Used to remove sulfur dioxide and nitrogen oxide from the gases emitted from the combustion of coal in power stations.
The facilities don’t reduce at all the emissions of carbon dioxide or the particulates and only partially reduce the emissions of sulfur dioxide and nitrogen oxide.
See also wet scrubbers.
Gas that is left over after fuel is burned and which is disposed of through a pipe or stack to the outer air
A pipe through which gases and smoke escape from burning coal
Pressure at the wellhead with well flowing
A well that produces oil or gas by its own reservoir pressure rather than by use of artificial means (such as pumps).
In time the flowing tubing pressure of a gas well may decline and further compression may be needed
The pressure of the flowing well measured at the intake point in the borehole.
The ability to monitor bottomhole flowing pressure in pumping oil wells provides important information regarding both reservoir and artificial lift performance. Converting surface pressure measurements to bottomhole is currently accomplished by locating the fluid level in the annulus using a sonic device and then applying a correlation to estimate the density of the gas-cut liquid column above the perforations
