One of the clusters of the scientific school of the academician Viktor Kafarov is the direction created by us - cybernetics of chemical and technological processes in the industry of chemical reagents and high purity substances. For 40 years this direction was developed in the Institute of chemical reagents and high purity substances, and in recent years in the Science centre "Low-tonnage chemistry" Works were conducted in the following 4 directions: modelling and optimization of processes for production of chemical reagents and high purity substances (HPS); system analysis in technology of HPS and synthesis of the optimal individual and flexible multi-assortment manufacturing; creation of automated systems of scientific researches and technological processes control systems; development of automated databases, expert systems of the artificial intelligence and computer systems for making of the decisions. In the 2000-s, we have taken the leading positions in the chemical complex of Russia for development and implementation of information CALS-technologies - ISO 10303 STEP (Klemeš, 2010). Based on them there were developed the automated systems of design documentation in the technology of high purity substances, biotechnology (Bessarabov et al., 2010); plasma-cryogenic technology for obtaining of nanodispersed powders etc. (Bessarabov et al., 2013) CALS systems of computer quality management for the technology of high purity substances and nanomaterials were developed (Bessarabov et al., 2011b). In recent years, during the development of strategy of development of the chemical industry information technologies for the system analysis and rating estimation of innovative potential of 83 leading joint-stock and state ownership R&D organizations were developed for the Ministry of industry of Russian Federation. Also the system analysis of the innovation resources of 165 leading industrial enterprises of chemical and petrochemical complex was carried out.. Copyright © 2014, AIDIC Servizi S.r.l.

Rectification (distillation), absorption, crystallization, ion exchange, etc., are the preferred methods for fine cleaning. The main element of the distillation module is the packed rectifying column presented by a 1000 mm high shell with a diameter of 100 mm and made of fluoroplastic-4 flanging. The main application of the absorption module is to remove gas and other difficult to separate impurities from gaseous raw material (hydrogen chloride and hydrogen fluoride) due to redistribution these impurities between liquid and gaseous phases proportionally to their fractional pressure with receiving strong acids and their further desorption. The accessories of the module include container for absorbing liquid, overflow devices, filter for gas and finished product, sanitary heat-exchanger and heat-exchanger and cooler. When designing the absortion and distillation module, efforts are made to ensure process efficiency and to fulfill the requirements on manufacturability for components, units, and the whole installation. This is an abstract of a paper presented at the CHISA 2012 - 20th International Congress of Chemical and Process Engineering and PRES 2012 - 15th Conference PRES (Prague, Czech Republic 8/25-29/2012).

High purity nanomaterials (silicon, tungsten carbide, oxides of silicon, tin, iron, titan) are widely used in the innovative and science-intensive fields of economy. In manufacture of these substances it is exceedingly important that a by-product of synthesis should not contaminate the target products or interact with process equipment. Otherwise it will take up an additional amount of impurities. A promising way to tackle with this problem is application of low-temperature plasma. It allows to create a set of modern apparatus with the minimum microimpurity background. The advantage of this technique is that it can yield nanodispersed powders which is virtually impossible with other high purity technologies. It is known that plasma allows receiving a various level of structural conditions. But difficulties of realization of the given conditions always rested against necessity of their instant fixing. However, it is possible only in cryogenic jets of hydrogen, nitrogen, oxygen, argon, helium, etc. Reactors used earlier had a lack of this possibility. Creation of a new class for cryogenic plasmachemical technologies for obtaining of the high purity nanomaterials was the purpose of the given work. During the researches there was examined the influence of the following 3 factors for the dispersion of the final product: The aggregate state of the original substance, the components ratio (heads of high-speed plasma jet and jet injected gas) and the speed of cryogenic tempering. Development of cryogenic plasmachemical nanotechnologies was spent on the basis of the CALS-technologies (Continuous Acquisition and Life cycle Support). Copyright © 2013, AIDIC Servizi S.r.l.
