Abstract
An operation method of a synthesis gas reformer of a GTL (gas to liquids) plant is provided with: setting an operation condition of the synthesis gas reformer; determining control target values of a flow rate of the light hydrocarbon gas, the steam, and the CO2, and an amount of heat needed for the synthesis gas reformer; controlling operation load of the synthesis gas reformer; setting a furnace efficiency of the synthesis gas reformer; calculating a combustion load of a burner of the synthesis gas reformer; calculating a lower heating value of the fuel gas based on a composition measurement of the fuel gas of the burner; determining a control target value of the pressure of the fuel gas; calculating a deviation between the control target value of the pressure of the fuel gas and a measured value of the pressure of the fuel gas; and controlling the temperature of the synthesis gas at the outlet of the synthesis gas reformer by adjusting a pressure control valve provided at an inlet of the burner to compensate for the deviation.
