3.5.3 Controllers and Internal Components of Gas–Oil
Separators
Gas–oil separators are generally equipped with the following control
devices and internal components [4].
Liquid Level Controller
The liquid level controller (LLC) is used to maintain the liquid level inside
the separator at a fixed height. In simple terms, it consists of a float that
exists at the liquid–gas interface and sends a signal to an automatic
diaphragm motor valve on the oil outlet. The signal causes the valve to
open or close, thus allowing more or less liquid out of the separator to
maintain its level inside the separator.
Pressure Control Valve
The pressure control valve (PCV) is an automatic backpressure valve that
exists on the gas stream outlet. The valve is set at a prescribed pressure.
