Abstract: This application relates to an adsorption desalination system using a multi-effect evaporator apparatus. In one aspect, the system includes a multi-effect evaporator apparatus producing high-temperature vapor and low-temperature vapor, a plurality of reaction units including an adsorbent adsorbing or desorbing moisture from the high-temperature vapor and low-temperature vapor and a heat exchange tube transferring heat to the adsorbent. The system may also include a condenser condensing vapor containing moisture desorbed from the adsorbents, and cold-hot water lines selectively supplying chilled water and hot water to the heat exchange tubes. The system may further include vapor lines connecting the multi-effect evaporator apparatus and the reaction units, and the reaction units and the condenser, respectively, valves disposed in the vapor lines, and a valve controller controlling operation of the valves to selectively supply chilled water or hot water supplied to the heat exchange tubes from the cold-hot water lines.

Abstract: Proposed is a ship cogeneration system using waste heat of an LNG engine ship recovered through an economizer. More particularly, proposed is a ship cogeneration system using waste heat of an LNG engine ship recovered through an economizer. The ship cogeneration system is configured to generate electric power by recovering waste heat generated from an LNG engine and providing high-temperature and high-pressure steam discharged from the economizer to an evaporator of an organic Rankine cycle. The ship cogeneration system is capable of removing soot generated on a contact surface between the exhaust gas of the LNG engine and the economizer by using some of the high-temperature and high-pressure steam.

Abstract: Proposed is a complex system of offshore wind power generation, seawater desalination, and water electrolysis. The system may include a wind power generator which generates electric power in such a manner that blades are rotated by wind power. The wind power generator may include a cooler for preventing a overheating phenomenon caused by electric power generation. The system may also include a seawater desalination apparatus which desalinates seawater by using hot water discharged after heat exchange through the cooler. The system may further include a water electrolysis apparatus which receives fresh water produced by the desalination apparatus and a heat source discharged therefrom to use the fresh water and heat source for producing hydrogen. A part of a heat source discharged from the water electrolysis apparatus after the production of hydrogen may be heat-exchanged with the cooler, and heat-exchanged with the heat source discharged from the desalination apparatus.
