Hydrogen recovery from the purge stream of a cyclohexane production process using a mass exchange heuristic
(Pergamon-Elsevier Science Ltd, 2014-12)
In this paper, we propose a novel hydrogen recovery structure in a cyclohexane production process, arrived at by following a mass exchange heuristic developed in previous works [1,2]. In the cyclohexane production process ...
Behavior comparison for biomass observers in batch processes
(John Wiley & Sons Inc, 2014-01)
On-line estimation of biomass concentration in batch biotechnological processes is an active area of research because normally, the biomass is the desired process product output, and also because it is necessary for control ...
Optimal Design of Stable Processes
(Planta Piloto de Ingeniería Química, 2003-05)
Open loop dynamic stability is a major feature of operability. An optimization approach for open loop stable process design is presented. It is based on Lyapunov’s stability theory and formulated as an eigenvalue optimization ...
Process intensification through the use of multifunctional reactors for PEMFC grade hydrogen production: Process design and simulation
(Elsevier Science Sa, 2020-01)
A highly integrated process aiming electrical and heating power supply is proposed. Ethanol, water and air at atmospheric conditions are considered as feedstocks. Main focus is put in process intensification through the ...
Strategies for the simultaneous optimization of the structure and the process variables of a protein production plant
(Pergamon-Elsevier Science Ltd, 2000-10)
Process performance models for a multiproduct batch protein plant are used to exploit alternative strategies in the optimization of both the process variables and the structure of the plant. Simple process performance ...
Strain engineering and process optimization for enhancing the production of a thermostable steryl glucosidase in Escherichia coli
(Springer Heidelberg, 2017-01)
Biodiesels produced from transesterification of vegetable oils have a major problem in quality due to the presence of precipitates, which are mostly composed of steryl glucosides (SGs). We have recently described an enzymatic ...
Equivalent Markov processes under gauge group
(American Physical Society, 2015-11)
We have studied Markov processes on denumerable state space and continuous time. We found that all these processes are connected via gauge transformations. We have used this result before as a method for resolution of ...
A new dual modifier-adaptation approach for iterative process optimization with inaccurate models
(Pergamon-Elsevier Science Ltd, 2013-12-05)
In order to deal with plant-model mismatch, iterative process optimization schemes use some adaptation strategy based on measurements. The modifier-adaptation approach consists in performing first-order corrections of the ...
Heterogeneous photo-Fenton process mediated by Sn-substituted goethites with altered OH-surface density
(Elsevier Science SA, 2019-08)
Heterogeneous photo-Fenton process using several pure- and Sn-incorporated goethites was investigated for the decolourisation of methyl orange (MO). The used goethites presented a partial Sn(IV)-for-Fe(III)substitution. ...
