Sentence examples for biogas data from inspiring English sources

Modeling of the generated biogas data was done using the Response Surface Methodology.

In the absence of field biogas data the novel application of the computer modelling software BioWin® was carried out to simulate chemical oxygen demand (COD) removal rates and subsequent biogas yield.

Top Total biogas (no data available on the individual contributions of the fermenter and the post digester).

Data for biogas engineering projects have been reported since the late 1990s by MOA (1996 2004); and the feature of these data series in different regions shows different patterns in comparison with household ones: Some are monotonously changed, while others have obvious fluctuations, thus forecast models should be more diverse according to circumstances.

As described above, according to the experiment data of biogas production and liquid characteristics, the H group was not inhibited in this period, in which biogas production was similar to L and M.

Data on biogas production and quality are summarized in Fig. 1, while Fig. 2 summarizes changes in the pH-values and the volatile fatty acids (VFA) together with the corresponding calculated VFA/TIC-values and the ammonia-N-values.

When using ecoinvent data, preferring biogas over natural gas is mainly a question of having a short-term or long-term perspective and not so much a question of higher or lower uncertainties for one option compared to the other.

This is explained through the fact that biogas options in our data have higher methane emissions, which have a short atmospheric lifetime and therefore a high impact in the short term but a much lower in the long term compared to fossil CO2 emissions (the main problem of fossil fuels).

The analysis accomplished between the experimental data of biogas produced, pH and temperature values supports the conclusions.

It was also concluded that additional experimental data from biogas production using first- and second-generation substrates are required to obtain improved economic evaluations.

We demonstrated earlier that reductant accessibility is a regulating factor in biogas production and presented data supporting the hypothesis that the introduction of H2-producing bacteria into a natural biogas-generating consortium appreciably increases the efficacy of biogas production both in batch fermentations and in scaled-up anaerobic digestion [ 6, 10].
