A multiple optimized separator combined system, a use method for same, and a design method therefor. The separator combined system has a high-temperature, high-pressure separator, a medium-temperature, high-pressure separator, a room-temperature, high-pressure separator, a low-pressure, high-temperature, a low-pressure, medium-temperature separator, and a low-pressure, room-temperature separator. Three different temperatures, namely high temperature, medium temperature, and low temperature and two different pressures, namely high pressure and low pressure, are permutated to form a six-separator combined system, which forms graded temperatures and pressures and individually separate different gaseous-phase products and liquid-phase products. This achieves with respect to separation of a gaseous phase the goal of reducing the operating pressure for downstream equipment while ensuring the purity of recycled hydrogen and the goal with respect to the separation of a liquid phase the goal of S and N removal. |
