentrated Stream

The Fluidized Bed Concentrator (FBC) Thermal Oxidation system is an option to FBC Recovery where the value of the collected organics is low.   


The FBC Oxidation system concentrates the emissions by up to 5,000 to 1, then controls them via oxidation to efficiently destroy them in concentrated form.


Whether using FBC Recovery or Oxidation, the FBC's efficient adsorption, concentration, and treatment systems significantly reduce energy consumption, GHG emissions, and maintenance costs.
