Unfortunately, since the beginning of petroleum exploration and production in Nigeria, the country has lost it numerous agricultural potentials, due to the immediate monetary benefits from exporting crude oil to the Europe and America. Since 2017, the Netherlands has repositioned herself as the second-largest exporter of agriculture in the world with a net value of $111 billion US. These include $10 billion of flowers and $7.4 billion of vegetables. The Netherlands is the world’s second-largest agricultural exporter, after the United States. In 2021, the net value of the agricultural export was more than $118 billion US. Nigeria must take a leave from Netherlands by setting a robust and sustainable policies, the Netherlands model, to salvage her agricultural developments that will catapult the country to be in the fore-front of the world agricultural products for both domestic and foreign export gains, which in-turn increases the nations’ gross domestic product, GDP.

It also reveals the incentive for flare reduction while encouraging domestic consumption of Liquefied Petroleum Gas (LPG) and the use of Compressed Natural Gas (CNG) for electricity generation. The simulation of the plant was done using ASPEN HYSYS version 11.0 with the Peng Robinson equation of state as the thermodynamic fluid package. The gas was gathered from two flow stations 0.8km and 6.4km respectively from the proposed processing field. Since the gases from the region under study is a sweet with negligible sulphur content there was no need for a sweetening process. The Tri-Ethylene Glycol (TEG) was used for the gas dehydration, then fractionators were simulated to produce LPG and CNG of high purity. Results from the HYSYS report shows good energy and mass balance as well as efficient gas flow throughout the processing cycle. The resulting volume of CNG and LPG is substantial to power several households and supply them with cooking gas respectively.\u0000Keywords: Natural Gas Simulation, Liquefied Petroleum Gas, Compressed Natural Gas, Computer aided Design.","PeriodicalId":416590,"journal":{"name":"September 2022 Special Edition","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134254450","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}

During deep-frying, the oil is exposed to elevated temperatures in the presence of air and moisture. A number of chemical reactions, including oxidation and hydrolysis, occur during this time, as do changes due to thermal decomposition. The oil commonly used in deep-frying includes groundnut oil, canola oil, sunflower oil, palm olefin, soybean oil. The addition of antioxidants is the most commonly used form to retard lipid oxidation processes and extend the shelf life of oils and fats. Synthetic antioxidants such as BHT, BHA, TBHQ and PQ are reported to be health hazardous, and some are removed from the GRAS (generally recognized as safe) list and banned in many countries. Natural antioxidants are mainly polyphenolic compounds that help to stabilize oils and food, trapping free radicals and retarding oxidative processes. Garlic (Allium sativum L.) is known to contain natural antioxidants that can remove reactive oxygen species (ROS) and reduce lipid peroxides and low-density lipoprotein oxidation. The antioxidant properties of garlic compounds are allyl cysteine, alliin, allicin, and allyl disulfide. This study was conducted to determine the effect of garlic on some quality characteristics of repeatedly used groundnut oil. The initial phenolic content of the oil before frying was 677±2.83g GAE/g. At the end of the frying period, the total mean value for the phenolic content of the samples were 493±7.53g GAE/g, 407±3.43g GAE/g, and 346±4.44g GAE/g for Sample GS2 (7% garlic), Sample GS1 (4% garlic) and Sample GS0 (untreated groundnut oil) respectively.

The concern by developed economies for climate change and alternative sources through the energy mix has fueled aggressive efforts to reduce global consumption of fossil fuels leading to divestment by major industry players like Royal Dutch Shell. Therefore, the PIA represents Nigeria's effort to acknowledge the changing environment. The petroleum industry adopted a change management approach to effectively harness the act's potential. Using a literature review, the study aims to assess the critical success factors for adopting change management of the petroleum industry stakeholders to implement the transition program. Using the theoretical lens of complex systems theory to assess change management. These complexities make the oil and gas industry environment somewhat disorganized and complex. When complexity occurs, we need tools and concepts to redirect attention and energy efficiently. The study posits that when accessing the critical success factors of the transition program f the PIA, It is essential that NNPC Ltd leaders publicly show commitment to the change to send a powerful message to external stakeholders about the seriousness of implementing the change. The study further recommends changing the work processes to reduce costs, optimize the performance of its industrial base assets and improve its environmental footprint. Access to technology by stakeholders enables the integration of the change process at speed.\u0000Keywords: change management; change implementation; critical success factor; organizational change; Petroleum Industry","PeriodicalId":416590,"journal":{"name":"September 2022 Special Edition","volume":"70 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115144261","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 initial moisture content of banana peel is about 70%, which leads to deterioration and limits the efficiency of conversion processes. Solar energy is abundant, free and renewable, so the solar drying of banana peel was investigated. Drying kinetics of banana peel in passive and active solar dryers were compared with that of direct sunlight. Mathematical and artificial neural network (ANN) modelling methods were applied to describe the rate of drying of the peel. The banana peel dried fastest in the active dryer followed by the passive dryer, then direct sunlight. The peels dried in the falling rate period. The Verma, Midilli-Kucuk and Weibull models best described the peel drying kinetics in direct sunlight, passive and active solar dryers, respectively. Feed-forward multilayer perception ANNs having (4-3-1) network topologies best fitted the drying data. The estimated diffusivities of moisture in the peel were 7.835 × 10-11, 9.59 × 10-11 and 1.952 × 10-10 m2 s-1 during its drying in direct sunlight, passive and active solar dryers, respectively.
