Intensification of the commercial run of deriving of isobutylene

چکیده
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 process of dehydrogenation of isobutylene in pseudoliquid catalyst bed, circulating in reactor-regenerative system. Opportunities of this process in the production conditions completely are not implemented because of reactor-regenerative (feedheating) system in the non optimum condition that stipulated not by the account of agency of reactionary 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 indexes 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 indexes of conversion and selectivity not astable process of dehydrogenation of isobutene on dates 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 isobutene with the account not stationary activity of catalyst 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.

Topanol A is a phenolic antioxidant additive, which is used in storage tanks for jet fuels produced in the petroleum refineries throughout the country. Topanol A mostly consists of 2,6-di-t-butylphenol. The conventional methods for the preparation of this compound involve ortho-alkylation of phenol using 2-methylpropene (isobutylene) as the alkylating agent. The compound has been prepared by or...
متن کاملThe External Determinants of Inflation: The Case of Iran
The study of determining the factors affecting inflation or consumer price index has been conducted by many macroeconomic economists nationally as well as internationally. In this paper, we assess the external determinants of inflation dynamics in Iran. For this purpose, we use an OLS single equation model and a vector error correction model (VECM). Results of the analysis reveal that money sup...
متن کاملA Novel, Low-Cost, Portable PID Sensor for Detection of VOC
A low cost portable photoionization (PID) sensor was successfully designed and manufactured. Unlike existing commercial PID sensors, our device provides two outputs, one associated with the total chemical components and a second that provides some level of compositional information. We believe that this makes this sensor system more useful than a standard PID, with a similar, if not lower, cost...

In this paper after a general literature review on the concept of Efficient Frontier (EF), an important inadequacy of the Variance based models for deriving EFs and the high necessity for applying another risk measure is exemplified. In this regard for this study the risk measure of Lower Partial Moment of the first order is decided to replace Variance. Because of the particular shape of the pr...
