The engineering of process plants in the chemical and pharmaceutical industry is a highly complex workflow where different disciplines work together from the recipe of the (chemical) substance that shall be produced, through process and automation engineering to commissioning and operation of the process plant. Especially the early phases of engineering are essential due to the various, indicatory decisions taken. This paper presents a systematic engineering approach for process plants in the early engineering phases based on the engineers’ intentions – the so-called intention-based engineering. The approach consists of three steps, starting from the formulation of intentions by using a controlled language, to the modelling of intentions by adding additional information such as dependencies, up to the design with intentions. The first and second step derive the intention model which represents the core of the intention-based engineering approach, while the last step focuses on the integration and usage of the intention model in the process plant engineering steps. The approach is evaluated using a 3-phase separator.
