What is Solvent Recovery?

Solvent Recovery is the technique of recovering valuable materials from waste or by-product solvents produced during the manufacturing process. Solvent recovery helps in reducing waste. One can limit waste creation by using In-process solvent recovery, which is also an alternative to solvent replacement. Similar to end-of-pipe pollution control, it is appealing since it needs minimum modification of current procedures.

A solvent recycling device removes dirt, debris, and oils from old cleaning solvents through distillation. It enables to reuse of the cleaning solvent. There may be a decrease of over 90% in overall chemical waste disposal costs. Generally, there is a 95% reduction in solvent purchase if one uses solvent recovery processes.

A solvent recovery device lowers the expense of new solvent purchases and chemical disposal. One can recover and recycle solvents by using a solvent recovery vacuum. Here we have gathered more information about fuel and solvent recovery vacuum systems used in industries to recover solvents for reuse or recycling.

Advantages of Solvent Recovery:

  • Allowing industries to repurpose recovered chemicals will lower the cost of raw materials and solvents and the shipping and disposal of chemicals.
  • Decreased disposal of solvents and chemicals reduces the hazardous risks.
  • Reclaimed chemicals can enhance the overall production efficiency.

How does Fuel and Solvent Recovery Vacuum Pump Work?

In-process solvent recovery using vacuum technology is an alternative to solvent substitution to cut costs and waste. Economically, using equipment for solvent vapour recovery that includes vacuum pumps and condensate receivers is superior to substitute raw materials.

A complete system design could be necessary for more extensive or complex systems. Since distillation is a common application for solvent recovery systems, the design approach uses the same principles as distillation design. The solvent is often removed from waste fluids by heating, distilling, and collecting it as vapour, which is then cooled back to liquid for reuse.

Solvent Recovery – Typical Actions

  • One needs to determine the fundamental system needs. It includes flow rates, chemicals to be recovered, and other characteristics.
  • Figuring out the essential compounds that need to be separated relative volatility. A mass and energy balance simulation tool is used to represent the physical and chemical characteristics of the compounds you are attempting to separate.
  • Once an appropriate simulation has been conducted, tradeoffs are investigated to create a final optimized version employing key ratios and operational inputs.
  • Complete system design is finished, including P&IDs, automation designs, equipment lists, and other design documents.
  • Our cutting-edge fabrication facility is the on-site location for fabrication and controls engineering. That makes it possible to fabricate systems remotely without interfering with any already running processes or on-site building improvements at your business.
  • Before shipping, all finished solvent recovery systems are thoroughly inspected. They arrive ready for process connections, and installation usually takes less than a week for modular systems. On-site commissioning begins immediately after installation.

4 Process of Solvent Recovery

Vacuum systems for recovering fuel and solvent are widely used in the chemical, pharmaceutical, metal powder, taste and fragrance, and PET solid-state production industries. For instance, the solvent recovery procedure usually goes like this:

  1. Condenser/receiver tank for solvent recovery, liquid ring vacuum system. The intended product is frequently present in a liquid combined with a solvent.
  2. Vacuum and heat are used to evaporate the solvent.
  3. Our systems either drain straight into a liquid ring vacuum pump or
  4. Condense the solvent and store it there.

The solvent storage tank is pumped or emptied of any accumulated solvent. There is frequent use of vacuum systems for solvent recycling. They are used in connection with the following categories of industrial machinery:

  1. Batch reactors
  2. Vacuum dryers
  3. Granulators

To enhance recovery and minimize contamination and environmental problems, Spillrite Vacuums typically use liquid ring vacuum pumps sealed with one of the solvents in the incoming process stream.

Calculating the size of the vacuum pump and comprehending how varied solvent qualities impact a pump’s performance are both challenging aspects of using a solvent-sealed vacuum system. Spillrite Vacuum sizes and designs solvent-sealed process vacuum systems using unique, in-house designed vacuum pump sizing software.

Solvent Recovery Applications

One can use solvent recovery systems in several industrial applications. They include:

  • Refining crude oil
  • Cleanup of petrochemicals
  • Production of pharmaceuticals
  • Manufacturing of hazardous and non-hazardous chemicals
