Batch Emulsion Polymerization of Vinyl Chloride: Effect of Operating Variables on Reactor Performance
(Planta Piloto de Ingeniería Química, 2001-12)
We analyze experimentally the effect of several operating conditions on conversion and molecular weight distributions of PVC obtained in batch emulsion polymerization. The operating variables studied were reaction temperature, ...
Application of dynamic optimization techniques for poly(b̃- hydroxybutyrate) production in a fed-batch bioreactor
(American Chemical Society, 2010-02)
Poly(b̃-hydroxybutyrate), PHB, is a microbial biopolymer produced by bacteria under unbalanced culture conditions. Such unbalanced conditions can be easily reached in a fed-batch bioreactor; therefore, it is important to ...
Nitrification and aerobic denitrification in anoxic-aerobic sequencing batch reactor
(Elsevier, 2016-01)
The aim of this study was to evaluate the feasibility of achieving nitrogen (N) removal using a lab-scale sequencing batch reactor (SBR) exposed to anoxic/aerobic (AN/OX) phases, focusing to achieve aerobic denitrification. ...
Suboptimal Control Strategies for Finite-Time Nonlinear Processes with Input Constraints
(Hindawi Publishing Corporation, 2013-09)
Novel techniques for the optimization and control of finite-time processes in real-time are pursued. These are developed in the framework of the Hamiltonian optimal control. Two methods are designed. The first one constructs ...
Batch process modeling for optimization using reinforcement learning
(Pergamon-Elsevier Science Ltd, 2000-07)
Imperfect and incomplete understanding of reaction kinetics compounded with uncontrollable variations not only prevent achieving an optimal operation of batch and semi-batch reactors, but also give rise to potential risks ...
Propoxylation of Fatty Amines: Switching from Batch to Flow
(AIChe, 2020-02)
The ethoxylation and propoxylation of fatty amines are important industrial reactions commonly performed in de‐intensified semi‐batch reactors. The present study aims to intensify these reactions by transferring the process ...
Reliable laboratory reactor data analysis: Evaluation of commercial FCC catalysts in a batch fluidized bed reactor
(Taylor & Francis, 2015-01)
Statistical techniques for the treatment and analysis of experimental data from laboratory reactors were considered, as applied to a CREC Riser Simulator reactor for the example of fluid catalytic cracking catalyst evaluation. ...
Aerobic degradation of ibuprofen in batch and continuous reactors by an indigenous bacterial community
(Taylor & Francis, 2016-10)
Water from six points from the Riachuelo-Matanza basin was analyzed in order to assess ibuprofen biodegradability. In four of them biodegradation of ibuprofen was proved and degrading bacterial communities were isolated. ...
Molecular Weight Distributions in Ideal Polymerization Reactors. An Introductory Review
(Planta Piloto de Ingeniería Química, 2011-10)
The ultimate aim of polymerization reaction engineering is the production of polymers with tailor-made properties. An introductory review into this field is presented, with emphasis on the effects on the molar mass ...
About the performance of Sphaerotilus natans to reduce hexavalent chromium in batch and continuous reactors
(Elsevier Science, 2009-09)
The hexavalent chromium biological reduction constitutes a safe and economical detoxification procedure of wastewaters containing Cr(VI). However, little research has been done to evaluate Cr(VI) tolerance and reduction ...
