Globally optimal basic design of multiple-unit heat exchangers Miguel J. Bagajewicz, Andre L. M. Nahes, Eduardo M. Queiroz, Diego G. Oliva, Javier A. Francesconi, et al. Aiche Journal, 2025 A novel approach (Complete Set Trimming) to address the globally optimal design of multiple‐unit heat exchangers (Shell and Tube, Double Pipe, Plate, etc.) is presented. Three arrangements: Series, Parallel, Series–Parallel, and Parallel–Series, for minimizing area, CAPEX, or total annualized cost are considered. The geometry of all (equal) units is determined together with the number of units and the fluid allocation. The article illustrates the need to minimize CAPEX explicitly instead of using the minimization of Area as its proxy objective function. In addition, the influence of available pressure drop in the final optimal design is also discussed. Finally, the article shows that solutions obtained by minimizing the Total Annualized Cost (TAC) render different solutions than those obtained by minimizing CAPEX, indicating that pumping costs matter, depending on the balance between operational and capital costs.
A Framework for Developing Semiquantitative Chemical Methods for Offshore Environments Using Smartphones H. V. P. Vieira, R. M.M. Barcellos, M. L. A. Gonçalves, R. Mesquita, M. A. G. Teixeira, et al. SPE Journal, 2025 Summary In oil and gas (O&G) offshore production units, specialized equipment and qualified analysts are not available. Therefore, simple and easy-to-implement chemical analysis methodologies are essential, making the digital image-based analytical methodology (DIBAM) a promising technique. However, in order for DIBAM to achieve satisfactory results, certain preliminary steps must be followed. In this paper, we share our knowledge on the key aspects required for the development of DIBAMs, including the selection of chemical methodologies, type of sample holder, image acquisition chamber, and, finally, image processing. We present a DIBAM developed following the proposed guidelines, demonstrating that a semiquantitative method can be achieved with a maximum error of 10%—a reasonable margin for the rapid resolution of offshore issues.

Water sources diagram and its applications Ewerton Emmanuel da Silva Calixto, Fernando Luiz Pellegrini Pessoa, Reinaldo Coelho Mirre, Flávio da Silva Francisco, Eduardo Mach Queiroz Processes, 2020 Water Sources Diagram (WSD) has proved to be one of the most efficient methods to reduce industrial freshwater consumption and to provide a minimum amount of wastewater to be treated. Different types of industry have been benefited from the use of this technique, which resulted in great savings in the design of the effluent treatment systems. Among the successful case studies, we mention herein applications in systems with wastewater treatment, thermal and water plants’ integration, oil refineries, petrochemicals, batch processes, pulp and paper plants, and textile plants. The degree of WSD maturity motivated researchers to not only improve WSD algorithms, but also extend the concept of the Sources Diagram to Source/Sink types of process. This paper presents a background of WSD progress as well as insights into future perspectives using the Sources Diagrams’ concept.
