Methods of Enhanced Oil Recovery (EOR) from an oil reservoir by COflooding are disclosed. One method comprises producing a well stream from the reservoir; separating the well stream into a liquid phase and a gas phase with a first gas/liquid separator, wherein the gas phase comprises both COgas and hydrocarbon gas; cooling the gas phase with a first cooler; compressing the gas phase using a first compressor into a compressed stream; mixing the compressed stream with an external source of COto form an injection stream; and injecting the injection stream into the reservoir. Systems for EOR from an oil reservoir by COflooding are also disclosed.

A system for separating an input fluid flow comprising gas and liquid into separate gas and liquid flows is provided. The system includes a primary separator configured to receive the input fluid flow and to separate the input fluid flow into a primary separator liquid output flow and a primary separator gas output flow, a first secondary inline separator connected downstream from the primary separator to polish the primary separator gas output flow, a second secondary inline separator connected downstream from the primary separator to polish the primary separator liquid output flow, a system gas outlet, a system liquid outlet, a primary separator gas output valve on the primary separator gas output flow, and a control system configured to receive measurements of liquid level within the primary separator, and identify, using the received measurements, whether a position of the primary separator gas output valve is to be changed.
