Availability of quality power has become an important issue for industrial utilities due to frequent performance variations in process industries. Increase in the generating capacity has not kept up pace of power demand, which results into shortage of power supply and power system network is normally subjected to varying and unequal loads across the three phases. Continuous variation of single-phase loads on the power system network leads to voltage variation and unbalance, most importantly; the three-phase voltages tend to become asymmetrical in nature. Application of asymmetrical voltages to induction motor driven systems severely affects its working performance. This paper presents the effects of voltage variation and unbalance on the performance of an induction motor driven centrifugal pump with a case study.

Accident is one of the big issues that occur repeatedly in the process industries today though there is numerous application of the variety safeguarding measures that have been introduced. Equipment failure is identified as one of the root causes of these major accidents. One of the established standards that addressed the above issue is a Mechanical Integrity (MI) element of Process safety Management System (PSM) 29 CFR 1910.119(j). The main objective of this study is to introduce a systematic technique to implement PSM MI in process industries. This study covered analysis of requirements of the standard, development of framework and prototype tool as well as concept validation through a case study. Implementation of this technique will help employers to prevent major accidents and compliance to the PSM standard simultaneously.

Nineteenth-century world exhibitions were platforms to demonstrate technical and technological changes that witnessed the modernization and industrialization of the world. World exhibitions have contributed to the promotion of new inventions and the popularization of already known, as well as the emergence of art objects of world importance. One of the most important world events at the turn of the century was the 1900 World's Fair in Paris. Participation in the World's Fair was not the first experience of this kind of activity for sugar growers in the Russian Empire. Most of them were members of the Kyiv branch of the Russian Technical Society, which in turn took the most active part in the work of blighty and international industrial exhibitions, receiving high awards. The main sugar enterprises were concentrated on the territory of modern Ukraine in the possession of several large companies owned by Tereshchenko, Kharitonenko, Khanenko, Brodskyi, Simirenko, Yakhnenko and others. The Russian sugar industry occupied a prominent place at the World's Fair in Paris in 1900, as its share in world sugar production was 17%, and the area of beet crops, it was ahead of all other countries (in 1900 sugar beets were sown 548,796 hectares). The exposition testified to this powerful development of the industry. At the World's Fair in 1900, Russia's sugar industry was housed in the Palace of Agriculture and was represented in the pavilions by well-known sugar firms, such as the Department of Land (Timashiv Beet Sugar and Refinery), I. H. Kharitonenko and his son; brothers Lazar and Lev Izrailevich Brodskyi; O. N. Tereshchenko, heirs of F. A. Tereshchenko; the Tereshchenko brothers, the Botkin brothers (Novo-Tavolzhanskyi sugar factory); joint-stock companies of sugar and refineries: “Constance”, “Germanov”, “Gmina Lyshowiche”; E. A. Balasheva (Mariinskyi Sugar Plant of Kyiv Province), H. H. Balakhovski (Mariinskyi beet-sugar and refineries of the Kursk province). A characteristic feature of the sugar industry was that they mainly represented family businesses based on strong family ties, ethno-cultural and religious values. In addition, they intertwined the functions of owners and managers. Thus, the author tries to analyze the participation of representatives of the sugar industry in the World's Fair in 1900 and define the role of exhibitions as indicators of economic development, to show the importance and influence of private entrepreneurs, especially from Ukraine, on the sugar industry and international contacts.

In the process industries, it is rather uncommon for companies to develop new process technology or even to manufacture new process equipment. As a result, they are highly dependent upon various kinds of equipment suppliers in their effort to acquire new process equipment in order to improve their operating performance. Two previously presented theoretical frameworks for collaboration during the innovation and operations stages have been merged for use as a research instrument in a single case study on the collaboration between a mineral producing company and a supplier of technology and equipment. The evidence from this study shows that it is beneficial for collaborating partners to engage in upfront discussions of pros and cons before entering collaborations. Collaboration during the "innovation stage" was determined to be an interesting avenue to follow for both parties. The need for collaboration during the production stage seemed to be most important during the "start-up" and "optimisation and upgrading" phases. The combined frameworks have proven to be a powerful research instrument for studying the selected kind of collaboration.
