在 LNG接收站的设计建造过程中,BOG (boil-off gas)生成量计算的准确性将直接影响到项目建设的设备投资和日常操作的稳定性。为了提高BOG生成量计算的准确性,以某实际项目为例,在传统 BOG计算方法的基础上引入计算机模拟软件———Aspen Hysys,选择Peng-Robinson状态方程对整个接收站的工艺流程进行模拟计算,得到BOG生成量最大工况的BOG量,通过与传统静态设计计算结果进行比较分析,发现了传统静态设计计算方法存在的不足,结果说明了使用 Hysys模拟计算接收站 BOG生成量更能准确反映 LNG接收站的实际情况,适合于 LNG接收站项目在初步设计和详细设计阶段的工艺计算,而传统静态设计计算可用于项目建设初期可行性研究阶段的粗略工艺计算。

In the design and construction of the LNG receiving terminal,the accuracy of BOG (boil-off gas)generation calculation will directly affect the equipment investment and the stability of daily operation.In order to improve the accuracy of BOG generation calculation,taking a proj ect for example, based on the traditional method of BOG calculation,introduced the computer simulation software———Aspen Hysys,selected the Peng-Robinson equation of state,simulated the receiving terminal process, obtained the maximum amount of BOG generation.Through comparison with traditional static design calculation,finding the shortage of traditional static design calculation, the results show that the simulated calculation of BOG generation by Hysys is more accurately reflect the actual situation of LNG receiving station.This method is suitable for the preliminary design and detailed design stage of the LNG terminal,traditional static design calculation can be used to roughly calculate for the feasibility study stage of the LNG terminal.
