High Degree Hydrogen Production Plant From Biogas , Smr Hydrogen Plant
Ally Hi-Tech is engaged in the gas purification and hydrogen solutions to everywhere required.
Ally develops a hydrogen solution form the biogas which is generated from the digestor. It could benefit the owner who requires the hydrogen, such as the sorbitol production, paper mill plant, sewage treatment, etc..
Process Schematic
Process Description
A pretreatment system consists of compression and desulphurization (i.e. sulfur removal) and decarbonization ( i.e. CO2 removal), which is used to recover the methane in the biogas. A primary desulphurization unit is applied to remove the sulfur. Then, a set of the compressor (s) is employed to boost the biogas to a pressure which is desirable for the downstream decarbonization unit. Before the biogas enters into the decarbonization unit, a secondary desulphurization unit is used to further reduce the sulfur.
The decarbonized gas, called as BIOMETHANE, enters a reforming system, where the biomethane converts into syngas that is composed of hydrogen (H2) and carbon dioxide (CO2) and carbon monoxide (CO) and methane (CH4) and etc..
A PSA unit is deployed to separate hydrogen from syngas. The off-gas of the PSA is recovered as the fuel for the reforming system, as the off-gas entrains significant methane.
