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.

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