The working process of our solvent recovery plant:
One of the best solvent industrial solvent recovery systems manufacturers and suppliers in Pune, our solvent recovery plant is made with advanced technological innovation, which improves the overall structure and productivity. Here we have listed down the process in detail:
- Collection of Solvent-Laden Air/Stream: This is the first and most important step of our solvent extraction plant, collecting solvent-laden air or liquid from multiple industrial processes such as chemical production, printing, and pharmaceutical manufacturing. We utilize a vapor phase absorption system with carbon beds and zeolites that absorb the solvents from the vapor, resulting in a pure form. The advanced filtration system also helps separate the particles from extraction.
- Pre-Treatment (Condensation): In this process, the collected vapor or heat is transferred into the condensation stage, where the temperature of the solvent-laden air or liquid is lowered to liquefy the solvents. This is beneficial for removing the bulk of the solvent and preparing it for further processing. We employ cryogenic condensation technology in our solvent recovery plant, which cools the liquid with nitrogen and improves the recovery rate for low-volatility solvents.
- Absorption: During this step, the remaining solvents in the air stream are absorbed into a solid material. The process can utilize zeolite-based absorption and solid materials such as carbon or zeolite. Zeolites are more activated than carbon materials, and the new technological pressure swing adsorption (PSA) is particularly effective for continuous absorption under higher pressure.
- Desorption (Regeneration of Adsorbent): This is typically a regeneration process aimed at obtaining more accurate forms of solvents. The solvent is heated or steamed to desorb it from the absorbent. New technologies such as vacuum desorption and microwave regeneration methods help lower the pressure and enable direct heating of the absorbent material, improving energy efficiency.
- Distillation: After the condensation and absorption processes, the entire mixture proceeds to the distillation phase, where the solvents are purified, and impurities are separated. Our advanced distillation processes in solvent recovery systems, such as multi-stage distillation units and vacuum distillation, enhance separation efficiency, allowing for accurate and pure product extraction at lower temperatures.
- Solvent Purification and Drying: Upon completion of the distillation process, the solvent still contains water and other contaminants. Additional separation methods are implemented to eliminate impurities and achieve precise extraction. Our solvent recovery plant employs new separation technologies, such as membrane separation and advanced molecular sieves, functioning as prevaporation and nanofiltration for effective water separation.

Unique Feature and Benefits of Using Our Solvent Recovery System:
As a former solvent recovery plant manufacturers and suppliers in Pune, our plant is made with pure forms of materials such as aluminum, copper and nickel and equipped with new technologies and gives more performance, such as:
- Distillation Technologies: Due to the integration of industrial automation 4.0, we have installed multiple technologies such as Multi-Effect Distillation (MED) and vacuum distillation, which utilize multi-stage distillation for purifying components and reducing waste from unwanted mixtures. Additionally, vacuum distillation lowers the overall temperature or boiling point and employs vacuum technology to minimize thermal degradation.
- Membrane Separation Technologies: This is one of the most critical procedures in our solvent recovery system, enabling the recovery of solvents from materials. The evaporation process aids in the removal of solvents through vaporization, while reverse osmosis (RO) is employed to separate solvents based on molecular size using a semi-permeable membrane.
- Cryogenic Condensation: This feature is beneficial for recovery systems where waste solvent vapors are cooled to very low temperatures using gases such as liquid nitrogen. This method consumes less energy compared to other cooling techniques and is commonly used in various industrial applications, including industrial and specialty chemical production, food and beverage industries, and metal fabrication.
- Environmental Compliance: Our solvent recovery plant operates with lower energy consumption compared to traditional facilities, and the entire process is conducted with reduced emissions while effectively capturing VOCs. The new technological processes also minimize human intervention, as these systems recycle waste materials for other applications.
