DME FPSO Integrated cooling apparatus for DME FPSO

摘要

The present invention relates to a DME FPSO using a cryogenic cooling system for an air separation unit (10) for producing O ₂ and a DME cryogenic freezer (40) for cooling DME, characterized in that the refrigerant of the air separation unit (10) and the DME cryogenic freezer (40) is configured to perform heat exchange in an expander-type cooling system (60), and DME is cooled in a DME cryogenic freezer (40) with a cryogenic heat amount of the air separation unit (10). Thus, the advantage of an offshore plant such as DME FPSO is maximized by integrating an air separation system for supplying oxygen and a system for cooling the DME to a set low temperature.
