System and method to evacuate and capture various liquid and gas hydrocarbon fluids from meter provers

A system comprising:

• a pump or compressor comprising an inlet section and an outlet section;
• a first conduit configured to couple the inlet section to a discharge section of a meter prover after completing a calibration of an inline meter prover of an oil and gas flowline;
• a second discharge conduit configured to couple the outlet section of the pump or compressor to any one of a downstream section of the flowline, a containment pipeline and a pressure vessel;
• and
• a controller communicatively coupled to the pump or compressor and configured to cause the pump or compressor to perform operations comprising:
• pulling the fluid from an upstream section of the flowline or vessel, into the meter prover, wherein the fluid comprises a mixture of any of gases, liquids and solids,
• pulling the fluid from the discharge section of the meter prover at a first pressure,
• cross-compressing the fluid, to raise a pressure of the fluid from the first pressure to a second pressure higher than the first pressure,
• pumping the fluid at the second pressure into any one of the downstream section of the flowline, the containment pipeline and the pressure vessel, and
• stopping the flow of fluid responsive to determining that the fluid has been evacuated from the meter prover.
