Methane content (biogas composition) measurements from three batch bottles, organized in a “wide” format.
data("vol")
A data frame with 5 observations on the following 4 variables:
time.d
elapsed time of mass measurements (from bottle setup) in days, a numeric vector.
D
biogas methane content at time
from bottle “D” as mole fraction, a numeric vector.
E
biogas methane content at time
from bottle “E” as mole fraction, a numeric vector.
F
biogas methane content at time
from bottle “F” as mole fraction, a numeric vector.
These data are meant to be example data for cumBg
.
Reactors were 300 mL glass serum bottles with butyl rubber septa and screw caps.
Substrate was municipal wastewater sludge.
Methane and carbon dioxide contents were determined by gas chromatography using a thermal conductivity detector and normalised so methane and carbon dioxide sum to 1.0.
Data in s3voll
, s3compl
, s3volw
, s3compw
, and s3lcombo
are from the same bottles.
