Unfortunately, the liquefying process consumes high amount of energy impacting negatively on the economic viability of the LNG business. Based on this, the current work assesses the selection of propane pre-cooled mixed refrigerant [C3 MR] and methane, ethane and propane [C1 -C3 ] refrigerant cascade system as a refrigerant with essential benefits in LNG production. The process was simulated using Aspen HYSYS, and its economic tool was used to carry out the techno economic analysis and estimate the duties of the two processes. The results obtained showed that the production cost were $20,345,490 and $114,796,200 for C1 -C3 cascade refrigeration system and C3 MR, respectively. The duty were 568.721 MW and 626.462 MW for the C1 -C3 cascade refrigeration system and C3MR, respectively. This shows that C1 -C3 cascade refrigeration system performed better than the C3 MR. Therefore, the former refrigerant is preferred in a liquefying process than the latter as it is cheaper, consumes less amount of energy and is more environmentally friendly.","PeriodicalId":355186,"journal":{"name":"Petroleum and Chemical Industry International","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114825862","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Biodiesel is one of the promising alternatives for the replacement of the conventional diesel. Currently about 36 billion liters of biodiesel has been produced globally by different countries using various feedstock such as edible oils, non-edible oils, algae oil, genetically modified microbes and waste sludge oils. Several techniques such as direct blending, microemulsion, thermal cracking and transesterification etc, have been used for production of biodiesel from various feedstock. The measure of the effectiveness of any technique depends on ease of operability and the percentage yield obtained at the end of the production process.

This increase is attributed to high demand, and favourable policy initaited by various government of the world including tax credit and subsidy in the quest to mitigate climate change. Nigeria government in 2007, gazetted the Nigerian Biofuels Policy aimed at promoting the utilization, importation and production of biofues in Nigeria. It encourages investment in biofuels through tax waiver including importation and exportation, waiver on import and customs duties, and insurance. The biomass resources of Nigeria include agricultural and residues, forest products and residues, and municipal solid wastes amounting to over 200 billion kg/yr with energy potential greater than 61 Mtoe. To realize this energy potential, there is a need for the Nigerian government to implement its biofuel policy completely, and to expand the current approved biomass (cassava, sugarcane, palm oil, jatroph, and cellulosic materials) for biofuel production to include the use of lignocellulosic biomass, non-edible oil other jatropha, and algae.

The chemical recycling technology was used to transform PET into practical items with a sizable and successful industrial application. In order to model the chemical neutral hydrolysis depolymerization process of PET plastic wastes utilizing a continuous stir tank reactor for the synthesis of pure terephthalic acid [TPA] and EG for commercial use, this work used ASPEN PLUS V10. The data for the modeling came from an experimental chemical recycling project employing the neutral hydrolysis process to depolymerize PET bottle trash. PET waste was degraded using excess water [H2 O] and zinc acetate [Zn [Ac]2] as the active catalyst. A mean PET particle size of 127.5 m, 1000 kg/h of PET depolymerized at an H2 O: PET [w/w] ratio of 8:1, 513.15 K temperature, 32.0 bar pressure, and 0.5 h residence time were the reaction's ideal working parameters. Regarding PET, it is a first-order reaction. The reaction yielded 782.72 kg/h of TPA, 292.43 kg/h of EG, and a depolymerization of PET of 90.54%. TPA and EG had selectivity of 0.7280 and 0.2720, respectively. Filtration, distillation, and crystallization techniques were used to separate the mixture of components. The heat from the conveyance, reaction, and separation processes was obtained. This effort increased the yield of TPA, the amount of water removed for reuse, the amount of EG generated, and the amount of processing heat required. The procedures and their operating circumstances can be used to scale up commercial processes in the future.","PeriodicalId":355186,"journal":{"name":"Petroleum and Chemical Industry International","volume":"68 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121089020","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The demand for renewable diesel is increasing especially due to its high qualities including cetane, cloud point, oxidative stability, cold flow and can be produced and transported using the existing refinery facilities. The current work discusses the feedstocks used in renewable diesel production, catalysts, methods of production, factors affecting the production, reaction pathway/kinetics of renewable diesel production, and analysis of renewable diesel based on existing literature.

This study aims to determine the optimal values for the variables that have a significant impact on the production of biofuel. The variance within and between data groups was determined using the analysis of variance (ANOVA) table. The ANOVA table shows how much of the response variable's variation (biofuel production) can be explained by the independent variables (A, B, C, D, E, AB, AC, AD, AE, and BJ) and how much is caused by random error. The ANOVA table comprises of three primary parts: the F-statistic, the p-value, the df, the mean square (MS), the source of variation, and the sum of squares (SS). The wellspring of variety alludes to the beginning of the information variety, which can be either the lingering or the model. The amount of squares estimates the information's changeability, with the absolute amount of squares addressing the amount of the squared deviations of the genuine qualities from the mean worth. The residual is the sum of the squared deviations from the predicted values of the actual values, while the model's sum of squares is the sum of the squared deviations from the mean of the predicted values. The model has 10 degrees of freedom (the number of independent variables) and the residual has 4 degrees of freedom (the number of observations minus the number of independent variables). These degrees of freedom represent the number of independent pieces of information used to estimate a parameter. The mean square, which indicates the typical amount of variation for each variation source, is calculated by dividing the sum of squares by the degrees of freedom. The degree to which the model explains the variation in the data is indicated by the F-statistic, which is the ratio of the model's mean square to the residual's mean square. The probability of obtaining an F-statistic that is as large as the one observed if the null hypothesis is true is represented by the p-value. The independent variables' insignificant impact on biofuel production is the null hypothesis in this instance. The model's p-esteem in this study is under 0.05, demonstrating that the free factors essentially affect biofuel creation and that the model is genuinely huge. In addition, the model is significant because the F-statistic is relatively large in comparison to the F-distribution for the 10 and 4 degrees of freedom, respectively. The estimated coefficients for the linear regression model used to investigate the production of biofuel from citrus peel can be found in the ANOVA coefficients table. The table provides a list of the intercept and independent variables' coefficients, standard errors, t-values, and p-values. When all of the independent variables are zero, the intercept has a coefficient of 0.0672, indicating the estimated value of the response variable.
