Economic feasibility of CO2 capture from oxy-fuel power plants considering enhanced oil recovery revenues

Indonesia memiliki power plants yang tersebar di berbagai daerah baik milik PLN ataupun perusahaan swasta (Non PLN). Setiap perusahaan akan mengemisikan Karbon dioksida (CO2) dari hasil pembakaran pada power plant. Sebagai suatu polutan, CO2 memiliki potensi untuk digunakan pada proses industri seperti Enhanced Oil Recovery (EOR). CO2 EOR merupakan suatu usaha meningkatkan produksi minyak dengan cara injeksi CO2 ke dalam suatu sumur produksi tahap tersier. CO2 EOR dapat diterapkan di Indonesia dikarenakan terdapat beberapa power plants (sources) dan perusahaan minyak (sinks), khususnya di Jawa Timur. Hal ini memungkinkan untuk dapat mendistribusikan CO2 dari sources menuju sinks menggunakan perpipaan. Akan tetapi untuk mengaplikasikannya, dibutuhkan biaya (cost) CO2 captured, perpipaan, dan fasilitas EOR. Cost tersebut bergantung pada jumlah CO2 yang dialirkan, jarak dan teknologi yang digunakan, sehingga dibutuhkan optimisasi dikarenakan adanya variasi jumlah CO2 dan jarak. Dalam hal ini variabel optimisasi yaitu jalur perpipaan dan mass flowrate CO2 captured. Terdapat tujuh CO2 sources dengan kapasitas dan lokasi yang berbeda. Selain itu, terdapat tujuh sinks dengan kebutuhan injeksi CO2 yang berbeda pula. Hasil optimisasi menunjukkan CAPEX dan OPEX minimal. Nilai CAPEX dan OPEX setiap source bergantung pada jarak antara source dan sink beserta jumlah mass flowrate CO2 yang didistribusikan. Adapun source CO2 yang terpilih yaitu source 1,3,4 dan 7. Source yang tersisa (2, 5

The Impact

Partially Hydrolyzed Polyacrylamide (HPAM) is the polymer most used in chemical enhanced oil recovery (cEOR) processes and it has been implemented in several field projects worldwide. Polymer injection has shown to be an effective EOR process. However, it has not been implemented massively due to HPAM polymer's limitations, mostly related to thermal and chemical degradation caused by exposure at high temperatures and salinities (HTHS). As an alternative, a new generation of chemically stable monomers to improve the properties of HPAM has been assessed at laboratory and field conditions. However, the use of enhanced polymers is limited due to its larger molecular size, large-scale production, and higher costs. One of the alternatives proposed in the last decade to improve polymer properties is the use of nanoparticles, which due to their ultra-small size, large surface area, and highly reactive capacity, can contribute to reduce or avoid the degrading processes of HPAM polymers. Nanoparticles (NPs) can be integrated with the polymer in several ways, it being worth to highlight mixing with the polymer in aqueous solution or inclusion by grafting or chemical functionalization on the nanoparticle surface. This review focuses on hybrid nanomaterials based on SiO2 NPs and synthetic polymers with great EOR potential. The synthesis process, characterization, and the main properties for application in EOR processes, were reviewed and analyzed. Nanohybrids based on polymers and silica nanoparticles show promising results in improving viscosity and thermal stability compared to the HPAM polymer precursor. Furthermore, based on recent findings, there are great opportunities to implement polymer nanofluids in cEOR projects. This approach could be of value to optimize the technical-economic feasibility of projects by reducing the polymer concentration of using reasonable amounts of nanoparticles. However, more significant efforts are required to understand the impact of nanoparticle concentrations and injection rates to support the upscaling of this cEOR technology.

Adsorption Mechanisms

In the Enhanced Oil Recovery (EOR) methods, particularly in surfactant flooding, many tests have been performed, many scientific papers have been written and many findings have been found; however, there are still a lot of questions without any answers. Some of them are the interactions between the different reservoir components and the chemical flooding that are used in the EOR process. Nowadays, the main problem in the petroleum industry is the economic feasibility. Some authors report that the surfactant lost by the adsorption in the porous media increases the amount of surfactant that is needed. Understanding and controlling the amount of surfactant adsorbed directly, affects the project economics. It is crucial to the economic success of an EOR project that adsorption is reduced in the project design; to do so it requires an understanding of surfactant adsorption mechanisms. One of the factors that affect the surfactant adsorption in porous media is the mineralogy of the reservoir by the Cation Exchange Capacity (CEC) due to clays minerals present in the mineral composition of the reservoir.
