Methane Content of Biogas from Batch Reactors

Description

Methane content (biogas composition) measurements from three batch bottles, organized in a “wide” format.

Usage

data("vol")

Format

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.

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. 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.
