Methane Content of Biogas
Description
Methane content (biogas composition) measurements from 15 batch reactors.
Usage
data("comp2")
Format
A data frame with 360 observations on the following 3 variables.
bottle
identification code, a unique value for each reactor in the dataset. A factor with levels
1_1
,1_2
,1_3
,2_1
,2_2
,2_2
, ... through5_3
. The first number indicates the sample, the second the replicate.days
elapsed time of mass measurements (from reactor setup) in days, a numeric vector.
CH4.conc
biogas methane content as a mole fraction, excluding water and all other gases other than carbon dioxide, a numeric vector
Details
These data are meant to be example data for multiple functions, e.g., interp
, cumBg
, or summBg
.
Reactors were 500 mL or 1000 mL glass serum bottles with butyl rubber septa and screw caps.
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 vol2
, comp2
, and setup2
are from the same reactors.
