APPARATUS FOR PRODUCING NITROGEN EQUIPPED IN A MARINE STRUCTURE AND METHOD FOR PRODUCING NITROGEN USING THE APPARATUS

摘要

A nitrogen producing apparatus equipped in a marine structure and a nitrogen producing method in the marine structure by using the same are provided to utilize the nitrogen producing apparatus in the marine structure having a narrow space by using LNG(Liquefied Natural Gas) as a refrigerant for the nitrogen producing apparatus, by bypassing LNG and to secure the small volume and a simple process. A nitrogen producing apparatus is installed in a floating type marine structure having LNG regasification equipment for compressing LNG contained in a storing tank, by a high pressure pump(13), vaporizing the LNG by the natural gas in a vaporizer(14), and then supplying the vaporized LNG to each place. The nitrogen producing apparatus produces nitrogen to be mixed in the natural gas regasified and supplied to each place. The nitrogen producing apparatus secures cold heat needed to produce nitrogen, by using LNG fed from the storing tank.
