Extractive distillation: recent advances in operation strategies
Extractive distillation is one of the efficient techniques for separating azeotropic and low-relativevolatility mixtures in various chemical industries. This paper first provides an overview of thermodynamic insight covering residue curve map analysis, the application of univolatility and unidistribution curves, and thermodynamic feasibility study. The pinch-point analysis method combining bifu...
متن کاملRecent advances in understanding blue copper proteins
The type 1 (T1) or blue Cu (BC) proteins are a highly studied group of electron transfer (ET) active sites in bioinorganic chemistry. In this review, we cover several more recent results which extend the understanding of the geometric and electronic structure of these interesting Cu ET sites. Spectroscopicmethods in tandemwithdensity functional theory (DFT) and timedependent-DFT (TD-DFT) calcul...
متن کاملRespiratory health of workers exposed to metal dusts and foundry fumes in a copper refinery.
OBJECTIVES To assess airflow limitation in workers exposed long term to metal dust, the prevalence of pleural plaques in those workers exposed in the past to asbestos, the influence of pleural plaques on lung function, and the possible association with airway disease caused by asbestos. METHODS A cross sectional and longitudinal (seven year) survey of 494 long term (mean (SEM) 21(1) years) wo...
متن کاملRecent studies of the copper-molybdenum antagonism.
The biological antagonism between copper and molybdenum was discovered when cattle grazing pastures high in Mo were found to develop a syndrome characterized by diarrhoea, growth retardation, anaemia and achromotrichia, which could be prevented by administering Cu. This syndrome was subsequently reproduced in non-ruminants, but further studies revealed important differences in the nature of the...
