Increase of productivity of process urgently requires application of more and technical advance.
As is known for deriving of isobutylene, being raw material at development of polyisobutylene and butyl rubbers widely use proces of dehydrogenation of isobutylene in pseudo-liquid catalyst bed, circulating in reactor-regenerative system. Opportunities of this process in the production conditions completely are not implemented because of reactor-regenerative (feed-heating) system in the non optimum condition that stipulated not by the account of agency of reaktionary medium and conditions of regeneration on activity of catalyst. To optimal support of process absence precludes with convenient and simple mathematical model of process and also a discretization of used analytical methods of the analysis of contact gas enough. Last hampers architecture of continuous analytical monitoring of indexs of process that precludes with creation of a computerized monitoring system and optimum control of process.
In the present operation results of development of method of continuous analytical monitoring of technological indexs of conversion and selectivity not astable process of dehydrogenation of isobutane on datas of a density and thermal conductivity of contact gas based on dynamic kinetic model of the reactor-regenerative block are given.
The abbreviated mathematical model of a commercial run of dehydrogenation of isobutane with the account not stationary activity of catlyst is generated. The given model has been applied for optimum control of process with the help designed on base line of a computer of computerized system.
As a result of application designed mathematical moel engineering both software accuracy and an operationability of monitoring of technological indexs of a commercial run of dehydrogenation of isobutane has raised that efficiently affected on the savings and upgrading of emitte products.
