Instruments and Systems: Monitoring, Control, and Diagnostics Annotation << Back Virtual Modeling of the Analytical Laboratory of the Research and Production Complex of Fine Chemistry V.E. TROKHIN, D.A. GRISHAEVA, A.M. BESSARABOV, E.R. VISHNIKINA Work has been carried out to create a digital twin of the analytical laboratory of one of the leading research and production clusters of low-tonnage chemistry, which includes the industrial complex of JSC "ECOS-1" and the Research Center " Fine Chemicals". With the help of the Blender computer-aided design system, a virtual model of the analytical laboratory for chromatographic analysis has been created, including a 3D design model and databases on model elements. All the developed elements of the model are considered in four categories: appliances, electronics, equipment and furniture. Virtual models of two gas chromatographs "Chromatek-Crystal 5000" have been created for the category "Devices".2" and liquid chromatograph "LC-20 Prominence", as well as models of auxiliary analytical instruments: Fischer titrator "Expert-007"; concentrator "KN-2m"; scales "Practicum 224-1ORU". The resulting 3D model is used to create animations and simulate the internal work processes of an analytical laboratory. Keywords: digital twin, 3D model, fi ne chemistry, chemical reagents, especially pure substances, analytical laboratory, specialized equipment, analytical instruments.
