Abstract
Oil and gas well production flow is gathered in field common line manifolds and conducted through a separator to make a coarse separation of gas from liquid and minimize slug flow in the conduits leading from the manifolds to further separation, treatment and pumping facilities. A liquid level signal transmitter provides a signal to a valve controller which controls separate liquid and gas discharge flow control valves or a variable speed pump to maintain a set point level of liquid in the separator. Liquid level control is accomplished automatically by varying the flow from the fluid discharge conduit which is connected to the lower pressure flow line, which is usually the gas flow line. Manifold pressures may be sensed to prevent exceeding a predetermined pressure in the manifolds and the well flow lines.
