MEAREG MG-CR VOC Condensation Recovery Unit

Product Overview

The MEAREG MG-CR is a VOC Condensation Recovery Unit. It condenses high-concentration gaseous VOCs into a liquid state for recovery, separating them from the mixed gas. At a certain temperature, the higher the original concentration of VOCs, the higher the condensation recovery rate. It can be used alone or as a pre-treatment before other processes to reduce the load on subsequent adsorption processes while recovering organics.

Working Principle

• Vapor Pressure Difference: Utilizes the different saturated vapor pressures of substances at different temperatures.
• Temperature Selection:Lowers the system temperature to condense gaseous VOCs. Depending on the VOC composition, the temperature can be selected within the range of 0 to -120°C.
• Condensation: The temperature drop causes the vapor pressure to reach a supersaturated state, gradually condensing into a liquid.

Key Features

1. No Safety Distance Requirement:Compared to combustion processes like RCO/RTO, the condensation recovery process can be designed for overall explosion-proofing.
2. Suitable for Complex Conditions:Ideal for high-concentration, mixed exhaust, flammable, explosive, or corrosive conditions where adsorption or combustion cannot be used.
3. Stable Treatment Effect: No need to replace adsorbent materials, and no hazardous waste disposal costs.
4. Modular & Fully Automatic: No manual intervention required, small footprint, unaffected by site terrain. Can be put into use immediately after power and pipeline connection. Temperature range is adjustable from -120°C to 0°C.
5. Low Investment Cost:Low initial investment, with costs recovered in 1 to 2 years.
