We are pleased to inform you that Petroleum-Gas University of Ploiesti, Romania is organizing the 6th International Symposium on Process Control (SPC), between 1st and 3rd of June 2009, at the Automatic Control and Computers Department, under the egida of the Romanian Society of Control Engineering and Technical Informatics (SRAIT). We kindly invite you to submit and present your latest research work and results in the symposium topics: - Artificial

A dynamic reactive distillation (RD) column model is developed for highly nonideal systems with potential phase splitting. Dynamic simulations and non-linear dynamic analysis are performed for recovery of acetic acid from waste waters by esterification with n-butanol, which is an interesting alternative to nonreactive separation processes. Two alternative RD column designs were tested with respect to their open loop transient responses to process

This paper addresses an industrially important problem of acetic acid recovery from a waste water stream via reactive distillation. The presence of a three-phase regime on the column stages due to a liquid liquid phase split between aqueous and organic phases is a typical characteristic of this process. A modern modeling approach is presented to detect the existence of potential phase splitting in this column. A good agreement of a phase splitting

A theoretical study of reactive distillation processes to remove acetic acid from its 30 wt% aqueous solution by esterification with n-butanol is presented. Two different column structures were identified, rendering theoretically close to 100% conversion of acetic acid. A model capable of precisely predicting the potential phase splitting is used. Total costs for the new processes are estimated and compared with estimated costs of nonreactive separation

The dynamic simulation of a crude oil unit is useful in understanding the unusual behavior of such a complex plant, which is induced by the dynamics of individual sub-processes in combination with the complex plant topology. Also, it serves to investigate suitable strategies for process control, including closed-loop operation at the nominal operating point, load and specification changes, as well as startup procedures. The model presented in the

A crude oil plant consists of a main column with several sidestripers and pumparounds. While steady state modeling and simulation is fairly standard today, using well-known software tools as HYSYS platform (ASPEN) and PRO/II environment (Simulation Sciences Inc.), only little is known about the dynamic simulation of crude oil plants intimacy in the open literature. Due to the process complexity, the references in this field mention many difficulties
