This paper analyzes the role of the Definite Integral in the training of chemical engineering students. The praxeologies in which the definite integral is involved are identified, both in the mathematical discipline and in the intermediate discipline with the profession. For this purpose, the textbooks of mathematics and specialty courses are analyzed, taking into account elements of the Anthropological Theory of Didactics. The notions of generator of a type of tasks (GT in spanish) and variables ($V_i$ in spanish) are used to identify the praxeologies as they allow to relate the specific and the generic. The praxeological models identified support the field of mathematical activity at stake. This makes explicit those technical and technological elements that should be emphasised when organising a course in integral calculus for chemical engineering students. In this way, the course will respond to activities in their professional environment.
