EXPERIMENTAL DEVICE FOR A SAFETY ANALYSIS OF BYPASS PIPELINE TRANSPORTING PROCESS FOR CO2 MARINE GEOLOGICAL STORAGE, CAPABLE OF PREVENTING A BLOCKADE OF A FLUID SYSTEM

摘要

PURPOSE: An experimental device for a safety analysis of bypass pipeline transporting process for CO2 marine geological storage is provided to diminish negative influences of solid impurities in a transporting process by examining the influences of the impurities influencing to the transporting process of carbon dioxide of high pressures, middle-low temperatures, and high amount flux.;CONSTITUTION: An experimental device for a safety analysis of bypass pipeline transporting process for CO2 marine geological storage comprises a first evaporator(2), a first reciprocating high-pressure compressor(3), a first accumulator(4), a first pressure regulator(5), a high-pressure heat exchanger(6), a liquid feeder(7), a first flow rate adjustment valve(10), a reactor(11), an impurity flowing unit, and a test unit(23). The first evaporator heat exchanges liquid carbon dioxide supplied from a liquid carbon dioxide reservoir(1) with atmosphere, thereby converting into gaseous carbon dioxide. The first reciprocating high-pressure compressor compresses the gaseous carbon dioxide has passed through the first evaporator by high pressures. The first accumulator reduces pressure pulsation of the gaseous carbon dioxide of high pressures discharged from the first reciprocating high-pressure compressor. The first pressure regulator depressurizes the pressure of the gaseous carbon dioxide of high pressures to become the pressure required for an experiment. The liquid feeder accommodates the liquid carbon dioxide of high pressures has passed through the high-pressure heat exchanger and prevents the liquid carbon dioxide from being gaseous through an evaporation.;COPYRIGHT KIPO 2012
