Purpose This paper aims to discuss opportunities for pairing the carbon dioxide (CO2) points of supply from stationary sources such as power plants, steel and cement production, coal to liquid plants and refineries, with potential oil reservoirs in China. Design/methodology/approach This study builds a linear optimization model to analyze the tradeoffs in developing CO2-enhance oil recovery (EOR) projects in China for a range of policy options to match points of supply with the points of demand (oil fields). The model works on optimizing CO2 application costs by meeting four principal components; CO2 storage, CO2 capture, transport costs and additional oil recovery. Findings This study reveals new opportunities and economic sources to feed CO2-EOR applications and offers reasonable options to supply CO2 for potential points of demand. Furthermore, power plants and coal to liquid industries had the most significant and economic contributions to potential CO2-EOR projects in China. Total annual emission reduction is expected to be 10% (based on 10 Gton annual emissions). The emission reductions and potential CO2 storage from the different industries as follow; 94% from power plants, 4% from biofuel and 2% from coal to liquid plants. Social implications Carbon capture and storage (CCS) is one practice aiming to reduce the amounts of anthropogenic emissions of carbon dioxide emitted into the atmosphere and reduce the related social costs. However, given the relatively high cost associated with this practice, coupling it with EOR could offer a significant financial incentive to facilitate the development of CCS projects and meet climate change objectives. Originality/value The model used in this study can be straightforwardly adapted to any geographic location where industry and policymakers are looking to simultaneously reduce CO2 emissions while increasing hydrocarbon recovery. The model is highly adaptable to local values in the parameters considered and to include additional local considerations such as geographic variation in capture costs, taxes and premiums to be placed on CO2 capture in so-called “non-attainment zones” where pollution capture make could make a project politically and economically viable. Regardless of how and where this model is applied, it is apparent that CO2 from industrial sources has substantial potential value as a coproduct that offsets its sequestration costs using existing, commercially available CO2-EOR technology, once sources and sinks are optimally paired.

Abstract One of the main problems in the use of solid fuels is inevitable formation of significant amounts of carbon dioxide. The prospects for reducing CO2 emissions (carbon capture and storage, CCS) are opening up with the use of new coal technologies, such as thermal power plants with integrated gasification (IGCC) and transition to oxygen-enriched combustion (oxyfuel). In order to study the efficiency of solid fuel conversion processes using carbon dioxide, thermodynamic modeling was carried out. Results show that difference between efficiency of fuel conversion in O2/N2 and O2/CO2 mixtures increases with an increase in the volatile content and a decrease in the carbon content. The effect of using CO2 as a gasification agent depends on the oxygen concentration: at low oxygen concentrations, the process temperature turns out to be low due to dilution; at high oxygen concentrations, the CO2 concentration is not high enough for efficient carbon conversion.

Carbon capture and storage (CCS) constitutes an extremely important technology that is constantly being improved to minimize the amounts of carbon dioxide (CO2) entering the atmosphere. According to the Global CCS Institute, there are more than 320 worldwide CCS projects at different phases of progress. However, current CCS processes are accompanied with a large energy and efficiency penalty. This paper models and simulates a post-combustion carbon capture system, that uses absorption as a method of separation, in Aspen Plus V7.2. Moreover, the CAPE-OPEN Simulated Annealing (SA) Capability is implemented to minimize the energy consumed by this system, and allow coal-fired power plants to use similar carbon capture systems without losing 20 to 40 % of the plant's output.

The Cost

For petroleum industries, CO2 can cause corrosion, and heating-value reduction. However, CO2 can be used to enhance the oil recovery for oil production. However, the amount of CO2 supply is not enough because the cost of carbon capture is high. The main sources of CO2 come from power generation. The technology to capture CO2 is carbon capture and storage or CCS. Currently, the effective technology to remove CO2 from the power plants is chemical absorption and chemicals used in this technology play a key role. Nowadays, the commercially used solvents are monoethanolamine (MEA). Nevertheless, it also has disadvantages such as low capacity and high energy requirement for regeneration thus making CCS costly. Therefore, many new solvents such as 2-(methylamino) ethanol or 2-MAE have been developed to improve efficiency and to reduce the cost of CO2 capture. Therefore, the objective of this work is to measure the solubility data of CO2 in a 5M aqueous solution of 2-MAE as a promising solvent at the temperature from 30 °C to 80 °C and CO2 partial pressures ranging from 5 to 100 kPa. The solubility results of CO2 in 2-MAE solution are compared with those of aqueous solution of MEA. In term of cyclic capacities, the results show that 2-MAE provides higher performance which is up to 86.8% and 150.9% higher than that of MEA at 15 and 100 kPa, respectively. Furthermore, the results present that the CO2 loading can increase as partial pressure increases and decrease at higher temperature. It can be concluded that an increase in cyclic capacity leads to the decrease in energy requirement for solution regeneration and liquid-circulation rate, leading to the reduction of the overall capital and operating costs and resulting in the decrease in cost of carbon capture.

Subject Carbon capture and storage technology. Significance Carbon capture and storage (CCS) is considered critical to achieving the ambitious reductions in greenhouse gas emissions set out in the 2015 Paris Agreement. CCS technology would allow power plants and industrial facilities to continue burning fossil fuels without pumping climate change-inducing gases into the atmosphere. However, deployment of CCS has been slow and the prospect of meeting the expectations placed upon it by the Paris climate negotiators is moving further out of scope. The recent cancellation of the Kemper CCS project in the United States is a bad sign for the future of the technology. Impacts Without faster deployment of CCS, many countries will struggle to meet their Paris Agreement emissions reduction pledges. If the rollout of CCS continues to falter, more wind and solar power will be needed to reduce carbon emissions. Absent a viable CCS model, it will be even more difficult to replace aged coal plants in the United States and other developed economies.

AbstractMolecular dynamics simulations were performed to study the bulk and interfacial properties of methane + n-decane, carbon dioxide + n-decane, and methane + carbon dioxide + n-decane systems under geological conditions. In addition, theoretical calculations using the predictive Peng-Robinson equation of state and density gradient theory are carried out to compare with the simulation data. A key finding is the preferential dissolution in the decane-rich phase and adsorption at the interface for carbon dioxide from the methane/carbon dioxide mixture. In general, both the gas solubility and the swelling factor increase with increasing pressure and decreasing temperature. Interestingly, the methane solubility and the swelling of the methane + n-decane system are not strongly influenced by temperature. Our results also show that the presence of methane increases the interfacial tension (IFT) of the carbon dioxide + n-decane system. Typically, the IFT of the studied systems decreases with increasing pressure and temperature. The relatively higher surface excess of the carbon dioxide + n-decane system results in a steeper decrease in its IFT as a function of pressure. Such systematic investigations may help to understand the behavior of the carbon dioxide-oil system in the presence of impurities such as methane for the design and operation of carbon capture and storage and enhanced oil recovery processes.

Fossil Fuel Power Plants

Climate change has been attributed to greenhouse gases with carbon dioxide (CO2) being the major contributor. Most of these CO2 emissions originate from the burning of fossil fuels (e.g. power plants). Governments and industry worldwide are now proposing to capture CO2 from their power plants and either store it in depleted reservoirs or saline aquifers (‘Carbon Capture and Storage’, CCS), or use it for ‘Enhanced Oil Recovery’ (EOR) in depleting oil and gas fields. The capture of this anthropogenic (man made sources of CO2) CO2 will mitigate global warming, and possibly reduce the impact of climate change. The United States has over 30 years experience with the transportation of carbon dioxide by pipeline, mainly from naturally occurring, relatively pure CO2 sources for onshore EOR. CCS projects differ significantly from this past experience as they will be focusing on anthropogenic sources from major polluters such as fossil fuel power plants, and the necessary CO2 transport infrastructure will involve both long distance onshore and offshore pipelines. Also, the fossil fuel power plants will produce CO2 with varying combinations of impurities depending on the capture technology used. CO2 pipelines have never been designed for these differing conditions; therefore, CCS will introduce a new generation of CO2 for transport. Application of current design procedures to the new generation pipelines is likely to yield an over-designed pipeline facility, with excessive investment and operating cost. In particular, the presence of impurities has a significant impact on the physical properties of the transported CO2 which affects: pipeline design; compressor/pump power; repressurisation distance; pipeline capacity. These impurities could also have implications in the fracture control of the pipeline. All these effects have direct implications for both the technical and economic feasibility of developing a carbon dioxide transport infrastructure onshore and offshore. This paper compares and contrasts the current experience of transporting CO2 onshore with the proposed transport onshore and offshore for CCS. It covers studies on the effect of physical and transport properties (hydraulics) on key technical aspects of pipeline transportation, and the implications for designing and operating a pipeline for CO2 containing impurities. The studies reported in the paper have significant implications for future CO2 transportation, and highlight a number of knowledge gaps that will have to be filled to allow for the efficient and economic design of pipelines for this ‘next’ generation of anthropogenic CO2.

Abstract: More than ever, the fate of anthropogenic CO2 emissions is in our hands. Since the advent of industrialization, there has been an increase in the use of fossil fuels to fulfil rising energy demands. The usage of such fuels results in the release of carbon dioxide (CO2) and other greenhouse gases, which result in increased temperature. Such warming is extremely harmful to life on Earth. The development of technology to counter the climate change and spreading it for widespread adoptions. We need to establish a framework to provide overarching guidance for the well-functioning of technology and mechanism development of Carbon Capture and Storage. Carbon capture and storage (CCS) is widely regarded as a critical approach for achieving the desired CO2 emission reduction. Various elements of CCS, such as state-of-the-art technology for CO2 collection, separation, transport, storage, politics, opportunities, and innovations, are examined and explored in this paper. Carbon capture and storage is the process of capturing and storing carbon dioxide (CO2) before it is discharged into the environment (CCS). The technology can capture high amounts of CO2 produced by fossil fuel combustion in power plants and industrial processes. CO2 is compressed and transferred by pipeline, ship, or road tanker once it has been captured. CO2 can then be piped underground, usually to depths of 1km or more, and stored in depleted oil and gas reservoirs, coalbeds, or deep saline aquifers, depending on the geology. CO2 could also be used to produce commercially marketable products. With the goal of keeping world average temperatures below 1.5°C (2.7°F) and preventing global average temperature rises of more than 2°C (3.6°F) over pre-industrial levels, CCS model should be our priority to be implemented with the proper economical map

Power Cycle

The energy generation from the fossil fuels results to emit a tremendous amount of carbon dioxide into the atmosphere. The rise in the atmospheric carbon dioxide level is the primary reason for global warming and other climate change problems for which energy generation from renewable sources is an alternative solution to overcome this problem. However, the renewables sources are not as reliable for the higher amount of energy production and cannot fulfil the world’s energy demand; fossil fuels will continue to be consumed heavily for the energy generation requirements in the immediate future. The only possible solution to overcome the greenhouse gas emission from the power plant is by capturing and storing the carbon dioxide within the power plants instead of emitting it into the atmosphere. The oxy-fuel combustion power cycle with a carbon capture and storage system is an effective way to minimize emissions from the energy sectors. The oxy-fuel power cycle can reduce 90–99% of carbon dioxide emissions from the atmosphere. Moreover, the oxy-fuel power cycles have several advantages over the conventional power plants, these include high efficiency, lesser plant footprint, much easier carbon-capturing processes, etc. Because of these advantages, the oxy-fuel combustion power cycles capture more attention. In the last decades, the number of studies has risen exponentially, leading to many experimental and demonstrational projects under development today. This paper reviews the works related to oxy-fuel combustion power generation technologies with carbon capture and storage system. The cycle concepts and the advancements in this technology have been briefly discussed in this paper.
