Manometric Sorption Test Facility
One of today's pressing issues associated with fossil fuel consumption is
how to curb greenhouse gas emissions, chiefly CO2. NETL research focuses
on ways to capture CO2 from power plant fuel streams and flue stack emissions,
and safely store (or sequester) it into geological formations such as coal
bed strata , natural gas fields, or saline formations.
NETL's Manometric Sorption Test Facility aids these efforts by applying elevated
temperature (from 55ºC to 300ºC) and pressure (up to
3,000 psig) to coal samples. Under these conditions, researchers study changes
to the CO2 or other fluids being absorbed or adsorbed by the sample, all with
a precision of 0.1 psi. In this manner, the sorbent capacity of a particular
coal sample can be calculated and its usefulness for future carbon sequestration
can be gauged.
NETL has a wide range of analytical and diagnostic instrumentation available
to support this type of analysis.
- Reference and sample cells (50 cc)
- Constant temperature bath (± 0.01 ºC)
- Vacuum pump
- Gas regulator
- Syringe pump
- Data acquisition board
- Computer interface
This facility is used for characterization of the sorption capacity of coals
The manometric/volumetric apparatus includes the reference (R) and sample (S) cells, a
temperature bath (B),
a vacuum pump (V), a gas regulator (G), a syringe pump, and
The measurements of the temperature (T) and the pressure (P)
of the sorbent in the
used to determine the mass of the fluid sorbed by the sample.
