UQGDBiogas {biogas}

Biogas Volume and Mass Loss from BMP bottles

Description

Gas density biochemical methane potential (GD-BMP) measurements for 9 batch anaerobic bottles.

Usage

data("UQGDBiogas")

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.

time.d

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

vol

measured biogas volume at the end of a sampling interval, 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.

Details

These data are meant to be example data for calcBgGD, for gas density-based determination of biogas production (GD-BMP). Reactors were glass serum bottles with butyl rubber septa. Masses were measured with an analytical balance. Data in UQGDSetup are from the same bottles.

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