| Abstract: |
| Printed circuit heat exchanger with its compact, efficient, reliable characteristics can meet the requirements of the main cryogenic heat exchanger in the offshore floating natural gas liquefaction. In recent years, it has gradually become the first priority of main cryogenic heat exchangers of offshore floating natural gas liquefaction. In this paper, the progress of research and application of printed circuit heat exchanger in recent years, including the basic principle, manufacturing process based on diffusion welding, heat transfer and pressure drop characteristics, and mechanical behaviors, is reviewed; the application status of printed circuit heat exchanger in offshore LNG platform is summarized; and the key technologies that requires to be overcome in future applications in offshore LNG platform is proposed, including thermal design, manufacturing process, detection technology. |
