Through integrated process steps such as adsorption and condensation, solvents are recovered efficiently and prepared for reuse, lowering raw material consumption and overall operating costs. Depending on the required purity levels, our distillation equipment can be designed for continuous or batch operation, as well as vacuum, atmospheric, or pressure.

How Liquid Distillation Works ------------------------------- 01 Distillation Tower In a distillation tower, a liquid mixture is heated. The more volatile components evaporate and rise to the top of the column, while water, as a less volatile component, remains primarily in the liquid phase and collects at the bottom. 02 Rectification Tower A rectification tower is an advanced distillation column. By returning a portion of the condensed vapor back into the column, repeated evaporation and condensation takes place on the bottoms or packing of the column. This significantly improves separation efficiency and enables the recovery of high-purity products. 03 Removal of Solvent Residues When aqueous streams cannot be discharged directly into the sewer system or a water treatment plant, our steam or air stripping towers remove residual solvents prior to discharge. 01/03 Typical Applications for Liquid Distillation ---------------------------------------------- Envanio designs and manufactures distillation systems for extractive and azeotropic distillation, tailored to separate and purify solvent mixtures for your facility’s production processes. Because solvents can be reliably recovered and purified for reuse, our distillation systems are used for a wide range of applications. ###### Recovery, Separation, and Purification of Aqueous and Solvent Streams from Activated Carbon Solvent Recovery Systems ###### Chemical and Petrochemical Processes ###### Pharmaceutical Manufacturing, Including Ethanol Recovery and Purification ###### Semiconductor and Electronics Manufacturing ###### Membrane Production ###### Soil Vapor Extraction and Groundwater Remediation ###### Industrial Degreasing ###### Foam Production ###### Rubber-Coated Fabric Production ###### Production of Biofuels ###### Steam Stripping of Wastewater ###### Dehydration and Purification of Condensed Coating Solvent for Reuse in Lithium-Ion Battery Production ###### Purification of Extracted Natural Oils Under Vacuum ###### Waste Solvent Cleanup of Munitions Manufacture ###### Paper, Film and Foil Coating ###### Publication and Packaging Gravure Printing ![](https://www.envanio.com/fileadmin/_processed_/e/9/csm_20DB60_1_b6c6d5fb6a.webp) 360° Service for Your Air Pollution Control System ---------------------------------------------------- Take advantage of our 360° support for air pollution control systems from Envanio or third-party manufacturers.

By using internal ceramic heat exchange media, the system traps and recycles its own heat, making the entire purification process incredibly energy efficient.

By using electric heating elements instead of gas-fired burners, the system avoids combustion-related byproducts and significantly reduces NOₓ emissions. The result is a cleaner, more sustainable solution for industrial air pollution control.

The system is also well suited for processes where particulate matter and aerosols are generated. An integrated metallic shell-and-tube heat exchanger enables efficient primary heat recovery.

The system is particularly well-suited when heavily contaminated exhaust streams must be treated reliably with high removal efficiencies, and when complex heat recovery systems are not economically feasible.

For cost-effective air pollution control, adsorption is recommended first to concentrate large exhaust airflows with low pollutant loads. The concentrated exhaust air is then routed to downstream recuperative or regenerative thermal oxidation for highly energy-efficient destruction.

In our regenerative systems, both the adsorbent and solvents are recovered for reuse, while in non-regenerative systems, the spent activated carbon is safely disposed of or replaced along with the captured pollutants.

Rigid, high-temperature ceramic filter elements enable the simultaneous removal of particulate dust, heavy metals, sulfur oxides (SOx), and nitrogen oxides (NOx) from process exhaust in a single compact system.

During the regenerative or direct-fired thermal oxidation of halogenated hydrocarbons or sulfur compounds, substances such as hydrogen halides or SOx are generated, which must be scrubbed from the exhaust air in a downstream wet scrubber.
