Coil-wound heat exchangers are widely applied in natural gas liquefiers, but existing heat transfer coefficient correlations are constrained and inaccurate, which leads to overdimension of heat exchangers.

 Authors developed test installation and measured heat transfer coefficient for boiling in shell-side of hydrocarbon mixture with various composition, mass flux, temperature and pressure.

Correlation based on experimental results was made for existing model for heat transfer coefficient, which considers multicomponent composition.

Recommendations for coil-wound geometry to enhance heat transfer are given.
