Abstract: This paper analyzes the typical structure of the LNG intermediate fluid vaporizer (IFV). It expounds its main heat transfer process and heat transfer calculation method. The paper also introduces the pilot test equipment of IFV and analyzes the pilot test results. The test results show that the overall performance of the IFV meets the design requirements and the actual measurements of design margin agrees with the theoretical values, which indicates that the design and calculation method is correct and reliable. Moreover, the industrial application effects indicate that the heat transfer calculation, engineering design and manufacturing techniques of IFV satisfy the operating requirements of the LNG receiving terminal.
