Abstract
A process for the production of synthesis gas for obtaining compounds such as ammonia or methanol, in which hydrocarbons and steam are reacted first in a primary reforming section (11) and then—together with oxygen—in a secondary reforming section (12), thus obtaining CO, CO2, H2 and possibly N2 which are then fed to a carbon monoxide conversion section (13, 14), is distinguished by the fact of reacting hydrocarbons, steam and oxygen in an autothermal reforming section (20) provided in parallel with respect to other reforming sections (11, 12), and feeding the so produced CO, CO2, H2 and possibly N2 to the carbon monoxide conversion section (13, 14).
Claims5
A process for the production of synthesis gas, comprising the steps of:
- feeding a first flow comprising hydrocarbons and a first gas flow comprising steam to a primary reforming section;
- feeding a first gas flow comprising oxygen to a secondary reforming section;
- reacting said hydrocarbons and said steam first in the primary reforming section and then—together with said oxygen—in the secondary reforming section, obtaining a first gas phase comprising CO, CO2 and H2;
- characterized in that it further comprises the steps of:
- feeding a second flow comprising hydrocarbons, a second gas flow comprising steam and a second gas flow comprising oxygen to an autothermal reforming section arranged in parallel with respect to said primary and secondary reforming sections;
- reacting said hydrocarbons, said steam and said oxygen in said autothermal reforming section, obtaining a second gas phase comprising CO, CO2 and H2;
- combining said second gas phase comprising CO, CO2 and H2 with said first gas phase comprising CO, CO2 and H2.
