In view of the growth of the industrial sector in the state of Ceará and the increasing demand for professionals who, in addition to technical expertise, also demonstrate behavioral skills, it becomes relevant to understand how the internship experience contributes to the development of essential competencies for professional practice. This study aims to analyze the influence of the curricular internship on the professional training of chemical engineering students, seeking to identify the main skills developed during this experience from the perspective of managers of companies located in Ceará. The research adopted an exploratory and descriptive approach. The exploratory stage was based on documentary analysis and scientific studies related to competency development in the engineering context. In the descriptive stage, an electronic questionnaire was applied to managers of companies in Ceará that host chemical engineering interns. The results indicate that the curricular internship contributes to the development of technical competencies, such as data interpretation and report preparation, performance of laboratory analyses, and mastery of productive processes. Regarding behavioral skills, problem-solving ability, sense of responsibility and autonomy, communication, and teamwork stand out. It is concluded that the internship plays a strategic role in the training of chemical engineers who are better prepared to meet market demands, strengthening employability and professional insertion in the industrial context of Ceará.

Understanding the formation and stability of these systems is of paramount importance for mitigating issues and optimizing production. Parameters associated with emulsion stability, such as the Droplet Size Distribution (DSD) and the mean droplet diameter, are fundamental for characterizing and understanding emulsion behavior. Traditional analysis methods, such as manual counting in micrographs, are labor-intensive, subjective, and poorly scalable. In this context, the present work developed a Python-based application capable of automating the processing of emulsion micrographs through the Hough Transform for circle detection, enabling the determination of the mean droplet diameter (D32) and the corresponding DSD. A total of 325 emulsions were produced using 13 distinct crude oils, with variations in temperature, salinity, and water cut; after filtering for immediate instability, 265 emulsions were analyzed. The implemented method presented an average absolute error of approximately 1.3 μm when compared to manual processing performed using the ImageJ software, while reducing processing time from approximately 30 minutes to less than 5 seconds per image set. The application also incorporated machine learning models to predict emulsion stability, viscosity, and D32, following the methodology proposed by Rolim et al. (2026). The use of Python programming enabled fast analyses, providing significant advances in standardization and in the handling of large volumes of experimental data.

This study demonstrates the application of continuous improvement methodologies and tools to reduce Can and Extract losses on a packaging shop floor at a local industry. Some of these methodologies are called Value Stream Mapping, Unified Problem Solving, Root Cause Failure Analysis and Kaizen Teams and they were applied with the help from the machine’s operators and their supervisors. Two Kaizen Teams were created, one with focus on Can loss and the other on the Extract loss, both following the same already defined steps and establishing quantified goals, as is already expected from a team of its nature. The root cause of every loss was investigated and corrective actions were established so these losses could be reduced as much as possible. After this, all the goals were achieved. In comparison with the previous measured period, the analyzed process reduced the average percentage of can losses from 1,02% to 0,36% and the average percentage of extract losses from 1,65% to 0,44% after the implemented actions.

However, to ensure its efficient use and meet the required purity specifications, it is essential to remove contaminant gases such as H₂S and CO₂, commonly found in streams from reserves like Brazil's Pre-Salt fields. In this context, metal-organic frameworks (MOFs) emerge as promising materials due to their high adsorption capacity, selectivity, and stability under harsh conditions. Among them, Mg-CUK-1 stands out as an environmentally friendly adsorbent with the rare ability to reversibly adsorb H₂S at low concentrations. This work investigates, through molecular simulations, the performance of this framework in the adsorption of H₂S and CO₂ at characteristic concentrations of Pre-Salt reservoirs, analyzing its selectivity under different operating conditions. The results reinforce the potential of Mg-CUK-1 as an innovative and sustainable solution for natural gas separation and purification, contributing to the development of more efficient technologies and enabling new production chains. This approach not only aims to meet Brazil's growing energy demands but also aligns with global climate mitigation goals and the transition to a cleaner energy matrix.
