TREATMENT SYSTEM OF LIQUEFIED GAS

摘要

In accordance with an embodiment of the present invention, a treatment system of a liquefied gas comprises: a fuel supply line connecting a liquefied gas storage tank to a demander having a pressure measurement sensor installed therein; a pump arranged on a fuel supply line, and to pressurize fuel discharged from the liquefied gas storage tank; a heat exchanger arranged on the fuel supply line between the pump and the demander, and to heat fuel discharged from the pump; a first collection line arranged on a front end of the heat exchanger on the fuel supply line to collect fuel from the fuel supply line; a second collection line arranged on a rear end of the heat exchanger on the fuel supply line to collect the fuel from the fuel supply line; a buffer tank arranged on the first collection line or the second collection line to store fuel; and a collection supply line connected from the buffer tank to the fuel supply line to supply the fuel collected to the buffer, to the fuel supply line, wherein the fuel is collected through the first collection line or the second collection line when pressure of the fuel is sensed at a certain pressure or more by the pressure measurement sensor. In accordance with the present invention, in the treatment system of the liquefied gas in accordance with a pressure condition or a temperature of a liquid or a gaseous fuel collected from the fuel supply line and stored in the bugger tank; the fuel is supplied to the liquefied gas storage tank, a high pressure pump, and the heat exchanger or the demander, thereby preventing an overload of the demander and the fuel effectively distributed and used at the same time.
