<p>The present invention relates to a control apparatus of an LNG production system. More specifically, according to an embodiment of the present invention, the control apparatus of an LNG production system controls a heat exchanger, which exchanges heat among NG, a light coolant (MRL) supplied in a gas phase from a separator of a coolant supply means, and a heavy coolant (MRH) supplied in a liquid phase from the separator to produce LNG. The control apparatus includes: an LNG thermometer which measures the temperature of LNG discharged from the heat exchanger; an LNG flow-meter which measures a flow volume of LNG discharged from the heat exchanger; and an LNG control unit which receives the temperature of LNG measured by the LNG thermometer and the flow volume measured by the LNG flow-meter, and controls the flow volume of LNG to satisfy a predetermined LNG production amount in the range in which the temperature of LNG does not surpass the predetermined upper limit temperature of LNG.</p> |
