With growing need for natural gas as an energy source, demand for offshore facilities for reception, storage and gasification of natural gas is also growing. At such facilities, the entire process of natural gas gasification and delivery to the distribution network takes place. The floating plant is most often converted from a ship for transport of liquefied natural gas, where gasification system is installed. LNG Croatia is an example of such a converted ship. Maximum volume of the ship is dimensioned so that it should adequately cover natural gas needs of the Republic of Croatia. Gasification of liquefied natural gas at LNG Croatia takes place in an indirect gasification system. In an indirect system, two heat exchangers are used, one a plate heat exchanger, and the other a shell and tube type. Plate heat exchanger is used for heat exchange of sea water and glycol-water mixture. Glycol-water mixture is called the intermediate liquid in this process. Its main function is to transfer heat of seawater onto liquefied natural gas, so that it changes its aggregate state from liquid to gaseous. The exchange of heat between glycol-water mixture and liquefied natural gas takes place in the shell and tube heat exchanger. In this manner, liquefied natural gas is gasified at the Krk LNG terminal.
