PURPOSE:To obtain the titled reactor capable of reducing the driving energy of a circulating gas compressor by separating the inlet part of the upstream reactor and the intermediate part between the upstream reactor and the downstream reactor, and supplying the unreacted gas. CONSTITUTION:The amt. of an inlet gas from a circulating gas compressor 5 is separated, and a part of the gas is supplied to an upstream reactor 1. Meanwhile, since the pressure drop of the upstream reactor 1 is high and that of a downstream reactor 2 is low, the amt. of gas to be supplied to the upstream reactor 1 with high pressure drop can be reduced to reduce the power load of the compressor. The reduced amt. of gas can be compressed by the compres sor 5 by P2-P1 corresponding to the pressure difference (pressure drop) DELTArho@@@@@@@@@$!0!0!!'@@@P=P7-P10 (including the pressure drop of a heater 7). Consequently, the driv ing energy necessary for compressing the reduced amt. of gas from P2 to P3 can be saved. |
