    摘要: A methanation section for producing substitute natural gas (SNG) by reacting a fresh syngas, the methanation section comprising adiabatic reactors connected in series, with heat removal and reacted gas-recirculation, wherein the fresh syngas is fed in parallel to said adiabatic reactors. In a preferred embodiment the reacted gas is recirculated to the first reactor and further dilution of the fresh gas at the inlet of the first and second reactor is achieved by steam addition.

    摘要: A process for producing ammonia synthesis gas from a hydrocarbon-containing feedstock, with steps of primary reforming, secondary reforming with an oxidant stream, and further treatment of the synthesis gas including shift, removal of carbon dioxide and methanation, wherein the synthesis gas delivered by secondary reforming is subject to a medium-temperature shift (MTS) at a temperature between 200 and 350° C., and primary reforming is operated with a steam-to-carbon ratio lower than 2. A corresponding method for revamping an ammonia plant is disclosed, where an existing HTS reactor is modified to operate at medium temperature, or replaced with a new MTS reactor, and the steam-to-carbon ratio in the primary reformer is lowered to a value in the range 1-5−2, thus reducing inert steam in the flow rate trough the equipments of the front-end.

    摘要: A process for producing substitute natural gas (SNG) comprising the steps of reacting a fresh syngas (11) into a methanation section (10) comprising adiabatic reactors (101-104) connected in series, with heat removal and reacted gas-recirculation, wherein the fresh syngas is fed in parallel to said adiabatic reactors. In a preferred embodiment the reacted gas is recirculated to the first reactor (101) and further dilution of the fresh gas at the inlet of the first and second reactor is achieved by steam addition.
