Optimization of carbon dioxide (CO₂) captured and distribution for enhanced oil recovery

In Indonesia, there are many power plants either owned by PLN or private company (non PLN) with varying electricity. The production of electricity will incur environment negative impact due to carbon footprint. As pollutant or byproduct, carbon dioxide (CO₂) has economical potential becoming a raw material or other industrial process such as enhanced oil recovery (EOR). CO₂ EOR is an effort to enhance oil recovery by injecting CO₂ at tertiary stage of oil production. CO₂ EOR can be applied in Indonesia, because there are a lot of power plants (sources) and oil companies (sinks), especially in East Java. It has possibility to transport CO₂ from power plants to oil companies through pipelines. However, it required cost of CO₂ capture, pipelines and EOR facilities. The cost depends on the amount of CO₂ demand and supply, distance and technologies. Therefore, it should be optimized due to variation in the amount of CO₂ and distance. The optimization variables are pipelines path and CO₂ captured mass flowrate. There are 7 CO₂ sources with different both capacities and locations. On the other hand, there are 7 oil companies (sinks) with different CO₂ injection demand. Optimization result shows minimum CAPEX and OPEX. The CAPEX and OPEX values of each source depend on the distance between source and sink as well as the amount of CO₂ mass flowrate. The chosen sources of captured CO₂ are source 1, 3, 4 and 7. The remaining sources are not utilized due to cost consideration.
