Start-up procedure for catalytic steam reforming of hydrocarbons

Abstract

Abstract A PROCESS FOR CATALYTIC STEAM REFORMING OF HYDROCARBONS TO PRODUCE HYDROGEN, CARBN MONOXIDE AND CARBON DIOXIDE FROM STEAM AND A GASEOUS HYDROCABON MIXTURE IN A SYSTEM INCLUDING AN INLET REACTOR-HEATER, CATALYSTFILLED TUBES, A HYDROGEN PRODUCT COMPRESSOR, AND A VALVED CONDUIT BETWEEN THE DISCHARGE SIDE OF THE HYDROGEN COMPRESSOR AND THE INLET TO THE REACTOR-HEATER IS STARTED UP BY INTRODUCING AN INERT GAS INTO THE SYSTEM, CIRCULATING SAID INERT GAS THROUGH THE SYSTEM WITH THE HYDROGEN PRODUCT COMPRESSOR BY PASSING IT BACK TO SAID REACTORHEATER, HEATING THE CATALYST-FILLED TUBES TO A TEMPERATURE ABOVE THE DEW POINT OF STEAM WHILE CIRCULATING INERT GAS, INTRODUCING STEAM AND HYDROCARBONS INTO THE SYSTEM, STOPPING THE INERT GAS CIRCULATION BY CLOSING THE VALVE IN THE CONDUIT AND REMOVING HYDROGEN PRODUCT FROM THE SYSTEM WITH THE COMPRESSOR.
