Fractional Dehydration Process
DEC.FDP™
At the heart of DEC's industrial Advanced Dehydration Modules (DEC.ADM™) is the innovative DEC.FDP™ (Fractional Dehydration Process) technology. This advanced process is engineered to boost efficiency and cut operating costs significantly. It achieves this through a selective DEC.KDA™ (Kinetic Desorption Algorithm), which is further optimized by DEC.AIP™, Artificial Intelligence (AI) and Machine Learning (ML).
DEC.FDP™ (Fractional Dehydration Process) technology is a core component of activated carbon Solvent Recovery Units (DEC.SRU™), designed to significantly increase the efficiency while reducing the operating costs.

DEC.FDP™ • how it works
The DEC.FDP™ process is integrating DEC's proprietary Kinetic Desorption Algorithm (DEC.KDA™) with advanced selective dehydration technology. Designed for complex process streams containing moisture and mixed volatile organic compounds (VOCs) - including Ketones, this configuration enables high-purity solvent recovery directly from the gas phase.
DEC.FDP™ • Key System Highlights
- Selective Water Removal: using precise thermodynamic controls and kinetic separation via DEC.KDA™, water vapor is isolated and condensed separately from the target organic solvents;
- Enhanced Solvent Purity: by removing water within dedicated condensation stages, the recovered solvents maintain maximum concentration, eliminating or significantly reducing the need for downstream second stage dehydration processes (DEC.UDS™);
- Optimized Energy Consumption: the targeted thermal profile of the FDP™ cycle optimizes energy consumption, lowering overall operational expenditure (OpEx) for the Customer;
- Reduced Operating Costs: lower energy consumption directly translates to decreased operational expenses;
- Seamless Process Integration: designed for full compatibility with existing industrial manufacturing lines, providing reliable air pollution control (APC) alongside resource conservation.

FAQs • Frequently Asked Questions
Fractional Dehydration Process • DEC.FDP™
What is DEC.FDP™?
DEC.FDP™ (Fractional Dehydration Process) is DEC's selective dehydration technology that isolates and condenses water vapor separately from mixed VOC and ketone streams, using the proprietary DEC.KDA™ Kinetic Desorption Algorithm optimized by DEC.AIP™ artificial intelligence and machine learning.
How does DEC.FDP™ fit into DEC.ADM™ and DEC.SRU™?
DEC.FDP™ is one of DEC's Advanced Dehydration Modules (DEC.ADM™) and is a core component of activated carbon Solvent Recovery Units (DEC.SRU™), integrating directly into those systems to boost efficiency and reduce operating costs.
Does DEC.FDP™ reduce the need for a second dehydration stage?
Yes. By removing water within dedicated condensation stages, DEC.FDP™ keeps recovered solvents at maximum concentration, eliminating or significantly reducing the need for downstream second-stage dehydration (DEC.UDS™).
What are the main benefits of DEC.FDP™?
DEC.FDP™ delivers selective water removal, enhanced solvent purity, optimized energy consumption, reduced operating expenditure, and seamless integration with existing manufacturing lines while providing reliable air pollution control.
How can I get a quote for a DEC.FDP™ system?
Since DEC.FDP™ systems are custom-engineered into each customer's DEC.SRU™ solvent recovery unit, DEC's Technical Sales & Applications engineering team reviews your process stream and VOC/HAP emission control requirements before providing a project-specific quote.
