CO 2 through the hydrogen manufacturing process in the refinery generates at about 100, 000 tones per year typically. A small-medium size CO 2 geological storage in a distributed CCS plant is needed for the CO 2 in the refinery and a research work commenced in 2010. In the research work, several subjects have been examined about the geological structure as well as the surface equipments to make clear the distributed CCS plant in the refinery processes. Those subjects are bundled to aim to

The research includes the simulation for the CO 2 movement in the geological storage aquifer in the model field. Simulation, where the TOUGH2 code was used, was carried out in the model field in a case of an amount of 100,000 tones per year of CO 2 into a shallow aquifer. TOUGH2 code with the parameters as suitable to the micro-bubble as possible was tentatively used and it can come to a conclusion that the CO 2 in micro-bubble will be stored much safely because the smaller buoyancy of the CO 2 micro-bubble is expected. The simulation results inferred that gaseous CO 2 is stored in the shallow reservoir in the model field and no leakage is detected during the 20 years injection period.
