strawComp {biogas}

Methane Content of Biogas

Description

Methane content (biogas composition) measurements from 12 anaerobic batch reactors with straw for substrate.

Usage

data("comp")

Format

A data frame with 63 observations on the following 4 variables.

bottle

identification code, a unique value for each reactor in the dataset. Integer with all values from 1 to 12.

date.time

date and time of mass measurement, a POSIXct object.

time

elapsed time of mass measurements (from reactor 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

Details

These data are meant to be example data for cumBg. Reactors were ca. 600 mL glass serum bottles with butyl rubber septa and screw caps. Pressure was measured using an electronic manometer. Data in strawMass, strawSetup, and strawPressure are from the same reactors.
