DEC.SRU™
Solvent Recovery Units, also known as Solvent Recovery Plants, SRP or Solvent Recovery Systems, SRS, are employed in solvent-based manufacturing processes to control air emissions of solvents (VOCs Volatile Organic Compounds and HAPs, Hazardous Air Pollutants from solvent-laden air or vapor) to comply with global, regional and local environmental regulations and directives.
Solvent Recovery Units (DEC.SRU™) are designed to meet the stringent regulatory requirements pertaining to VOC air emissions. Volatile Organic Compounds, emitted during various industrial processes, contribute significantly to air pollution and are subject to strict environmental controls. The DEC.SRU™ acts as a robust solution for industries seeking to minimize their environmental footprint by efficiently capturing and recovering these VOCs.
By incorporating advanced technologies, DEC Solvent Recovery Unit ensures that the released air is within permissible limits, aligning with environmental regulations: this not only helps industries comply with stringent VOC emission standards but also promotes a cleaner and healthier environment for surrounding communities, while saving up to 90% on solvent costs.
DEC is offering several decades of experience in design and installation of the most technically advanced and efficient vapor phase activated carbon solvent recovery systems.
Apart from its environmental advantages, Solvent Recovery Unit (DEC.SRU™) offers compelling economic benefits by enabling the recovery and direct reuse of solvents. Solvents play a vital role in various manufacturing processes, and their efficient use is crucial for cost-effective production. Solvent Recovery Unit (DEC.SRU™) allows for the direct reuse of recovered solvents, significantly reducing the need for new solvent purchases.
The cost savings achieved through solvent recovery contribute to an impressive Return on Investment (ROI): industries adopting Solvent Recovery Unit (DEC.SRU™) can experience a substantial reduction in operational costs related to solvent procurement, subsequently enhancing their overall financial performance.
Solvent Recovery Unit (DEC.SRU™) contributes to the generation of important savings by offering an alternative to the conventional practice of thermal oxidation (DEC.XTO™): rather than incurring expenses associated with purchasing fresh solvents, industries can capitalize on the cost-effective option of reusing recovered solvents. The financial implications of such a sustainable approach extend beyond immediate savings on solvent procurement, positively impacting the overall profitability and competitiveness of manufacturing operations.
Solvent Recovery Unit (DEC.SRU™) • concepts
A Solvent Recovery Unit (SRU | SRP | SRS) consists of a specifically designed DEC.SBC™ static concentrator, coupled with an “in-situ” regeneration process.
A static concentrator employs an DEC.AAS™ • adsorbent to adsorb contaminants (VOCs, solvents) from a gas (SLA, solvent-laden air): selected adsorbent shall be a highly porous material with a large surface area, which makes it an effective adsorbent (typically DEC.ACA™ • activated carbon). The adsorbent is packed into a series of adsorbers, and the gas stream is passed through the adsorbers in sequence. As the stream passes through each adsorber, contaminants are adsorbed onto the adsorbent. Once an adsorber is saturated with contaminants, it is taken offline and regenerated. Regeneration involves both mechanical and thermal energy to be delivered to the adsorbent: these combined energies will drive off the adsorbed contaminants (known as desorption). These contaminants are then driven through a condenser (heat exchanger), for direct condensation and reuse. Once desorption cycle is completed, the adsorbent will be ready for the next adsorption cycle.
