These factories face enormous problems with the overconsumption of acid during skim coagulation, which results to extra expenses and high acidic waste water production problems. Therefore the is a need to reduce the overconsumption of acid during skim coagulation. In order to solve this problem we started by identifying all possible causes of acid overconsumption at the factory using the ISHIKAWA diagram. We further hierarchized these causes using a Pareto diagram and sought out 3 main causes of great impact to be addressed which are: the low performance of the deammoniation process; poor practice of coagulation; negligence. We proposed solutions by optimising the deammoniation process at the tower i.e. controlling its skim and air flow rate inside the deammoniation tower to optimal values. Also we determine the optimal volume of acid needed for effective coagulation which when applied reduces acid consumption. Lastly we optimized by proposing a new mode of operations for the coagulation process. By implementing this new approach, we recorded an estimated total acid reduction of 28,924 L/month (347088L/ year) and this will enable the company to save money about 770,469 FCFA/month (21,245,639 FCFA/year). This approach can be adapted in any other rubber processing unit and will reduce acid overconsumption during skim latex coagulation.</p> Louden Motina Ambe Rex Copyright (c) 2021 American Scientific Research Journal for Engineering, Technology, and Sciences (ASRJETS) 2021-06-13 2021-06-13 80 1 1 16 Is the Study of Social Culture Making a Difference in the Implementation of Business Strategy in International Organizations? - A Bibliometric Analysis <p>The search for results and its interface with culture, with the adaptation to the transition of customs and technological innovations generate impacts on social factors. The diversity of cultures in work occupations and their association with group culture is a gap to be observed. As a result of this trend, it was observed the need to understand the studies carried out within a chronological approach, which brought the need to perform a bibliometric analysis. The purpose of this paper is to demonstrate the scenario of research carried out to understand the transition of culture within the strategic decision-making processes in multinational companies and its deployment through the projects in the different layers of these organizations due to the changes brought by technological advances as in special connectivity in the last 30 years referenced in the creation of the World Wide Web. For this purpose, bibliometrics was made with the keywords “Cultur*” and Boolean intersections “AND” for “business strateg*” OR “project portfolio management” OR "multinational compan*" consolidated into two different research bases. Through tools of analysis by specific statistical software can be highlighted as the main research outputs: the search for the subject and the importance of the theme, the focus on obtaining financial return based on performance; the base concentration on research with more than 20 years of publication linked to the companies' difficulty in the interaction of Culture with the transition of generations associated with customs and new technology; the concentration of research in know-how countries linked to the top-down management approach; and the factors of interaction between the internal culture of the organization and the local cultures of the groups in the countries of operation of these companies with the association of a top-down management communication line.</p> Edson Souza de Alencar Milton Vieira Junior Maria Júlia Xavier Belém Copyright (c) 2021 American Scientific Research Journal for Engineering, Technology, and Sciences (ASRJETS) 2021-06-13 2021-06-13 80 1 17 33 Investigating the Impact of Non-Hydrodynamically Connected Descaling Parameters in the Removal of Different Stages of Paraffin Deposits Using Multiple Nozzles in Petroleum Production Tubing <p>Despite the continued research efforts in understanding the erosional behaviors of multiple flat fan nozzles in the removal of different types of scale deposits from petroleum production tubing. The non-hydrodynamically connected descaling parameters such as stand-off distance, nozzle arrangement and chamber pressure have not been duly considered up to date. This research utilizes 3-flat fan high-pressure nozzles at a high injection pressure of 10 MPa to remove paraffin deposits at different growth stages from petroleum production tubing to evaluate the effects of the descaling parameters on scale removal. A stand-off distance of 25 mm, 50 mm and 75 mm; nozzle arrangement in novel orientations (triangle, diagonal &amp; right-angle) involving 7-nozzles header and chamber pressures (in compression – 0.2 MPa and vacuum -8.0 x10-3 MPa) were utilized as the varying non-hydrodynamically connected parameters. Generally, the selection of both nozzle arrangement and chamber air concentration was found to be governed by the type and shape of the deposit in question while the scale removal capability was found to be reduced with an increase in stand-off distance due to poor jet contact. An average hollow shaped paraffin removal of 276 g, 259 g and 226 g were recorded at ambient condition across the respective stand-off distance of the three respective nozzles arrangements. While the introduction of 0.2 MPa compressed air significantly increased the respective removal of the early stage paraffin deposition to 342 g, 299 g and 277 g respectively. Also, more hollow shaped removal improvement of 366 g, 320 g and 288 g were achieved after suctioning the chamber by -0.008 MPa, while simultaneously pumping water at 10 MPa. The case of solid shaped paraffin signifying complete tubing blockage was not effective at ambient condition, with average paraffin removal of 99 g, 126 g and 112 g respectively. However, the introduction of compressed chamber air registered the best solid paraffin removal results of 235 g, 286 g and 256 g respectively. Whereas the suction operation recorded an average removal of 229 g, 270 g and 250 g of paraffin across the respective jet positions and nozzle configurations. This result provides a practical approach to the removal of organic scales deposits at varying descaling conditions of injection pressure, standoff distance and nozzle arrangement.</p> Kabir. H.
