Abstract

NATURAL GAS IS CONVERTED WITH STEAM AND OXYGEN IN AN AUTOTHERMALLY OPERATED REACTOR, AND FROM THE REACTOR A RAW SYNTHESIS GAS WITH A TEMPERATURE IN THE RANGE FROM 800 TO 1200°C IS WITHDRAWN. TO THE COOLED, RAW SYNTHESIS GAS A GAS RICH IN H₂ IS ADMIXED. THE SYNTHESIS GAS WITH AN INCREASED H2 CONTENT IS CONVERTED IN A METHANOL SYNTHESIS REACTOR ON A COPPER CATALYST AT A PRESSURE IN THE RANGE FROM 10 TO 150 BAR AND TEMPERATURE FROM 180 TO 350°C. FROM THE SYNTHESIS REACTOR A GAS MIXTURE CONTAINING METHANOL VAPOR IS WITHDRAWN, METHANOL IS CONDENSED OUT, AND A COOLED RESIDUAL GAS IS SEPARATED. THE RESIDUAL GAS IS DIVIDED INTO A FIRST PARTIAL STREAM (RECYCLE GAS) AND A SECOND PARTIAL STREAM (PURGE GAS). THE RECYCLE GAS IS ADMIXED TO THE SYNTHESIS GAS BEFORE THE METHANOL SYNTHESIS REACTOR. THE PURGE GAS CONSISTS OF 30 TO 80 VOL- % H₂, 7 TO 35 VOL -% O2 AND 3 TO 25 VOL -% O. THE HOURLY QUANTITY OF PURGE GAS IS 8 TO 25% (CALCULATED DRY) OF THE HOURLY QUANTITY OF RAW SYNTHESIS GAS. THE PURGE GAS IS CHARGED INTO A SEPARATING MEANS, WHERE THE GAS RICH IN H₂ IS RECOVERED, WHICH IS ADMIXED TO THE RAW SYNTHESIS GAS. THE HOURLY QUANTITY OF CARBON DIOXIDE SUPPLIED TO THE SEPARATING MEANS IN THE PURGE GAS IS 10 TO 50% OF THE HOURLY QUANTITY OF CO₂ IN THE RAW SYNTHESIS GAS.
