Abstract:
본 발명은 상온 고압 또는 저온 저압의 액화 이산화탄소를 저장할 수 있는 저장용기를 수송선박에 부착 및 탈착할 수 있게끔 제작하고, 이를 플로우팅 도크(Floating Dock) 개념을 적용한 수송선에 얹어 육상의 항구로부터 해양의 저장지까지 수송하는 새로운 개념의 액화 이산화탄소 수송선에 관한 것이다. 본 발명에 따르면 다음과 같은 효과가 발생한다. 첫째, 수송선이 이산화탄소 적하역 및 주입 기간 동안 항구 또는 저장지에 머무르지 않아도 된다. 즉, 수송선의 계류시간을 획기적으로 줄여 수송효율을 극대화 할 수 있다. 둘째, 육상의 항구와 해상의 저장지에 별도의 임시저장설비가 필요치 않다. 따라서 대규모 임시저장설비 투자비를 절감할 수 있다. 셋째, 저장용기를 탑재하지 않은 수송선은 일반화물 운반선이나 컨테이너 운반선으로 활용하는 등 다목적으로 이용될 수 있다. 넷째, 수송선과 저장용기가 독립적으로 분리되어 제작 및 운용되므로 제작 및 유지보수에 유리하다.

PURPOSE: A transfer process simulator for carbon dioxide marine underground storage is provided to reduce the negative effect of a solid luggage in transfer and to prevent the blocking of a fluid system. CONSTITUTION: A transfer process simulator for carbon dioxide marine underground storage comprises a reservoir(10), an inlet part(20), a high-pressure pump(30), an accumulator(40), a first cooler(50), a heater(70), a simulation period test part(80), and a second cooler(100). The reservoir is formed into a pressure storage container in order to store the carbon dioxide in the liquid state. The inlet part is communicated to the main pipe(27) formed on one side of the reservoir. The high-pressure pump transfers the liquid carbon dioxide into an experiment device. The accumulator is connected to the outlet side of the high-pressure pump. The first cooler is connected to the accumulator. The heater heats in order to change the carbon dioxide to the supercritical state. Carbon dioxide of an over-cooler liquid state or a supercritical state is flown into the test part. The second cooler is connected to the simulation period test part.

PURPOSE: A pipeline transfer process simulator for carbon dioxide marine underground storage is provided to reduce the manufacturing cost of an experiment device by configuring the experiment device performing a reservoir role using a pipe of a large diameter instead of a high pressure container. CONSTITUTION: A pipeline transfer process simulator for carbon dioxide marine underground storage comprises a low-pressure pipe reservoir(10), an inlet part(20), a high-pressure pump(30), an accumulator(40), a first pressure adjusting valve(50), a cooler(60), a heater(70), a simulation period test part(80), and a second pressure adjusting valve(90). The low-pressure pipe reservoir is formed into a pipe shape in order to store carbon dioxide in a liquid state. The inlet part is connected to one side of the low-pressure pipe reservoir with a main pipe(27). The high-pressure pump transfers the liquid carbon dioxide into an experiment device. The accumulator is charged with high pressure gas in order to suppress the pulsation generated by the high-pressure pump. The first pressure adjusting valve re-suppresses the pulsation by controlling the pressure of the carbon dioxide. The cooler changes the carbon dioxide into a subcooled liquid state. The heater heats in order to change the carbon dioxide into a supercritical state. The simulation period test part is connected to the heater. The second pressure adjusting valve is connected and installed between the simulation period test part and the low-pressure pipe reservoir.
