Background. 3D modeling allows creating beter for students’ perception and understanding 3D models of apparatuses, as well as enabling the implementation of different placement variations of these models, which facilitates the task of developing projects of volume-planning decisions in the designing of complex chemical-technological schemes and will contribute to a deeper studying of chemical technologies of inorganic substances and processes of water purification.

Objective. The purpose of the paper is to create Blender 3D models of apparatuses and dilute nitric acid synthesis schemes, as an example of using this 3D environment for the studying of chemical-technological processes.

Methods. Computer modeling of chemical technology equipment on the example of dilute nitric acid production was applied.

Results. The simulating chemical technology objects’ main advantages in the Blender environment are considered on the example of created 3D model of the dilute nitric acid production shop. Using the design environment with built-in algorithmic language allows both automating the process of designing chemical production and carrying out constructive calculations of individual apparatus.

Conclusions. The use of 3D modeling techniques in designing improves the quality of both educational and real projects of the chemical technology industry. The learning process with using the real production 3D models creating can improve the quality of chemical engineers because, in the process of such modeling, elements of the scheme that are usually not reflected in plans and incisions (for example, pipelines) are considered. It is essential for the further professional activity of learning chemical engineers. The use of the Python language in Blender gives access to various libraries freely available for this programming environment.
