9. A lube oil system comprising:
a reciprocating compressor comprising a crankcase;
a lube oil circulation system comprising:
a lube oil reservoir configured to store a first lube oil;
a tubing network connected to the lube oil reservoir and to the crankcase of the reciprocating compressor; and
a lube oil pump configured to pump the first lube oil throughout the tubing network;
a cylinder lubrication system comprising:
a cylinder lubricator oil reservoir configured to store a second lube oil; and
a cylinder lubricator connected to the cylinder lubricator oil reservoir and to a plurality of cylinders of the reciprocating compressor, the cylinder lubricator configured to distribute the second lube oil to the plurality of cylinders;
an intermediate flowline connecting the tubing network of the lube oil circulation system to the cylinder lubricator oil reservoir of the cylinder lubrication system;
a control system comprising a level sensor coupled to the cylinder lubricator oil reservoir, the level sensor configured to measure a liquid level in the cylinder lubricator oil reservoir, the control system configured to control flow of the first lube oil from the lube oil circulation system to the cylinder lubrication system through the intermediate flowline based on the liquid level in the cylinder lubricator oil reservoir measured by the level sensor wherein the control system comprises a flow element installed on the intermediate flowline, the flow element configured to reduce pressure of the first lube oil flowing through the intermediate flowline, the flow element comprising at least one of a pressure regulator or a restriction orifice.
