Dynamic models for start-up operations of batch distillation columns with experimental validation [PDF]

open access: yes, 2004
The simulation of batch distillation columns during start-up operations is a very challenging modelling problem because of the complex dynamic behaviour. Only few rigorous models for distillation columns start-up are available in literature and generally

Determination of polybutylene terephthalate polycondensation equilibrium constant using a batch reactor [PDF]

open access: yesMacromolecular Symposia, 2004
AbstractThe PBT polycondensation equilibrium constant at 255°C was determined using a batch reactor. Starting from a Polybutylene terephthalate (PBT) prepolymer having a degree of polymerisation of 12.7, equilibrium experiments were performed in the range of 1 to 50 mbar.

Remoção de níquel de soluções aquosas em batelada e em coluna utilizando a alga marinha marrom Sargassum filipendula - DOI: 10.4025/actascitechnol.v29i2.695

open access: yesActa Scientiarum: Technology, 2008
The nickel(II) biosorption capacity of the Sargassum filipendula brown marine algae was studied in the batch mode. The biosorption study involved the determination of equilibrium data of the nickel-biomass system, considering the influence of the ...

Learning backward induction: a neural network agent approach [PDF]

open access: yes, 2009
This paper addresses the question of whether neural networks (NNs), a realistic cognitive model of human information processing, can learn to backward induce in a two-stage game with a unique subgame-perfect Nash equilibrium.

The Significance of Multiple Saturation Points in the Context of Polybaric Near-fractional Melting [PDF]

open access: yes, 2004
Experimental petrologists have successfully located basaltic liquid compositions parental to mid-ocean ridge basalt that are, within experimental resolution, multiply saturated with three-phase harzburgite or four-phase lherzolite assemblages on their ...

Equilibrium and Kinetic Mechanisms of Fluoride Ions Adsorption onto Activated Alumina

open access: yesChemical Engineering Transactions, 2017
In this work, the fluoride adsorption by activated alumina (AAD) was evaluated in batch system. The point of zero charge of adsorbent was obtained. The effects of pH (2 to 12), temperature (30, 40 and 50 °C) and agitation (70, 100, 130 and 160 rpm) in ...
