Abstract: Based on the analysis of the current situation of VOCs emissions in the oil tank farm and combining with the total VOCs emissions reduction target required in the national “14th Five-Year Plan”, the VOCs emissions of the storage tank under the conditions of different storage temperature, different storage height and different turnover are calculated by using the formula method. It is proposed that through taking accurate control measures such as increasing the removal rate of oil and gas recovery device, reducing the temperature of oil stored in the oil tanks, increasing the storage height of the tanks, reducing the turnover of oil tanks by feeding while discharging, strictly implementing equipment leakage detection and repair (LDAR) work, and reducing the number of inaccessible sealing points, the VOCs emissions in the oil tank area can be reduced effectively, thereby achieving emission reduction target.
