  7. Abstract:
  8. In petrochemical, Process condensate is mixtures of dissolved gasses and water. Process condensate striper tower is a physical separation equipment where dissolved gasses remove from water by saturated steam. The Process condensate feed is introduced at the top of the column and the steam input is located at the bottom. When the process condensate enters the stripper tower, it comes down the tower also when the steam enters the tower, it goes up, because there is packing portion in the stripper tower and two streams are countercurrent, as result contact between steam and process condensate, a lot of dissolved gases vapors and exits with steam from top of tower. After leaving the tower, the vapor with so much saturated steam distribute into the atmosphere, which corrosion caused by outlet vapors collision with other equipment and this is one of the industries major problems in addition to wasting a lot of energy. Hence it is extremely essential to find a solution to condense the outlet vapors. In the current study, the process condensate enters with flow rate of 24,269 kg/hr, temperature of 64◦C and pressure of 1.5 barg from top of the process condensate stripper and saturated steam enters with flow rate of 7,500 kg/hr, temperature of 168◦C and pressure of 7.5 barg from the bottom of it and vapor exits from tower with flow rate of 8000 kg/hr. Since the heat pipes are a two-phase heat transfer device with very high effective thermal conductivity, therefore, this study is trying to review the performance of these components to condense the outlet vapors analytically and experimentally
