Interfacial tensions and phase behavior of alcohol-hydrocarbon-water-sodium chloride systems
(1987)
The phase behavior and interfacial tensions of mixtures of alcohol, alkane, water, and sodium chloride that split into two or three liquid phases at 25°C are reported as a function of type of alcohol and alkane and sodium ...
APPLICATION OF MODEL PREDICTIVE CONTROL TO BATCH POLYMERIZATION REACTOR
The absence of a stable operational state in polymerization reactors that operates in batches is factor that determine the need of a special control system. In this study, advanced control methodology is implemented for ...
Challenges and opportunites for the chemicals industry in ArgentinaArgentina's Chemicals Industry: Challenges and Opportunites
(Amer Inst Chemical Engineers, 2014-02)
Boosted by domestic and international companies, Argentina’s chemicals industry continues to grow as demand for its products increases— even in the face of challenges posed by feedstock availability and the need for increased ...
Quality control of polymer products through spectral imaging and chemometrics methods
(2009)
Spectral imaging is increasingly used to develop rapid and non-invasive analytical sensors in a variety of fields. This paper discusses the ability of chemometrics methods, such as multivariate image analysis (MIA) and ...
Synthesis and characterization of polyacrylamide-chitosan hydrogels
(2007)
Polyacrylamide/chitosan hydrogels were synthesized in aqueous itaconic acid solution (1% w/w), in order to determine its swelling kinetics at various chitosan concentrations. Analysis of the hydrogel swelling behavior ...
