UQGravBiogas: Mass Loss and Biogas Composition from BMP bottles

In biogas: Process Biogas Data and Predict Biogas Production

Mass Loss and Biogas Composition from BMP bottles

Description

Gravimetric biochemical methane potential measurements for 9 batch anaerobic bottles.

Usage

data("UQGravBiogas")

Format

A data frame with 135 observations on the following variables.

id

identification code, a unique value for each bottle in the dataset. A factor.

day

elapsed time of measurements (from bottle setup) in days, a numeric vector.

mass.init

total bottle mass prior to biogas venting in g, a numeric vector.

mass.final

total bottle mass after biogas venting in g, a numeric vector.

xCH4

biogas methane content as a mole fraction (normalized so methane and carbon dioxide sum to 1.0), a numeric vector.

Details

These data are meant to be example data for calcBgGrav, for gravimetric determination of biogas production. Reactors were glass serum bottles with butyl rubber septa. Masses were measured with an analytical balance. Data in UQGravSetup are from the same bottles.

Source

Measurements were made by Sergi Astals and are described in the following paper.
