Dynamic biogas upgrading based on the Sabatier process: Thermodynamic and dynamic process simulation

Upgrading biogas produced at dairy farms into renewable natural gas by methanation

“…The drivers are sized based on the brake horsepower, plus as additional 50% to account for leaks, errors, and reserve capacity. To obtain an estimate of the methanation reactor size and cost, the reactor specifications from the literature are adopted . The decanter is sized to hold an equivalent of 10 times the flow rate of gas passing through it per a rule of thumb.…”

Feasibility study on combining anaerobic digestion and biomass gasification to increase the production of biomethane

“…For the chemical Sabatier reaction, since it is reversible, it is hard to reach very high CH 4 purity (>90 mol%) [14]. For the biological Sabatier reaction, Luo et al [17] has tested to use enriched hydrogenotrophic methanogens.…”

“…Chemically, it can be achieved by using ruthenium and nickel based catalyst [13]. This technology has been applied on an industrial scale in ammonia plants for the removal of carbon oxides from feed gases [14], and in Synthetic natural gas (SNG) plants for methane production from syngas [15]. As the Sabatier reaction is exothermic, it does not consume much energy, resulting in a high energy efficiency and low cost, consequently.…”

The Potential of Biogas; the Solution to Energy Storage

“…[28][29][30][31] However,s of ar only few demonstration plants have been reported. Much ongoing research is investigating the possibility of implementing catalytic methanation at biogasp lants.…”
