PP-III-73PHYSICO-CHEMICAL AND TECHNOLOGICAL BASIS FOR COMPUTERFORECASTING AND OPTIMIZATION OF PETROCHEMICAL PROCESSESON Pt-CATALYSTSKravtsov A.V., Ivanchina E.D., Ivashkina E.N., Kostenko A.V., Gungazova M.S.Tomsk Polytechnic University, Tomsk, RussiaIndustriy company «Kirishinefteorgsintez», RussiaE-mail: ied@zmail.ruProposed approach to the development of kinetic models of reforming processesrepresents the sequence of stages of formation of the adequate scheme of mechanism ofchemical-technological process with its further kinetic description, on the basis of which nonstationarygeneralized model of catalytic reactors and of the whole chemical technologicalsystem is formed. This model allows not only to efficiently assess the optimal regimes ofprocesses for this raw material but also to forecast the catalyst activity during theintergeneration period and during its entire life time and to solve the problem of complexprocessing of crude oil at oil-processing plants and of modernization of active commercialplantsMethological aspects of intellectual systems (IS) formation and their usage forforecasting of petrochemical processes and for training of university students and plantengineering staff on questions connected with physical-chemical and technological laws ofindustrial processes are considered. The objective necessity of IS using while preparation ofengineers according to discontinuous and encyclopaedic principle is shown. The principles ofIS creation and realization on the base of generalization of industrial units operationexperience for special date processing in computer dialogue regime for users are expounded.Methods of forming of physical-chemical models of heterogenous catalytic processescounting catalyst deactivation are generalized (Fig. 1).The work sets new approach to the efficiency rising and optimization of commercialbenzine production by use of computer modelling based on physical-technical andtechnological peculiarities combined with the data obtained from the existing productionlines. Physical-chemical analyses with computer processing of experimental data fromrefineries offer solutions for the problems of catalyst tests varied due to peculiarities of rawmaterial and technological process, optimal level for Pt-contact of acid and metallic activity,technological parameters stabilisation and catalyst regeneration period forecasting.
