Energy Recovery for Solvent Recovery
DEC.ULP™ ♻️ Ultra-Loop™
Reduce energy costs and emissions with Ultra-Loop™ | DEC.ULP™, the future of Solvent Recovery Units (SRUs).
Industrial VOC emissions pose a significant environmental challenge. Solvent Recovery Units (SRUs) are vital, but outdated designs struggle with energy inefficiency and rising energy costs. Enter DEC.ULP™ | Ultra-Loop™: a revolutionary and transformative process that delivers significantly improved energy recovery, reduced operational costs, and a substantial leap towards a more sustainable industrial future. Moreover, existing SRUs can be retrofitted with DEC.ULP™, enabling a rapid upgrade to state-of-the-art performance, thanks to DEC.ULP™ scalable design.
Outdated Solvent Recovery systems often suffer from high operating costs, particularly due to energy-intensive heating during the AC regeneration phase. These "old" systems can be inefficient and environmentally burdensome.

The Ultra-Loop™ | DEC.ULP™ process represents a cutting-edge, state of the art, modular solution for resource recovery, designed to maximize efficiency and sustainability. By further consolidating heating and gas condensation (in the same AC regeneration phase - process release DEC.THR5™ and DEC.THR7™), DEC.ULP™ recovers thermal energy and achieves substantial energy savings over traditional TSA techniques. This hybrid process (combining the best features of different technologies and processes), through faster AC regeneration times, can also boost per-cycle Solvent Recovery capacity. Heat recovery increases the overall efficiency of the Solvent Recovery process while reduced energy consumption and emissions contributing to a more sustainable and environmentally responsible operation.
improved energy efficiency and faster return on investment
Ultra-Loop™ | DEC.ULP™ process is an advanced technology that improves energy efficiency and accelerate the regeneration of activated carbon beds, reducing overall operating costs. The core principle is to capture and repurpose heat that would otherwise be wasted.
DEC.ULP™ | Ultra-Loop™ • how it works
DEC.ULP™ | Ultra-Loop™ • key benefits
DEC.ULP™ is the "best in class" innovative process allowing for faster AC regeneration cycles, boosting Solvent Recovery capacity and reducing operating costs:
DEC.ULP™ | Ultra-Loop™ • reduced Energy Consumption
The DEC.ULP™ eco-friendly process configuration can deliver up to a remarkable 20 to 40% reduction (depending on the selected configuration matrix) in the heat thermal balance of the Solvent Recovery Units (SRU), translating into substantial energy savings and increased process efficiency. This innovative technology demonstrates DEC continuous pursuit of enhanced energy efficiency in SRU processes, paving the way for sustainable and cost-effective Solvent Recovery solutions.
At the heart of Ultra-Loop™ lies a unique combination of THR™ processes applied activated carbon (AC) and hot nitrogen regeneration DEC.RSG™ TSA process, a revolutionary technique that utilizes the inherent properties of AC to effectively remove solvents from contaminated streams. Unlike conventional steam regenerated SRUs, DEC.RSG™ employs an effective TSA cycle (with hot nitrogen) significantly reducing the energy demand and associated environmental footprint.
DEC.ULP™ | Ultra-Loop™ • harnessing waste heat
DEC.ULP™ is an innovative waste heat process specifically designed for Solvent Recovery applications. This approach drastically reduces the energy consumption, by maximizing the recovery and reuse of the TSA energy: DEC.ULP™ can achieve up to a 40% reduction in the heat thermal balance of the Solvent Recovery system (DEC.SRU™). The recovered heat can be used in other stages of the process, reducing the need for additional energy to reach the required temperature. Reduced energy consumption translates to lower operating costs, including fuel, electricity and water.
DEC.ULP™ | Ultra-Loop™ • streamlining complexity
Unlike conventional TSA regeneration cycles that rely on steam, the RSG™ • TSA inert gas N2 has a simpler and more straightforward approach: this allows for the recovery of solvent mixtures that are either soluble or partially soluble in water or form azeotropes with water.
When paired with DEC.ULP™, the RSG™ • TSA inert gas N2 process offers significant advantages over vacuum-assisted T+VSA systems involving complex and costly systems, contributing to the overall SRU operation expenses. Additionally, vacuum operation can present operational challenges (e.g. steady SLA flowrates and VOC concentrations) and safety concerns. Conversely, DEC.ULP™ eliminates these complexities, lowering capital expenditures and ensuring a more secure and reliable operation.
DEC.ULP™ | Ultra-Loop™ • strategic CAPEX management
Ultra-Loop™ | DEC.ULP™ process offers flexible implementation pathways, available both as an integrated option for new Solvent Recovery Unit (SRU) constructions and as a provision for future integration. This forward-thinking approach allows companies to either maximize efficiency from the outset or strategically plan for future enhancements. By providing the option for later add-on, DEC.ULP™ enables businesses to manage initial capital expenditure while ensuring seamless scalability and long-term operational optimization.
DEC.ULP™ | Ultra-Loop™ • retrofit
The versatility of the Ultra-Loop™ | DEC.ULP™ process extends to its seamless integration with existing Solvent Recovery Units (SRUs): this retrofit capability allows industries to enhance their current infrastructure without the need for complete overhauls. By strategically incorporating DEC.ULP™'s innovative heating and gas condensation technology, businesses can significantly improve energy efficiency, boost Solvent Recovery rates, and reduce operational costs, all while leveraging their existing capital investments.
DEC.ULP™ | Ultra-Loop™ • versatility
Ultra-Loop™ | DEC.ULP™ process is designed for versatility, allowing it to be seamlessly interfaced with complementary systems such as Combined Heat and Power (CHP), Combined Cooling, Heat and Power (CCHP), Thermophotovoltaic (TPV) and Organic Rankine Cycle (ORC) technologies: this integration capability enhances overall energy optimization, enabling industrial facilities to maximize efficiency across multiple energy recovery and generation processes while maintaining a compact and sustainable operational footprint.
DEC.ULP™ | Ultra-Loop™ • a paradigm shift
The introduction of DEC.ULP™ marks a significant advancement in Solvent Recovery technology. By recovering TSA energy and reducing the need for external heating sources, DEC.ULP™ achieves remarkable energy efficiency gains and simplifies the SRU process. This hybrid innovative approach not only reduces operating costs but also contributes to sustainable industrial practices. As industries seek to optimize resource utilization and minimize their environmental footprint, DEC.ULP™ is poised to become the preferred process coupled with SRU Solvent Recovery method for gas phase applications.
The Ultra-Loop™ | DEC.ULP™ process exemplifies DEC’s dedication to pioneering sustainable solutions, achieving energy savings in Solvent Recovery. By leveraging innovative TSA technology, DEC continues to redefine environmental efficiency, setting new standards for industrial sustainability. Lower energy consumption leads to reduced carbon footprint and contributions to climate change mitigation.
