摘要:
A process for enhancing the operability of hot gas cleanup for the production of synthesis gas in which a stream of methane rich gas is autothermally reformed at a temperature and pressure sufficient to generate a stream of synthesis gas rich in hydrogen and carbon monoxide, the synthesis gas is subjected to condensation and removing the resultant water, and sulfur impurities are removed from the resultant synthesis gas stream.

摘要:
An improved, economical alternative method to supply steam and methane to a steam methane reformer (SMR) is accomplished by a combination of procedures, wherein product gas from a steam hydro-gasification reactor (SHR) is used as the feedstock for the SMR by removing impurities from the product stream from the SHR with a combination of autothermal reforming, condensation removal and gas cleanup procedures that operates substantially at process pressures and at a temperature above the boiling point of water at the process pressure, is located between the SHR and SMR. In another embodiment, a method is provided for controlling the H2/CO syngas ratio obtained from a steam methane reformer (SMR) by adjusting the hydrogen feed and the water content of feedstock into a steam hydro-gasification reactor that supplies the SMR.
摘要:
Systems and methods for processing a methane rich producer gas are provided in which the producer gas is preferably produced via steam-hydrogasification. The product stream from the steam-hydrogasification is then subjected to autothermal reforming, steam is removed after the reforming step via condensation, and sulfur impurities are subsequently eliminated. In most preferred aspects, the process pressure is substantially maintained throughout all steps, typically in a range of 150 psi to 500 psi.
