Dryer Switching Valve
Cracked gas leaving the compression train is saturated with water
that must be removed before fractionation. Without drying,
formation of hydrates and ice could cause damage to downstream
equipment. Continuous water removal requires multiple
adsorption beds. Switching valves are critical for continuous
operation between active and regenerating adsorption beds.
The valves responsible for switching dryer beds are exposed
to high cycles between repairs requiring high reliability. Poorly
performing switching valves can create bed disturbance and
damage adsorption beads. Response to setpoint and overshoot are
contributors to dryer inefciency. Switching valve design should
incorporate high-cycle and setpoint requirements to ensure dryer
efciency.
Incorporating Fisher control valve
assemblies from Emerson into your
high-cycle applications can have
significant benefits. Click on or scan
