Sustainable biogas - climate and environmental effects of biogas production

, 2021
Biogas er vedvarende energiproduceret ved at fordøje biomasse under anaerobe forhold. Husdyrgødning, spildevand og vådt organisk affald fra industrien og husholdningerne kan anvendes i produktionen, som så også fungerer som affaldsbehandling.Når husdyrgødning leveres til biogasproduktion, reduceres udledningen af drivhusgasser fra husdyr. Processen gør

An Analytical Design Model of a Vacuum Pressure Swing Adsorption Process for Biogas Upgrading

Chemie Ingenieur Technik, EarlyView.
A steady‐state model was developed for a vacuum pressure swing adsorption (VPSA) process comprising adsorption, depressurization, and evacuation steps. The resulting analytical plant design model provides the optimal adsorber height required to achieve a target product purity with maximum bed utilization.

Effect of inoculum to substrate ratio on biogas production from digested goat paunch manure

Arid Zone Journal of Engineering, Technology and Environment, 2014
In this study goat paunch manure (GPM) was anaerobically digested under mesophilic condition to determine its biogas potential. Inoculum to substrate (I/S) ratios of 1.45, 2.2 and 4.3 were digested in biodigesters labeled R15, R10 and R5 respectively to ...

Prospective LCA of E‐Methanol Along the Transformation of Steel Industry

Chemie Ingenieur Technik, EarlyView.
The environmental effects of change in steel production route on e‐methanol production are analyzed as they shift from blast furnace route to direct reduction route. Specific hydrogen demand reduces, as do the avoided CO2 emissions. E‐methanol's overall carbon footprint stays in a narrow range of −1 to −1.1 kg‐CO2‐eq./kg‐methanol.

Beyond hydrogen: Process design of a biogas steam reformer for Fischer–Tropsch synthesis

The Canadian Journal of Chemical Engineering, EarlyView.
The effect of pressure and steam to carbon ratio on carbon conversion. Abstract We present an analysis of a pilot‐scale multi‐tubular biogas steam reforming reactor, part of a sustainable aviation fuel (SAF) development project in Brazil. The novelty of this work is the application of a new, validated power law kinetic model, specifically developed for
