Abstract:

 In view of the increase in internal pressure and respiratory loss of oil and gas storage tanks under high temperature, the cooling effect of radi-cool coating applied to the surface of absorption tower kettle of petrochemical storage tank was studied and an experiment was carried out in the plant of Ningbo Zhongjin Petrochemical Co., LTD. The results showed that the radi-cool coating takes advantage of high solar reflectivity, high emissivity and low thermal conductivity index to achieve self-cooling. While the surface of the oil and gas storage tank was sprayed with radi-cool paint, the tank wall temperature dropped by 15℃, effectively reducing the internal pressure of the tank and reducing the respiratory loss.
