Abstract:
1. A method of controlling a mostly-CO2 effluent stream in a pipeline, comprising: using at least at sensor to sense a state of said mostly-CO2 effluent stream along or at an outlet of said pipeline, and feeding an indication of said state back to a controller; and using the controller to control at least one of operating pressure and temperature of the mostly-CO2 effluent stream in order to (i) maintain said effluent stream as a single-phase liquid or a supercritical fluid stream in the pipeline using said indication of said state of said mostly-CO2 effluent stream and (ii) cause said mostly-CO2 effluent stream to move closer to a bubble-point line, while maintaining said mostly-CO2 effluent stream as the single-phase liquid or the supercritical fluid stream, when said indication of said state of said mostly-CO2 effluent stream indicates single-phase flow.
