<p>The present invention relates to a liquefied gas treatment system comprising: a first evaporation gas supply line to connect a liquefied gas storage tank, and a demand place; one or more evaporation gas compressors arranged on the first evaporation gas supply line, compressing evaporation gas in a plurality of stages; a vaporizer to vaporize liquefied gas received from the liquefied gas storage tank; a pump to supply the liquefied gas of the liquefied gas storage tank to the vaporizer by pressing the liquefied gas; a second evaporation gas supply line to connect the vaporizer and the demand place; a gas-liquid separator arranged on the second evaporation gas supply line, separating the evaporation gas vaporized by the vaporizer into gas and liquid; and a control part to vary a discharge pressure of the pump by detecting a pressure variation of the gas-liquid separator. According to the present invention, the liquefied gas treatment system returns the liquefied gas not vaporized to the liquefied gas storage tank without an additional liquid pressing unit by vaporizing the liquefied gas while applying a higher pressure than an internal pressure of the liquefied gas storage tank to the liquefied gas. Thus, the present invention obtains maximum space in a ship, and reduces installation costs by omitting the liquid pressing unit. Also, the present invention returns the liquefied gas not vaporized to the liquefied gas storage tank without the additional pressing unit by transferring the liquefied gas to the vaporizer after pressing the liquefied gas to have a higher pressure than the internal pressure of the liquefied gas storage tank using the pump; thereby reducing costs and obtaining space for the ship.</p> |
