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.
