基于TANKS模型的储罐VOCs排放量核算

VOCs Emission Accounting of Tanks Based on TANKS Model

为了掌握集输过程中储罐挥发性有机物的排放量,采用美国环保署EPA提出的TANKS计算模型,对小型储罐的排放量进行核算。结果表明:储罐静置排放量占比13%,工作排放量占比87%。分析不同参数的计算结果,发现地区温度越高,风速越大,太阳能总辐射越大,则排放量越大;储罐体积和年周转量分别是影响储罐静置排放量和工作排放量的主要因素。提出了降低储罐温度、优化储罐类型的减排对策。

In order to grasp the volatile organic compounds (VOCs) emissions from storage tanks during gathering and transportation, the TANKS calculation model proposed by EPA was used to calculate the VOCs emissions from small storage tanks. The results show that the static discharge of storage tank accounts for 13% and the working discharge accounts for 87%. Analyzing the calculation results of different parameters, it is found that the higher the temperature, the higher the wind speed and the greater the total solar radiation in the area, the larger the discharge. The tank volume and annual turnover are the main factors affecting the static discharge and working discharge of the tank, respectively. The Countermeasures of reducing the temperature of storage tanks and optimizing the types of storage tanks are put forward.
