FIELD: oil and gas industry.
SUBSTANCE: method and system are intended to optimise carbon dioxide cut-off operations and are oriented towards control of operating parameters for a ground-based installation for carbon dioxide compression (CO2) or pipeline for maintenance of CO2 flow in liquid or supercritical state during transportation to the cut-off point. The methods and installation use sensors to determine whether the flow is single-phase or double-phase, and feedback coupling to regulate pressure and/or temperature at the pipeline input.
EFFECT: reduced losses of useful capacity generated by the power plant at separation and compression of CO2 flow passing through the pipeline.
