  • WATER GAS SHIFT UNIT STEAM SUPERHEATER
    Publication number: 20240294380
    Abstract: A method and system for converting a syngas stream to a shifted syngas stream in a shift reactor comprising a first mode of operation and a second mode of operation. The first mode of operation uses heat from the shifted syngas stream to superheat steam in a heat exchanger. The second mode of operation uses the same heat exchanger to heat a partially shifted syngas stream while the shift reactor is heating up to a normal operating temperature.
