Research on calculation of relieving capacity of LNG tank pressure relief valve
Based on API and GB specifications,the calculation methods for relieving capacity of LNG storage tank were summarized and compared.The calculation methods of relieving capacity for stor-age tank pressure relief valve in SI units and UCS units were introduced in detail according to API and the manufacturer's handbook,and the calculation formula for the absolute pressure ratio of the discharge coefficient was fitted.The results showed that the calculation results of the fitting formulas were similar to those calculated by the manufacturer.In addition,a certain engineering project was applied to compare the calculation results of the specification,manufacturer handbook and the fitting formula,which have good consistency.It can enhance the engineering designer's further understanding of the relieving capaci-ty of storage tanks and pressure safety valves,and provide calculation guidance.
