FLNG is a new type of FPSO device which integrates the function of liquefaction

storage

loading and unloading and outward transport of marine natural gas.With the advancement of deepwater oil and gas development

the research

design and localization of FLNG has become hot in the past decade

and FLNG has also become an important technology to the development of the deepwater natural gas in the South China sea.In this paper

in connection with the development of the deepwater natural gas in the south China sea

we develop and put forward a proposal of liquefaction technology and key device of FLNG topside for South China sea with appropriate capacity of 2 million ton/year which has proprietary intellectual property rights.It contains the new process of twin columns and two circulation of amine solution

the improved DMR liquefaction process particular for FLNG

use aviation derivative gas turbine to drive refrigerant compressor and power generation

the self-developed FLNG aluminum coil-wound heat exchanger(CWHE)is used as the pre-cooling and cryogenic main heat exchanger.It has the advantage of reliability

safety

high efficiency and operability.Two suggestions are put forward in order to advance the Chinese FLNG engineering implementation in the South China Sea:(1)Accelerate the localization design and test of the FLNG aluminum coil-wound heat exchanger(CWHE)

(2)Improve the ability of FLNG engineering practice.
