In this work, an algorithm was developed to determine different possibilities of distillation cuts support productivity and improve the final quality cachaça, a Brazilian spirit beverage. The process simulated using Aspen Plus® software, considering wide range fermented musts compositions available in literature obtained by fermentation with yeast strains. Twenty-four simulations were carried o...

Batch or semi-batch chemical reaction units often requires multiple operational phases to convert reactants valuable products. In various production facilities, the switching decision of such has be confirmed and registered by operating personnel. Imprecise can waste a significant amount time energy for unit, which gives negative plant sustainability costs. Additionally, automation phase is rar...

BACKGROUND This study investigates the generation of HCl and other acid gases from boiling calcium chloride dominated waters at atmospheric pressure, primarily using numerical modeling. The main focus of this investigation relates to the long-term geologic disposal of nuclear waste at Yucca Mountain, Nevada, where pore waters around waste-emplacement tunnels are expected to undergo boiling and ...

The article examines the geographical area delimited for production of Divine and specific characteristics physical-geographical conditions Călărași vineyard through prism different methods distillation wine distillates. Technological regimes distilling raw materials organoleptic physico-chemical indices such as: alcohol content, optical density, pH, aldehyde higher content volatile acid are sc...

The alternative fuel butanol can be produced via acetone-butanol-ethanol (ABE) fermentation from renewable resources, i.e. biomass. Expensive feedstocks and the high costs for the separation of ABE from the dilute fermentation broth in the downstream processing have so far prohibited the industrial-scale production of bio-butanol. The low productivities and butanol yields of ABE batch fermentat...

waste low density polyethylenes (ldpe) represent a source of energy and valuablechemicals, were pyrolysed catalytically in a batch reactor under atmospheric pressure. calciumcarbide was used as a catalyst to explore its effect on pyrolysis product distribution. the effect oftemperature, amount of catalyst and time on the yields of the pyrolysed products wasinvestigated. the effect of catalyst o...

Background: Ethyl lactate is an environmentally benign solvent, which could substitute petrol-based volatile organic compounds (VOCs) in many applications if production costs are reduced. It usually produced by the esterification of lactic acid with ethanol – two important chemical building blocks biorefineries that available at industrial scale. Reactive distillatio...
