Insulation is a forgotten technology that can provide an unrivaled return on investment. The Citrus Industry is not an exception. Insulation is the ‘Rodney Dangerfield’ of the construction industry: It receives very little respect and is taken for granted. Insulation is a powerful resource when designed, applied, and maintained properly. Yet, this technology is often forgotten or put on the bottom of the list and ignored. A recent survey conducted by the National Insulation Association of more than 160 industrial plants, manufacturing, engineering, and architectural firms found that: • Most had no idea of the payback period, rate of return, with the use of insulation, nor a method to quantify costs versus savings • Many acknowledged that numerous areas of insulation were in serious need of repair • The majority did not understand that insulation had any real environmental “tie in” • Some did not consider additional insulation necessary: “the plant is working fine” • Many could not relate corrosion under insulation to having anything to do with the insulation • Most acknowledged their specifications were outdated • Many confirmed they did not have a dedicated job function to address insulation specifications or anyone who was the “insulation champion” • Many did not think of insulation as a system or requiring any special design review or technical consideration That survey confirmed the ‘Rodney Dangerfield’ characterization and formed the basis for the foundation of a major industry educational and awareness initiative. The benefits of insulation are in many cases invisible and long lasting. This technology is not some mysterious myth. Possibly it is misunderstood and under appreciated due to lack of knowledge. Calculating the operational benefits and the return on investment can be relatively simple. However, an insulation system does not have any moving parts, computer chips, or fancy gauges, and it is certainly not sexy. Maybe that is why in many circles insulation is not an exciting topic of discussion, even though it is a time tested and proven technology that can often provide an annual return on investment greater than 100%. There has not been a more important time in recent history than now to think about insulation differently. The Citrus Industry is not immune to that thought process. Paper published with permission.

Abstract With the collapse of the Eastern block, once Egypt’s major industry supplier for machinery and spare parts, and the lack of skilled manpower, the Egyptian industry is finding it difficult to maintain its machinery and industrial base and to compete with the much more sophisticated and coordinated industries abroad. The cutoff of supply of maintenance parts from the Eastern Block, prompt the use of modern reverse engineering (RE) methods in the capturing the geometrical configuration and fabrication of rare maintenance parts, in support of the Egyptian Industry. This paper demonstrates, as a proof of concept, the use of the technology of RE in the fabrication of parts. The success of the experiment initiated a much wider application to the technology, that of patterns making in support of the casting industry. This will provide an accurate and expeditious means to properly maintain industrial plants and produce compatible spare pails urgently needed.

Building Information

Purpose The purpose of this study is to identify and analyse the key measurable returning factors, value drivers and strategic benefits associated with building information modelling (BIM) return on investment (ROI). The findings of this study provide researchers and practitioners with up-to-date information in formulating appropriate strategies to quantify the monetary value of BIM. The suggested research agenda provided would also advance what is presently a limited body of knowledge relating to the evaluation of BIM ROI. Design/methodology/approach To fill the identified gap, this study develops a comprehensive systematic review of mainstream studies on factors affecting BIM ROI published from 2000 to 2020. A total of 23 academic records from different sources such as journals, conference proceedings, dissertation and PhD theses were identified and thoroughly reviewed. Findings The reported BIM ROI ranged greatly from −83.3% to 39,900%. A total of 5 returning factors, namely, schedule reduction and compliance, productivity improvement, request for information reduction, rework reduction and change orders reduction were identified as the most commonly reported factors that influence BIM ROI. Four quantification techniques including general assumptions-based theoretical model, perceived BIM ROI based on survey, factors affecting BIM ROI with no reported ROI and quantified BIM ROI based on a case study were observed and pointed out in the review, together with their limitations. Finally, three major gaps were raised as the lack of consideration on the likelihood of BIM assisting in a construction project, intangible returning factors influencing BIM-based projects and industry standards in benchmarking BIM ROI. Practical implications The outcomes of this study would assist practitioners by providing the current evaluation techniques that address the limitations with BIM investment and present issues relating to the economic evaluation of BIM in the construction industry. It is also expected that presenting a deeper and wider perspective of the research work performed until now will direct a more focussed approach on productivity improvement efforts in the construction industry. Originality/value This study identifies and analyses the key measurable returning factors, value drivers and strategic benefits associated with BIM ROI on an industry scale rather than a particular organisation or a project scale.

Infrastructure is one of the favorite projects of every developed and developing nation. Construction industry occupies a prominent place in the infrastructure development of a country. Cement is one the elementary material components in the construction industry. Saudi Arabia has shown a weaker performance in generation of revenue over a period of five years from 2015 to 2019. In a situation of economic slowdown it becomes a challenge for the business concerns to maintain their profitability. The present study is designed to analyze and compare the profitability position of cement companies in the kingdom of Saudi Arabia during this period. The study belongs to top five cement companies in terms of market value and revenue generation in the kingdom of Saudi Arabia. To measure the profitability gross profit ratio, operating ratio, operating profit ratio, net profit ratio and return on investment have been used as variables. One way anova has been used to test the hypotheses. The study shows that these companies do not differ significantly from one another in terms of gross profit, operating profit and net profit but they differ significantly when return on investment is compared. Cement companies can increase their profitability by improving the components of those ratios that have been the cause of decline in profitability.

Since the word “cogeneration” was coined in President Carter’s energy message to Congress in April 1977, most articles covering the topic have dealt with defining its meaning, estimating the quantity of recoverable waste heat energy in various industrial segments, and describing the many drawbacks, i. e., federal energy policy, electric utility rate structures, tax credits, etc. associated with major industrial-utility co-operative power generation concepts. So much emphasis has been placed on the problems of large scale cogeneration projects that many operating industrial plants either lose sight of the potential benefits obtained by generating their own electrical power or shy away from the subject altogether.

Abstract Corrosion Under Insulation (CUI) continues to be an issue in many oil, gas and petrochemical installations. This paper builds on previous work to examine why the industry has struggled to come up with reliable and cost-effective solutions to the CUI problem. The limitations of different multidiscipline innovations are discussed together with positive examples of the latest promising industry projects and research, including risk management guidance, improved coatings, insulation system materials and design, non-destructive screening techniques and permanently embedded monitors. Key learnings from this review demonstrate the importance of better use of industry plant data to achieve improvements in managing CUI in all innovation disciplines.

Man-made deposits of fly ash (FA)—a solid by-product of coal combustion—accompany practically every thermal power station and many industrial plants. The total annual production of FA worldwide is about seven–eight hundred million tons, of which less than one third is recycled. The accumulated FA has become a problem for the environment due to its heavy metal content, which can be leached out. The mineral composition of FA is mainly represented by the glass phase and also by quartz, mullite, magnetite and other minerals. In the last decade, intensive studies have been carried out on the use of FA for the preparation of geopolymer materials. Due to their energy savings, environmentally friendly processing and high physical-mechanical properties, geopolymers are gaining attention in the construction industry as a potential replacement for Portland cement. In this work, we focused on the effect of natural dolomite addition to FA and mechanical activation of this blend on the geopolymerization process. The influence of dolomite dosage and duration of mechanical activation in a planetary mill on the reactivity of the blend in relation to NaOH solution and on the geopolymer compressive strength was studied.

Corrosion Under Insulation

In Japan, the deterioration of industrial plants built during the period of high economic growth in the middle of the 20th century has recently become a social concern. Corrosion under insulation (CUI) of piping in such plants is a pressing problem. X-ray and ultrasound inspections are conventional methods for detecting CUI; however, these methods are time-consuming and expensive. Therefore, rapid and low-cost screening techniques for CUI are required. We develop a hammering-type inspection robot system that moves inside the piping and records hammering sounds. Furthermore, we propose an acoustic analysis method to identify anomalous parts from the hammering sound using machine learning techniques. Using three testing pipes, we can successfully identify anomalous parts through acoustic analysis using a deep neural network as a supervised learning method. However, in practical piping inspections, the detection of anomalies without training data is required for further applications. Therefore, we investigate unsupervised learning anomaly detection using an autoencoder and a variational autoencoder and report the results.
