Traditional adsorption-desorption units still face various issues in complex operating conditions, primarily including incomplete desorption, low concentration ratios, and unstable discharge points. To address these issues and leverage our company's strengths, we have developed a thermal-assisted vacuum desorption technology.
The heat-assisted vacuum desorption technology combines thermal desorption with vacuum desorption, leveraging the individual advantages of both. It overcomes the issue of concentration and condensation in low-boiling point substances, significantly increasing the concentration factor to over 5,000 times. The desorption gas concentration can reach above 95% and is easy to condense. Specifically, dichloromethane (boiling point 39.5°C) can maintain stable operation at a system standard with only a coolant of 5°C. Additionally, this process solves the problem of incomplete desorption in high-boiling point compounds, raising the applicable boiling point of the adsorption-desorption process to over 250°C, addressing the industry challenge of high-boiling point substances deactivating the adsorbents.
This system achieves one-step compliance for exhaust gas with an average concentration below 50,000 mg/m³, with the exhaust outlet’s concentration stabilized at below 10 mg/m³. Components with boiling points below 250°C, such as halogenated hydrocarbons, alkanes, alcohols, aromatics, esters, organic amines, and organic acids, are all applicable to this technology.
Technical Features:
1) High processing efficiency;
2) High desorption efficiency; desorption efficiency can reach over 95%.
3) High concentration ratio; the concentration of the condensed gas can reach above 95% (mass concentration).
4) Fast desorption rate; the desorption and cooling processes can be completed within 120 minutes.
5) No wastewater produced; no steam introduced, no wastewater generated.
6) No risk of spontaneous combustion or explosion; high desorption vacuum, the system does not have the conditions for combustion or explosion.
Application Fields:
1) High-Concentration Breathing Exhaust from Storage Area
2) Reactor exhaust gas discharge
3) Vacuum Pump Exhaust
4) Non-condensable gas in the condenser
5) Printing and lamination high concentration exhaust gases
