Abstract:
PURPOSE: An apparatus for simultaneous production of synthetic oil and electricity is provided to synthesize synthetic oil by supplying synthetic gas to a Fischer-Tropsch synthesis reactor unit. CONSTITUTION: A steam methane modifier(1) generates a synthetic gas with a H2/CO ratio of 3:1 or more by modifying supplied natural gas. A first and a second heat exchanger(21,22) are installed in a heat exchanger supply pipe(2), to supply high temperature synthetic gas to a pressure-changing absorption separator(3). The pressure-changing absorption separator separates the synthetic gas into a synthetic gas with H2/CO ratio of 2:1, and high purity hydrogen, and supplies the same to a synthetic gas supply pipe and high purity hydrogen supply pipe, respectively. A Fischer-Tropsch synthesis reactor unit generates electricity by using the high purity hydrogen. A methane heat exchange supply pipe(6) has a third heat exchanger(61) to increase the temperature of methane, and supplies the methane.
