Thermoelectric refrigeration technique was used to condensate the vapor of the VOCs with high temperature and high concentration. The effects of condensation time,electric power and the temperature of hot face of the thermoelectric module on the condensation process were investigated. Results indicated that the use of thermoelectric refrigeration can quickly condensate the VOCs to the designed temperature within 1.5 min, and the partial pressures of the VOCs in the exit gas became very low. With the increase of the temperature of the hot face of the thermoelectric module, the temperature of exit gas and the required electric power increased.
