Spray column

Type of absorber in which the spraying of droplets ensure optimal con-
tact between the gas and the liquid.

Stage cut

The stage cut θ is defi ned as the fraction of the feed that fl ows through

a membrane:

Stefan-Boltzmann's law

A law describing the relation between the temperature of an object ( T )
and the energy ( J ) this body emits through blackbody radiation:

4

J = s ,

where σ is the Stefan-Boltzmann constant.

Stratigraphic trapping

See structural trapping.

Stripper

Equipment of an absorption process in which the absorbed gas is
removed/stripped from the solvent.
See also absorber.

Structural trapping

Structural trapping of CO 2 occurs when the caprock prevents the CO 2
from moving upward.
See also stratigraphic trapping.
