%description
High- and low-level functions for processing biogas data and predicting
biogas production. Molar mass and calculated oxygen demand (COD') can be
determined from a chemical formula. Measured gas volume can be corrected
for water vapor and to (possibly user-defined) standard temperature and
pressure. Gas quantity can be converted between volume, mass, and moles.
Gas composition, cumulative production, or other variables can be
interpolated to a specified time. Cumulative biogas and methane production
(and rates) can be calculated using volumetric, manometric, gravimetric,
or gas density methods for any number of bottles. With cumulative methane
production data and data on bottle contents, biochemical methane potential
(BMP) can be calculated and summarized, including subtraction of the
inoculum contribution and normalization by substrate mass. Cumulative
production and production rates can be summarized in several different
ways (e.g., omitting normalization) using the same function. Biogas
quantity and composition can be predicted from substrate composition and
additional, optional data. Lastly, inoculum and substrate mass can be
determined for planning BMP experiments.
