Chemical Processing

In chemical processes, vacuum drying is often used to remove solvents or moisture from a solution or a suspension to form a dry solid. Our vacuum pumps are specifically designed to handle low-pressure environments, effectively remove air and moisture from the vacuum chamber, creating the necessary vacuum for drying processes.

Vacuum distillation is a process used to separate liquids by heating them under low pressure. This reduces their boiling points, allowing the separation of components without applying high heat. Vacuum pumps are great for removing non-condensable water and light solvents by providing pressure variations, which helps with further separation.

Filtration is a method used to separate solid particles from liquids or gases by passing the mixture through a filter. In the chemical process industry, this is often done to remove impurities, recover valuable solids, or clarify liquids. Our vacuum pumps are essential to this process, as they create a precise vacuum environment that facilitates quicker liquid passage through the filter. Additionally, the design of our pumps minimizes the risk of contamination during filtration, helping to maintain the purity of the filtrate.

Vacuum systems play a crucial role in the recovery of solvent vapors across various applications, including drying, distillation, compound synthesis, purification, and cleaning. In these processes, solvent vapors are efficiently drawn through the dry vacuum system and condensed at the exhaust, creating a closed-loop system for containment and recovery. Stokes dry vacuum pumping systems are particularly well-suited for this purpose, as they operate without internal sealing liquids, eliminating the risk of contamination.

The evaporation process involves the transition of a liquid into vapor at temperatures below its boiling point. Vacuum pumps are essential in this process because they help lower boiling points. By creating a vacuum environment, these pumps enhance the rate of evaporation, allowing for quicker removal of solvents or moisture. This increased efficiency is crucial for optimizing production processes and preserving the long-term activity of sensitive materials.
