Summary

Shell-side thermodynamic calculation of coil-wound LNG heat exchanger is one of the important problems to be solved. Shellside heat transfer models on low-temperature conditions are mentioned on very few occasions. It is a necessity to choose the best thermodynamic calculation correlation on cryogenic working conditions. The existing shell-side single phase heat transfer models were evaluated. Using the shell-side measurement data of coil-wound LNG heat exchanger on low-temperature conditions,this paper got the best shell-side heat transfer model for the pre-cooling stage of natural gas liquefaction process,and optimized this model. In conclusion,Abadzic heat transfer model gets the best accuracy and the strongest applicability,so it is properly selected for the pre-cooling stage of natural gas liquefaction process. The accuracy can be improved about 50% by the use of viscosity correction,the factor of which in the pre-cooling stage should be estimated at 1. 05.
