摘要: A novel intermediate fluid vaporization (IFV) technology for LNG re-gasification process with spiral wounded heat exchanging tubes is proposed. The new IFV combines the advantage of operation at high pressure of shell-tube heat exchangers with the advantage of compact heat exchangers. Thermal analysis on the two processes of forced convection vaporization heat transfer in the spiral wounded tubes and vapor condensation /re-boiling heat transfer of intermediate fluid in shell side shows the feasibility of this promising technology.
