METHOD FOR PRODUCING SYNTHESIS GAS USING STEAM CATALYTIC REFORMING Russian patent published in 2024 - IPC C01B3/02 F02C6/00 

FIELD: synthetic gas production.

SUBSTANCE: invention relates to a method for the production of synthesis gas using steam catalytic conversion, including the separation of natural gas into two streams, one of which is preheated in a coil and distributed through a manifold to the burner devices of a steam catalytic conversion furnace, and the second is mixed in a gaseous fuel supply pipeline with flow of stripping gas coming from the ammonia synthesis section, after mixing these flows, the resulting stream of combined gas fuel is supplied to a gas turbine unit, the inlet of which is also supplied with air from the first air intake device; as a result of combustion of the combined gas fuel and air, a stream is formed at the outlet of the gas turbine hot flue gases with an oxygen content of about 15 vol.%, which is sent for mixing with the air flow coming from the second air intake device and heated in the coil to 280°C, then the mixed flow is supplied to the burners of the steam catalytic conversion furnace and, burning in them, forms hot flue gases, which, moving from the radiant section of the steam catalytic conversion furnace, enter the convection section, where they give up their heat to the flue gas heat recovery system coils intended for heating steam, raw gas and water, the flue gases that have given off heat are taken by a smoke exhauster and released into the atmosphere, while the gas turbine drives an electric generator to generate electricity at the ammonia production plant.

EFFECT: it is possible to increase energy efficiency and flexibility in the production of ammonia, which uses a tubular furnace for steam catalytic conversion of natural gas to produce partially converted synthesis gas, which then enters the steam-air conversion stage.
