EXPERIMENTAL DEVICE FOR SAFETY ANALYSIS OF BY-PASS PIPELINE TRANSPORT PROCESS IN CO_2 MARINE GEOLOGICAL STORAGE

摘要

The present invention relates to an electrode sensor for realizing a flow pattern of a CO_2 pipe line, which is capable of detecting the flow pattern of two phase flows which may be generated in accordance with pressure inside a CO_2 transport pipeline and an outdoor temperature change in transmitting a large amount of CO_2 collected in a steel mill and a generator, and the like, on land, to a marine storage unit. An electrode sensor for realizing a flow pattern inside a pipe line of a CO_2 marine geological storage comprises: a sensor bar installed to cross a space inside a pipe; an outside connection line of which one end is connected to an electrode connection line through a sensor cap, and of which the other end is connected to a multiplexer outside the pipe; a multiplexer having a power feeder and a resistance measuring instrument installed therein, and to access or interrupt a connection between the power feeder and the outside connection line, or access or interrupt a connection between the resistance measuring instrument and the outside connection line; the power feeder to supply power to an electrode through the multiplexer and the outside connection line to heat the electrode; and the resistance measuring instrument to measure a resistance change in accordance with the time of the electrode through the multiplexer and the outside connection line.
