On the controllability of a singular nonregular methaniser system. [PDF]
Sci Rep, 2023 AbstractThe control and command of singular systems of non-regular type pose very complex problems for automation engineers. The classic concepts of controllability are not applicable because of the non-regularity of the response of such systems whose internal states are no longer controllable in the temporal or frequency plane. New concepts are rather

The role of biomass gasification and methanisation in the decarbonisation strategies [PDF]
Energy, 2020 Abstract The study explores future development of biomass uses across different climate policy scenarios and under different assumptions of biomass supply availability and technology performances. Broad bioenergy technology portfolios and generations provide flexibility to allocate bioenergy to supply a specific final energy mix and to remove carbon ...

Metaproteomics of cellulose methanisation under thermophilic conditions reveals a surprisingly high proteolytic activity. [PDF]
ISME J, 2014 AbstractCellulose is the most abundant biopolymer on Earth. Optimising energy recovery from this renewable but recalcitrant material is a key issue. The metaproteome expressed by thermophilic communities during cellulose anaerobic digestion was investigated in microcosms. By multiplying the analytical replicates (65 protein fractions analysed by MS/MS)

Odour Measurements at Different Methanisation Sites
Chemical Engineering Transactions, 2018 The number of methanisation production sites increase in Europe. However, the installation of a new site sometimes creates problems with the neighborhood of the sites. The main concern is odours.

Metagenomic analysis of a desulphurisation system used to treat biogas from vinasse methanisation
Bioresource Technology, 2016 We investigated the response of microbial community to changes in H2S loading rate in a microaerated desulphurisation system treating biogas from vinasse methanisation. H2S removal efficiency was high, and both COD and DO seemed to be important parameters to biomass activity.

DAUMEN-Energy “Design for Augmented Methanisation” a contribution to sustainable biomethanation
Water Practice and Technology, 2011 The competition for cultivable acreage between energy and food crops increases in Germany. One part of the problem are the currently installed biogas plants for energy crops, which use mainly the fruit parts of the plants. To mitigate this problem, cellulose may well be used as a main substrate.

Water Science and Technology, 2005 The objective of the study presented here was to investigate the performance of an enhanced two-step anaerobic process for the treatment of WWTP sludge. This process was developed to answer the urgent need currently faced by WWTP operators to reduce the production of biosolids, for which disposal pathways are facing increasing difficulties.

METHANISATION IN AGRICULTURE: ECONOMIC, ENVIRONMENTAL, SOCIAL BENEFITS AND INTERNATIONAL EXAMPLES [PDF]
Scientific Papers Series : Management, Economic Engineering in Agriculture and Rural DevelopmentMethanisation is the process of anaerobic digestion of organic materials, including animal manure and plant residues, resulting in the production of biogas. In agriculture, methanisation provides sustainable waste management solutions, reduces the carbon

A fast extremum-seeking approach for the methanisation of organic waste in an anaerobic bioreactor
IFAC-PapersOnLine, 2019 Abstract We consider the AM2 mechanistic mathematical model of an anaerobic bioreactor, where the controlled input is the dilution rate and the measured output is the methane outflow rate. We show that a control strategy based on switching between two dilution rates is able to bring the trajectories close to the optimal steady-state where the output ...
