At the heart of DEC's industrial Advanced Dehydration Modules (DEC.ADM™) is the innovative DEC.UDS™ (Ultra Dehydration System) technology. This advanced industrial liquid phase solvent dehydration process is engineered to boost efficiency and cut operating costs significantly.

DEC.UDS™ (Ultra Dehydration System) technology is based on molecular sieves (DEC.MZA™), designed to significantly increase the efficiency while reducing the operating costs.

Industrial processes often involve solvents that require precise dehydration to maintain product quality, while optimizing downstream processes (e.g. distillation processes). Traditional dehydration methods can be energy-intensive, lead to solvent loss, and may not achieve the desired purity levels. These limitations directly impact operational costs and overall process efficiency.

how it works • DEC.UDS™

The foundational technology underpinning the exceptional performance of DEC.UDS™ is its reliance on molecular sieves (DEC.MZA™). Molecular sieves are highly porous crystalline materials with a uniform pore size, allowing them to selectively adsorb molecules based on their size and polarity. In the context of dehydration, DEC.MZA™ molecular sieves are specifically engineered to efficiently capture water molecules while allowing the solvent to pass through unimpeded.

key benefits • DEC.UDS™

The integration of DEC.UDS™ with DEC.MZA™ molecular sieve technology delivers tangible benefits in terms of efficiency and cost reduction:


  • Enhanced Dehydration Efficiency: the precise and selective nature of molecular sieve adsorption ensures extremely low residual water content in the treated solvent, leading to improved product quality and process performance;
  • Reduced Energy Consumption: compared to thermal dehydration methods, DEC.UDS™ can significantly reduce energy requirements due to the highly efficient adsorption and regeneration processes;
  • Minimized Solvent Loss: the non-destructive nature of molecular sieve dehydration helps to preserve the integrity of the solvent, minimizing valuable product loss (e.g. through hydrolysis) and improving overall yield;
  • Lower Maintenance Requirements: the robust design of DEC.UDS™ and the durability of DEC.MZA™ molecular sieves contribute to reduced maintenance needs and increased system uptime;
  • Increased Throughput: by providing consistently dry solvents, DEC.UDS™ can optimize downstream processes, potentially leading to increased production capacity.

The DEC.UDS™ Ultra Dehydration System, powered by advanced DEC.MZA™ molecular sieve technology, represents a significant advancement in industrial liquid phase solvent dehydration. By offering unparalleled efficiency, substantial operating cost reductions, and reliable performance, DEC.UDS™ is an indispensable component of modern industrial activated carbon Solvent Recovery Units (DEC.SRU™), enabling businesses to achieve higher quality products, greater operational efficiency, and ultimately, a stronger competitive edge.

FAQs • Frequently Asked Questions

Ultra Dehydration System • DEC.UDS™

What is DEC.UDS™?

DEC.UDS™ (Ultra Dehydration System) is DEC's industrial liquid-phase solvent dehydration technology, based on DEC.MZA™ molecular sieves, that removes residual water from recovered solvents within DEC.ADM™ (Advanced Dehydration Modules).

How does DEC.UDS™ work?

DEC.UDS™ passes the liquid solvent through a bed of DEC.MZA™ molecular sieves, highly porous crystalline material that selectively adsorbs water molecules by size and polarity while letting the solvent pass through unimpeded.

How does DEC.UDS™ fit into a DEC.SRU™ solvent recovery unit?

DEC.UDS™ is a downstream, skid-mounted polishing stage for activated carbon Solvent Recovery Units (DEC.SRU™), delivering the ultra-low residual water content required for high-purity solvent reuse.

What are the main benefits of DEC.UDS™?

DEC.UDS™ delivers enhanced dehydration efficiency, reduced energy consumption compared to thermal methods, minimized solvent loss, lower maintenance requirements, and increased downstream throughput.

Is pricing available for DEC.UDS™, and how do I get a quote?

DEC.UDS™ is part of a custom-engineered, quote-based DEC.ADM™ system, so there is no fixed list price. Each system is sized and priced per project once DEC's engineering team evaluates your process requirements; contact DEC's Technical Sales & Applications engineering team through the contact page to request a quote.
