The Effective Conversion Of Co2

Conservation of Mass and Energy are the hallmarks of our natural world, and as we progress as a civilization there is an ever increasing need to satisfy our growing demand for energy. This leads to the present need for more innovative solutions that are able to solve the world 's energy needs within the confines of the natural laws we live with. The Earth 's petrochemical reserves represent a finite amount of available, extractable, energy that mankind is able to harvest. In order to continue meeting the need for our civilization to thrive, or at the least, maintain, itself; we have to continue, as chemical engineers, providing new and novel ways to support the world with ways to implement Mass and Energy transportation. The main issue at hand is that newer, sustainable, energy is needed.

In an attempt to meet climate emissions goals, scientists are obtaining and using carbon dioxide emitted by power plants and other sources. In theory, carbon dioxide is easy to capture. This is because it is acidic, and it reacts effortlessly with simple bases like amines. In practice, however, amine scrubbing, the method used by some power plants to capture carbon dioxide for cleaning flue gases, is defeated because it encloses the greenhouse gas in water-based solutions. An abundance of energy is required to heat these great amounts of water in order to release the carbon dioxide that was captured and to renew the amines.

Later, the move gasoline is cooled to 212oC and enters into the Low Temperature (LT) converter in which Copper Oxide (CuO) and Zinc Oxide (ZnO) catalysts are used. due to the presence of CO2, the used catalyst within the NH3 Synthesis loop might be poisoned; hence, it should be eliminated. consequently, CO2 is eliminated inside the CO2 removal unit with the aid of using MDEA (Methyl Di Ethanol Amine) under low temperature and pressure. In case of getting lines of CO and CO2 in the process fuel, it is important to transform them into Methane CH4 that happens within the methanation unit by way of using a Nickel catalyst at nearly 350 °C consistent with the subsequent exothermic response.

With the increasingly global acceptance that carbon dioxide (CO2) is contributing to an irreversible change in climate, a progressively growing international population and an ever more reliance on fossil fuels, a way of reducing carbon dioxide emissions into the atmosphere is essential. Currently renewable energies are not established enough to meet the demand that fossil fuels serve so that’s where carbon capture and storage (CCS) comes in.

CO2 is the most significant greenhouse gas, which mainly comes from the use of fossil fuels. Many people feel that content of CO2 in the atmosphere is the main reason for manmade global warming. The main sources of CO2 emissions involve electricity generation, industrial processes, fumes from transportation and commercial buildings and use. Emissions of greenhouse gases, such as CO2, to the atmosphere are expected to cause even more of a significant change in global climate (Davison, 2007). The main focus to try to reduce the amount of carbon dioxide in the atmosphere is to reduce the amount that is released from coal-fired power plants. Greenhouse gas emissions that involve the productions of electricity come from natural gas production and coal-fired power plant operations. Natural gas production accounts for twenty-four percent and coal-fired power plant operations accounts for seventy-five percent, while the other one percent is caused by other electricity generation operations. The main reason why coal-fired power plants have a higher percentage of emissions is because the sulfur content of coal is much higher than that of other fossil fuels (Jarmaillo et al., 2007). This proves that there is a great need to find an alternative fossil fuel to use instead of coal. Although coal is easy to mine, transport and process for the electricity generation process, it is also the

In this day and age, finding an alternate source of energy to fossil fuel is essential. Humans are using up fossil fuels, such as coal and oil, faster than they can be made naturally.This means that there will be a time when all of the fossil fuels will have been used to power . To prevent a world without energy, many alternative sources have been harnessed. Six different pathways for energies were found: solar power, biomass, geothermal power, hydropower, wind power, and nuclear power. All of these are much better alternatives to fossil fuels, as they reduce carbon emissions. Carbon dioxide is one of the greenhouse gasses in Earth’s atmosphere, which when created in excess, causes things such as global warming to occur. But when they are compared to each other, some seem better than others in many different ways. Although wind and hydropower are both promising alternative energies, wind power would be better for New Jersey, because it is space efficient, relatively cheap, and the turbines can be placed almost anywhere.

Carbon capture technology has been in use for several decades in the oil industry, however with environmental worries the technology is being developed to be implemented into power plants, as they are main source of CO2 emissions. There are three methods of Carbon capture: Post combustion capture, Pre combustion capture and Oxy-fuel combustion capture. The method used is dependent on the fuel being burnt and the percentage composition of the stack flue.

Carbon Dioxide is the main contributor to greenhouse gases in the global climate change. CO2 is released from power plants and vehicles all over the world. Approximately 62 million cars are registered in the US alone, according to the U.S. Department of Transportation. There are also 2,775 power plants in the US alone. 30,000 parts per million of Carbon Dioxide are released from the 700-degree Fahrenheit fumes into the atmosphere from the turbines at Moss Landing power plant along the California coast is an example of the amount of CO2 released from one single power plant. This new idea of technology would reduce the amount of the greenhouse gas CO2 being released into the atmosphere and would capture and store it in cement.

Carbon sequestration is a process involving the capture of excess CO2, either from the atmosphere or from human outputs such as power stations, followed by the disposal of said carbon dioxide by a one of range of means. This has the potential to vastly reduce the volume of carbon in the atmosphere and so mitigate the problem that humans cause by pumping huge amounts of CO2 into the atmosphere from large scale power stations, refineries and such like (Pacala & Socolow, 2004). Successful sequestration schemes are low-impact, long term and cost effective. The main branches of carbon sequestration include terrestrial, geological and anthropogenic.

Anthropogenic emissions of CO2 as well as their effects on the climate increase on a daily basis. With the current situation of things in the world, it is unlikely for renewable energy resources to replace fossil fuels as the major sources of energy anytime soon (Wennersten et al, 725). Therefore, Carbon capture and storage (CCS) seems to be one of the most viable options to reduce the current rate of anthropogenic emissions of CO2. Sustainability is a key factor in determining whether or not CCS becomes a major technology in limiting anthropogenic emissions of CO2. That is, the benefits of CCS should outweigh its costs. In this paper, I 'm going to look at carbon capture and its feasibility as a key factor in limiting anthropogenic emissions of CO2.

With the U.S. and other major emitters continuing to rely heavily on fossil fuels, it is clear that technology that addresses this dependence will be needed in order to meet emissions reduction targets. These technologies may include renewables (primarily wind and solar), increased energy efficiency, hydroelectric power generation, or carbon capture and sequestration technologies (CCS). While technological advances have continued and investment for both development and

Carbon capture technology is a relatively new solution that is currently being tested to create that long term solution we have been searching for. The thought is that if we capture the carbon dioxide before it is released into the atmosphere, we can store it and use it for energy later, and in doing this, prevent harmful emissions. Once it is captured, it can be stored and used for power in the future. On paper I think it is a great plan, but, is it going to deliver the results that it proclaims it will? Will it be a positive step forward for the environment? Is the new technology cost effective compared to the benefits that it

The shortage of energy is already one of crucial issues in some areas and it is spreading steadily across the globe. In addition, the vast majority of the consuming energy comes from nonrenewable fossil fuels, such as oil, natural gas, and coal, which threaten the damage of environment that can lead to the global warming. Therefore, it is required to find new renewable source of energy, which can entirely ensure sustainable system and provide the population with environmentally friendly, financially available and productive energy (Turner 1999). The methane gas (CH½) is the biogas that is abundant in nature; it is also produced anaerobically by recycling the materials as wood wastes, agricultural crops, municipal solid wastes, and wastes from food processing and aquatic plants and most effectively by concentrated animal wastes (Bingemer and et al. 1987). The biogas is widely adopted in many fields, such as heat and electricity production in industry, chemicals and proteins emitter, manufacturing the vehicle fuel. In addition, the methane has a significant role in agriculture; it is indispensable substance that can supply rural areas simultaneously with heat and electricity (Holm-Nielsen and et al. 2009). This paper suggests the methane gas as an alternative solution and evaluates the most proper area for opportunely utilizing it.

Several studies have investigated the effect of syngas on the structure of metallic Co catalysts.9-12 For instance, Karaca et al. investigated the effect of syngas on a CoPt/Al2O3 catalyst using X-Ray Diffraction (XRD).9 After reducing the catalyst in H2 at 623 K, XRD peaks were observed for face centred cubic (fcc) and hexagonal close packed (hcp) structures of metallic Co. After exposure to 20 bar of syngas at 493 K, the fcc XRD peaks became narrower over 5 hrs, which was suggested to be due to an increase in the particle size due to sintering of the Co metal phase. Over the subsequent 5 hrs this peak decreased in intensity and a new peak assigned to a carbide phase grew in. Therefore, the authors concluded that deactivation of the catalyst was due initially to sintering and then, over longer periods of time, to carbidisation.

CO2 is an important greenhouse gas (GHG) and emission of CO2 to the atmosphere needs to be reduced in order to mitigate climate change. It is imperative to device ways of proper CO2 utilization and storage. CO2 can be sequestered geologically as well as there are other ways of CO2 utilization which can be economically viable in places where geological storage is not the most optimal solution. In the present study, the primary focus is on the integration potential of two GHG abatement options, which are geological sequestration of CO2 and biological sequestration of CO2 via microalgae growth, harvest and conversion to bioproducts. There are several ways of microalgae conversion to an array of products, as discussed in the previous sections. The present study aims to quantify the techno-economic tradeoffs and optimize the entire supply-chain of CO2 utilization to ensure the most economically feasible alternative of CO2 usage. A multi-scale optimization framework is proposed. The mathematical framework is provided in Figure 2. The model takes into account the design of pipeline network for CO2 transport, different processing routes for microalgae conversion as well as CO2 geological storage. A case-study is considered to assess the optimal design of GHG capture, storage and/or utilization for the state of Texas in United States. Such an effort will help inform decision and policy makers the optimal pathway of CO2 storage and utilization procedures for a particular location.
