Condenser Unit

The Condenser Unit is a critical component of the Solvent Recovery Module responsible for phase change from vapor to liquid. It receives hot solvent vapors from the distillation or evaporation process and uses cooling media (typically water or air) to remove latent heat, causing condensation. This recovered liquid solvent is then collected for reuse or proper disposal, improving process efficiency and reducing environmental impact. The unit is designed for integration into chemical manufacturing processes where solvent recovery is required. It operates on the principle of heat transfer through conduction and convection. Hot solvent vapors flow through tubes or plates while cooling media circulates on the opposite side, creating a temperature gradient. As vapors lose heat to the cooling media, they reach their dew point and transition to liquid phase. The condensed liquid is then gravity-fed or pumped to a collection tank. The unit is available in configurations using Stainless Steel 316L, Copper, or Aluminum, with material selection depending on the corrosiveness of the solvent and process conditions. Key parameters include a heat exchange area of 10–50 m², design pressure of 1.0–1.6 MPa, design temperature of -20 to 150 °C, cooling water flow rate of 5–30 m³/h, cooling water inlet temperature of 5–32 °C, condensate outlet temperature of 20–40 °C, shell-side pressure drop ≤0.05 MPa, leakage rate ≤0.1% (per ISO 15848), material grade 304/316L (per ASTM A240), weight 500–2000 kg, dimensions 1500×600×800 mm, and insulation thickness 50–100 mm. These values are reference ranges for directory purposes and must be verified for the specific model and application with the legal manufacturer or supplier. The unit is a component, not a standalone system, and requires proper integration with upstream and downstream equipment. Maintenance signals include increased pressure drop, reduced condensation efficiency, or visible leakage, which may indicate fouling, seal failure, or other issues. Failure boundaries include exceeding design pressure or temperature, which can damage seals or cause structural failure. Always consult the manufacturer's documentation for installation, operation, and maintenance guidelines.

The Condenser Unit operates on the principle of heat transfer through conduction and convection.

As vapors lose heat to the cooling media, they reach their dew point and transition to liquid phase. The condensed liquid is then gravity-fed or pumped to a collection tank. The efficiency of condensation depends on the heat exchange area, cooling media flow rate and temperature, and the temperature difference between the vapor and the cooling media. Proper design and operation ensure effective solvent recovery and minimize energy consumption.
