Your write-up must demonstrate clarity of various metallurgical concepts in your reasoning and discussion. The criteria for assessing the essay are given in the "Marking scheme for the 1200-word essay.pdf" file. Note that Turnitin will compare your essay with all previously submitted essays and papers available in the literature including internet. Every sentence in this essay must be your own. You need to assume that every academic misconduct case will be reported and dealt as per university regulations'. Format: 11 point, Times New Roman font setting, single column format. Margins: Left, right, top and bottom - at least 1.5 cm Guidelines on writing the report: Please make sure that your report is interesting to read than just a collection of references in the form of a bibliography. See the marking scheme. The 1200-word limit translates to approximately 250 words for Introduction, 800 words for the Main body text and 150 words for the Conclusion and the Recommendation. Introduction: include the following information in the first introduction paragraph for your given element: crystal structure, melting point, solubility in FCC Ni, cost and density in comparison to Ni. Why it is considered in super alloys (its role in creep, fatigue, stress rupture properties as well as oxidation and hot corrosion resistance.). The overall range used in the superalloy literature and compare with the range used for IN713C, IN738C, IN792, Rene80, IN100 and Mar M246. Main body text should contain reflective discussion on the literature review. Each paragraph should have two to four independent references that supports your thought process/arguments. Be quantitative in your discussion. Remember that the figure space allowed is only half of one column per element. References must be included but they do not count towards the 1200 word limit. Your papers must reflect state of the art knowledge. You should also include interaction of your element with other elements to let the reader know what to look for if the range of your element is changed. In the text you must not cite two or more references together at the end of any sentence. You need to comment on each paper, individually, and compare/contrast findings with another paper. Hence, there will be a separate sentence for each paper. Your overall conclusions must be based on such comparisons. Try to be quantitative wherever possible i.e., give specific ranges for each element. You would always want to compare it with the IN713C alloy composition. Most importantly, remember that I don't want you to define specialist metallurgical jargon or buzz words but demonstrate in your writing that you understand what the jargon or buzz words means. I don't want copy paste sentences from papers. It should be a convincing story in your own words supported by literature and you are developing quantitative opinions by evaluating contrasting/conflicting evidence. Paragraphs should contain a complete thought within a larger structure. Each paragraph is set apart by a distinct thesis sentence with supporting statements that either precedes or follows the sentence. Paragraph length is determined by the number of supporting sentences used to clarify the topic in a concise progression of thought. Each paragraph has a theme, and it conveys an argument. An argument may have two sides. Other authors may have different experience or point of view. This is clearly identified and put together in a logical and easy to understand way. Corroboration with other sources is always done. Only one reference cited at a time and three or more unique and credible references are cited per paragraph. At least one relevant example is given from a peer reviewed paper and is well justified in the text All figures and tables should also be numbered in sequence (e.g., Figure 1 etc.) and each should have a caption (and a reference, if necessary). Equations should be numbered (1), (2) etc. The text of your thesis should be written in the third person narrative form in most cases. For example, use "he" not "I" and "they" not "we." Use past tense for the purpose of style and ease of reading as well as formality. (http://www.cws.illinois.edu/workshop/writers/tips/thesis/) The use of subheads within a paper serves to highlight major points while adding a firm structure to the text and makes the paper more inviting to the reader's eye. Except for dimensions, numbers from one (1) to nine (9) that appear within the text of papers are to be spelled. Double digits appear numerically written thereafter. Conclusion: Conclusions must be in the bullet point format, quantitative in nature and originate from your reflective discussions. They can be generic for super alloys. Recommendation: Identify your recommendation and suggested range for your element to improve IN713C properties by reflecting on costs in comparison to Mar M246. REFERENCES Use the Vancouver referencing system¹. References should have the following elements: author(s); year of publication; title; and source (i.e., publisher and place of publication in the case of books and reports only). Book titles are underlined; titles of articles are enclosed with double quotation marks; journal titles are underlined. The journal title is followed by the volume number, then the number within the volume (or the month or season, depending upon the journal's style), and then the page numbers.

The last thirty years have seen a significant amount of research on the CO2 rusting of mild steel, and lately there has been a lot of curiosity about the topic of rusting in supercritical carbon dioxide. Supercritical capture of carbon dioxide and increased extraction of oil are the main subjects covered in the published literature (Choi et al., 2015). These subjects frequently involve "dry" gases, meaning that water only exists in trace amounts. Although because water during formation as well as high-pressure areas directly affect pipeline steel oxidation, steel made of carbon corrodes at a very high rate (≥ 20 mm/y) at high CO2 tension (from fluid and hypercritical CO2) with no safeguarding FeCO3 rust product layers forming (Choi and Nesic, 2017). For the purpose of limiting corrosion, the pipeline must be sufficiently dried out (water removed) upstream to avoid high corrosion rates and the breaking out of free water. Drying the stream of gas in the field would be too expensive, though (Sim et al., 2017). The method of corrosion of carbon steel remains unchanged regardless of extreme CO2 pressures; hence, using inhibiting agents to reduce weathering under high CO2 pressure settings may be a viable approach. Numerous studies have examined how different inhibitors function in the CO2-saturated fluid. The most common inhibitors employed by the petroleum and natural gas sectors to prevent CO2 corrosion are those based on imidazoline. Nevertheless, the majority of these investigations used low CO2 pressure settings associated with gas and oil pipelines (Turgoose et al., 2018). Publications addressing the effectiveness of inhibiting corrosion in supercritical carbon dioxide systems under high CO2 tension settings are hard to come by. Supercritical CO2 devices were utilized to assess traditional anti-corrosion agents, including the imidazoline family, alkenylsuccinic acidic substances, and quaternary ammonium compounds. None of these substances worked completely, although they all did lower the corrosion rate (Kappes et al., 2018). At a high pressure and high temperature of 80 bar CO2 and 70 oC, the anti-corrosion activity of imidazoline-based inhibitors was evaluated. Localized corrosion was brought on by inadequate inhibition from imidazoline-type inhibiting agents, and the inclusion of sulfate showed the possibility of even decreasing the extent of corrosion in comparison to imidazoline inhibitors (Paolinelli et al., 2019). Overall, studies reveal that the aspect of corrosion in CO2 environments have received significant amount of assessment from past studies. Thus, it stages the scene for a critical metadata analysis to be explored in due course of the study. 1.3Aim(s) 3 The aim is to demonstrate the effectiveness of corrosion inhibitors in carbon steel corrosion specifically in environments with rich content of carbon dioxide (CO2), in Carbon Capture and Storage systems (CCS), aiming to provide a deep understanding of inhibitor performance and its effect via metadata analysis. In simple terms, however, the aim of the study is to establish the effectiveness linking to corrosion inhibitors in the mitigation of corrosion over carbon steel pipelines used for the transportation of CO2 environments via metadata analysis. 1.4 Objectives The objectives of the study are as follows: To collect data from academic articles, book chapters, websites, and use metadata analysis to build new data that highlights key discoveries alongside, improvement pathways with regard to replacing carbon-based environmentally degrading corrosion inhibitors with potentially less harmful alternatives. In explaining objective one above predominantly, the gathered/processed data will emanate from corrosion related experimental tests such as: (a) Electrochemical impedance Spectroscopy (EIS) (b) Linear polarization Resistance (LPR) and (c) Weight loss (WL). Therefore, the first objective is main to identify appropriate studies on the problem matter. In line with the objective above other sub-objectives are going to be considered as explicated next: a) To assess types of corrosion inhibitor that have been applied in various studies not to mention those that incorporate inorganic, organic, and hybrid inhibitors to determine their effectiveness in environments involving CO2. b) To quantify and comparatively analyse the rate of reduction of corrosion rate attained by varying corrosion inhibitors in CO2 environments in context of the findings established in different literature c) To investigate the impact of environmental factors related to CO2 concentration, pressure, temperature, and pH on the activity of corrosion inhibitors as expressed in selected/different studies 1.5 Report Layout The report consists of the following chapters: Chapter one which presents the introduction, research questions, aims, and objectives, and background review. Chapter two documents a theoretical framework aimed to present general information regarding carbon capture including storage (CCS) and the manner in which it could have an impact on the CCS performance. Chapter three addresses the situation of inorganic inhibitors and chapter four address the issue of organic inhibitors. Chapter five regards an assessment of the Paris Agreement 2015 featuring general information on the net zero and the manner in which it related to the corrosion inhibitors, and the manner in which inhibitors could assist to attain the net zero. Chapter six serves as the conclusion where comparison in the case of cathodic and anodic as well as mix inhibitors including mix inhibitors is to be conducted and establish the one that proves maximum efficiency. The captures also document about green inhibitor and the manner it could serve as an optimum alternative to attain the net zero. 4 Chapter 2: Theoretical Background 2.1 Introduction The focus of this chapter is to discuss the key theoretical background guiding the study and to elaborate on the impact of corrosion on CCS systems. The first section discusses the theoretical background adopted in the research. Thereafter, the effects of corrosion on CCS systems and the broader climate change are discussed. 2.2 Theoretical Background In this chapter a brief theoretical background has been presented to have an understanding of past studies regarding corrosion inhibitors effectiveness on carbon steel pipeline transporting CO2 environment. Comparisons and contracts across literature have been captured too. The Javidi et al. (2018) study examined the effectiveness of imidazoline derivation inhibitors of rust in preventing carbon steel from corroding in CO2 when hydrogen sulfide and iron carbonate scale were present. One of the most popular methods for preventing the corrosion of carbon steel by CO2 in the energy industry is the application of corrosion inhibitors. The film creation procedure used another imidazoline version as an anti-corrosion compound to safeguard the outermost layer. The study material was API 5L X65 carbon steel that was extracted from a damp gas distribution pipeline. Iron carbonates, a result of corrosion, coated the innermost layer of the pipeline. To investigate the efficacy of the inhibitory agents, Tafel polarisation and electrochemical impedance spectroscopy were implemented in a CO2-saturated 3.5-pound sodium hydroxide buffer. The results indicated that the presence of the iron carbonate coating lowered the inhibitory efficiency. Furthermore, the presence of H2S gas resulted in a decrease in inhibitory adsorption on the layer closest to the surface, resulting in a decrease in the inhibitor's effectiveness. Consistent with the aforementioned investigations, Chauhan et al. (2022) report that the carbon collection and preservation process effectively reduces atmospheric carbon dioxide pollution. When employing CCS technology, supercritical (SC) CO2 is a major risk because it damages pipelines. Steel pipes corrode as a result of a reaction between water contamination and CO2 gas, resulting in the formation of corrosive species such as carbonic acid (H2CO3). Three solutions are being utilized to solve this issue: (i) using corrosion-proof alloys (CRAs); (ii) using corrosive regulators; and (iii) using iron carbonate (FeCO3) protective coatings. Applying chemical compounds that interact with corrosive media that breakdown in the surroundings and adsorb on the desired metallic surface is one of the most crucial techniques for mitigating corrosion. A review of the several organic inhibitors of corrosion that are frequently used to stop SC CO2 rusting is the goal of this paper. This paper emphasizes the importance of finding greener inhibitor substitutes and considers various possible research directions. The researcher sought to examine the process by which SC CO2 corrodes, the variables influencing the chemistry of inhibiting agents, and their limitations. The use of computer algorithms to forecast restricting behavior is also included throughout this paper. This review, which highlights the 5See Answer
