Introduction: In the pedagogical treatment of interdisciplinarity in Cuba, important actions are carried out as part of the continuous transformation process of the educational system. In the present investigation, the knowledge systems of the subjects with the greatest contribution to process safety are identified. Objective: To analyze the interdisciplinary methodological activity in the Chemical Engineering career in terms of process safety for its articulation with national security and defense. Materials and Methods: The analysis is carried out based on Study Plan E, Preparation for Defense discipline program, disciplines programs of the Chemical Engineering career and documents issued by the Ministries of Higher Education and the Revolutionary Armed Forces. A case study is presented. Results and Discussion: Hazards identification, vulnerability and disaster risks; potential damage and actions to eliminate and/or reduce the effects of events are essential components for identifying knowledge systems related to process safety and links to national security and defense. Conclusions: Methodological activity has led to define that the disciplines Process Engineering, Chemical and Biological Fundamentals, Fundamentals of Automation and Unit Operations and Processes are made up of subjects that articulate process safety with the subject of security and national defense of the discipline Preparation for Defense. The procedure and the general systematic approach for safe design contribute to consolidate the interdisciplinary link in the Plant Design subject. [ABSTRACT FROM AUTHOR]

Process Integration combine several processes to reduce consumption of resources and harmful emissions, becoming an important asset in ensuring the sustainability of industrial processes. This paper aims to set energy performance indicators of a cane sugar refinery. A procedure that includes the energy analysis and Pinch Analysis methodologies is applied, with the use of HENSAD. Targets and energy performance indicators, currently not reported for this refinery, contribute to the definition of an energy baseline and the systematic measurement of efficiency. There is an excess in thermal power duty of 32,5 MW with respect to the minimum heating duty, which determines the research into retrofit designs of the heat exchanger network. Annual savings of 1 010 571 USD estimated in energy analysis and heat integration make the evaluation of investment projects in the energy area feasible. [ABSTRACT FROM AUTHOR]

Introduction: The work presents the experiences in development to make possible the alternatives of production chain in environmentally compatible conditions, of the sugar cane company Heriberto Duquesne based on the concept of biorefinery and using the circular economy. Objective: To show an effective and improving path for training doctors who contribute with their research to strengthen the production chain of the company for its operation and development as a biorefinery so that its business volumes gradually grow. Materials and methods: The research is carried out by articulating the postgraduate activities of the company's professionals who are surpassed in postgraduate master's degrees and doctorates who act as coordinators of projects that bring together the actions of the master's degree and of professionals who are not incorporated into the master's degree courses in a project work system. Results and discussion: This action is a component of an anticipatory system of strategic management, whose mission is to contribute to learning the best way of sustainable development through increasing linkage with other sectors of the country's economic and social life. Conclusions: The work offers the possibility of contributing to the generation of knowledge for sustainable industrial development that favors economy, and also the social impact of the territories through the resuscitation of the batey of this company in the sugar cane industry.

Introduction: In this work, based on the necessary technological linkage that exists in a raw sugar factory with a nearby sugar refinery, a strategy is proposed to strengthen its material and energy linkage in its development, extracting the juice from the filters. Objective: To evaluate the impact of extracting the juice from the filters on the influence on the quality of raw sugar, determining the optimal percentage of extraction to achieve the energy linkage of the combined raw sugar factory, refinery and torula cream. Materials and methods: The effect of the extraction of the juice from the filters on the quality of this type of sugar, and with it on that of refined sugar, is evaluated through the statistical modeling of the process through the aggregation of the models of the component elements, considering variations of the models in the purification stage for different per hundreds of extraction. Results and discussion: The global models of the process obtained through the aggregation of models of the partial stages are effective for predicting the sugar quality parameters. The extraction of the juice from the filters significantly increases the amount of leftover bagasse in the production of raw sugar. Conclusions: The extraction of the juice from the filters benefits the quality parameters of the produced sugar and significantly increases the amount of excess bagasse in the production of raw sugar, being an alternative to contribute to other productive demands.
