摘要
针对高温环境下油气储罐内压增大、呼吸损耗加剧等问题,研究了一种辐射制冷涂料应用于石化储罐吸收塔塔釜表面后的降温效果。在宁波中金石化有限公司厂区内进行了试验。试验表明:辐射制冷涂料能够利用高太阳反射率,高发射率和较低的导热指数,实现自主降温。在油气储罐表面喷涂辐射制冷涂料后,罐壁温度可下降15℃,将有效降低储罐内部压力,减少呼吸损耗。
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.
