LNG The hydrate based hybrid cold energy storage method of LNG waste cold energy with water treatment method

摘要

The present invention relates to a hybrid seawater treatment method using liquefied natural gas (LNG) cold energy. The hybrid seawater treatment method according to the present invention is a technique of mixing a gas hydrate water treatment and reverse osmosis method using the LNG cold energy. An amount of energy consumed in a conventional seawater treatment method by using the waste cold energy and impurity and salt removal efficiency can be increased. Moreover, a natural gas hydrate generated as a water treatment result can be used as a solid fuel and can provide cold energy by heat exchange through dissociation.
