Biogas Volume and Methane Content from Batch Bottles

Description

Biogas volume and methane content measurements from three batch bottles, organized in a “long” format.

Usage

data("s3lcombo")

Format

A data frame with 21 observations on the following 4 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.

vol.ml

volume of biogas removed at time in mL, 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 300 mL glass serum bottles with butyl rubber septa and screw caps. Substrate was municipal wastewater sludge. Volume was measured using syringes. 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.
