We have updated a simple polyvinyl chloride plastic canister design by adding
internal headspace temperature measurement, and redesigned it so it
is made with mostly off-the-shelf components for ease of construction.
Using self-closing quick connects, this basic canister is mated to
a zero-head manometer to make a simple coalbed methane desorption system
that is easily transported in small aircraft to remote localities.
This equipment is used to gather timed measurements of pressure, volume
and temperature data that are corrected to standard pressure and temperature
(STP) and graphically analyzed using an Excel® based spreadsheet. Used together these elements form an effective, practical
canister desorption method.
