Abstract (en)
[origin: EP2147896A1] Process for utilizing synthesis gas heat for the generation of supercritical steam in a low energy ammonia or methanol plant comprising a reforming or partial oxidation stage (1), at least one supercritical steam generator (3) having a shell side and a tube side, at least one superheater (14), at least one back pressure turbine (17), at least one extraction and condensing turbine (23), at least one boiler feedwater pump (7). The synthesized synthesis gas (2) is sent to the shell side of the supercritical steam generator (3), the supercritical steam generator (3) is fed with pressurized feedwater (4), the feedwater flow is adjusted to maintain the steam temperature at the exit of the supercritical steam generator in the range of 375-500 °C (13), the supercritical steam is generated in the supercritical steam generator at a pressure of 225-450 bar, the supercritical steam (13) is further heated in a superheater (14) to a temperature of 500 - 750 °C, and the supercritical steam generated in the superheater is fed to a back pressure turbine (17).
