Solvent recovery systems are widely used in recycling and waste reduction in the packaging industry. To distil the liquid and remove the solvent from the water, a solvent recovery system uses a heating part and a condensation component. A vacuum unit can be used in solvent recovery systems, allowing the device to run at temperatures below the boiling point of the solvent. Alaqua Inc is a supplier of processing equipment as well as a service provider for all kinds of processing equipment. A distillation procedure is used to recycle solvents that involve the following steps:
- On a batch or continuous basis, a distillation vessel conducts waste solvent solution.
- By conductive thermal transfer, a heated jacket injects heat into the waste solvent.
- The vessel may be worked under a vacuum, lowering the solvent’s boiling point.
- The surplus fluid transforms from a liquid to a vapour as it exceeds its boiling point.
- A condenser with both a condensing and a sub-cooling portion collects the sterile solvent vapour. The solution is converted back to a liquid in the condenser and cooled to room temperature.
- The pollutants do not go into a vapour phase and instead remain in the drain port to be discharged.
Benefits of Solvent Recovery Systems
Some of the major benefits of Solvent Recovery Systems are as follows:
- Allowing producers to reuse recovered chemicals reduces raw material and solvent costs, as well as chemical transportation and storage costs.
- Since fewer solvents and additives are disposed of, there are fewer EPA monitoring standards and risks.
- Continued production quality with the use of reclaimed chemicals, which are just as available and efficient as fresh chemicals once they’ve been restored.
Solvent Recovery at Pharmaceutical and Chemical Production Plants
When assessing a pharmaceutical, chemical, petrochemical, or medical device manufacturing facility’s overall performance and profitability, the recovery and reuse of solvents used in processing processes is a critical factor. Organic solvent recovery and reuse have two advantages: it eliminates waste and lowers chemical prices. One of the most popular techniques used in a solvent recovery application is distillation.
The concentration/recovery of residual medicinal substance from the column discharge stream comes second to the recovery of solvents with distillation technology. The traditional approach for facilitating higher recovery rates of the medicinal product is to use evaporation technology after the column.
How Solvents are Recycled and recovered?
Contaminated solvents or mixtures of chemical compounds are heated using heat transfer media (thermal oil, hot water, steam) and brought to a boil using AlaquaInc Environmental’s solvent recycling equipment. The gases that originate from the distillation process are then liquefied and cooled in the cooler by condensation.
Thermal decomposition can occur during the distillation of critical chemical materials. The gentle method of vacuum distillation, which is done at low pressure, is used to avoid this, as well as to minimise energy demand (and thereby lower running costs) (vacuum).
The boiling point of the liquids to be isolated is lowered as a result of the vacuum, as is the likelihood of foaming, and the components evaporate at a much lower temperature than at standard pressure.
