Methane content (biogas composition) measurements from three batch bottles, organized in a “long” format.
1 | data("s3compl")
|
A data frame with 14 observations on the following 3 variables:
id
identification code, a unique value for each bottle in the dataset.
time.d
elapsed time of mass measurements (from bottle setup) in days, a numeric vector.
xCH4
biogas methane content as a mole fraction, excluding water and all other gases other than carbon dioxide, 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.
