Oil extraction kinetics of hydrothermally pretreated canola seeds
(Wiley, 2015-05)
In this work the kinetics of oil extraction from spring canola seeds subjected to a hydrothermal pretreatment with direct steam (393 K, 5 min) was studied. The differences between the seed internal structure generated by ...
The hydrothermal alteration of the cordón de inacaliri volcanic complex in the framework of the hidden geothermal systems within the pabelloncito graben (Northern Chile)
(MDPI, 2021)
Detailed mineralogical analyses in areas with surface hydrothermal alteration zones associated with recent volcanism (< 1 Ma) in the Central Andean Volcanic Zone could provide key information to unravel the presence of ...
Asymmetrical structure, hydrothermal system and edifice stability: The case of Ubinas volcano, Peru, revealed by geophysical surveys
(Elsevier, 2014-04)
Ubinas volcano, the historically most active volcano in Peru straddles a low-relief high plateau and the flank of a steep valley. A multidisciplinary geophysical study has been performed to investigate the internal structure ...
The hydrothermal system associated with Miocene Chimpa volcano, Central Andes: Implications on potential mineralization
(Pergamon-Elsevier Science Ltd, 2020-11-02)
Miocene volcanism in the central sector of the Puna plateau, in the back–arc region of the Central Andes, has important economic potential, because it is associated with many epithermal ore deposits. Chimpa volcano is one ...
Groundwater age and hydrothermalism of confined aquifers in the Argentine Pampean plain
(SpringerOpen, 2017-12)
The Pampean plain of Cordoba province (Argentina) has hydrothermal manifestations linked to Cretaceous depocenters. However, they are in general neither well known nor carefully used, and, in numerous cases, they are ...
Optimization of Large-Scale Hydrothermal System Operation
(Asce-Amer Soc Civil EngineersReston, 2012)
Optimization of Large-Scale Hydrothermal System Operation
(ASCE-AMER SOC CIVIL ENGINEERSRESTON, 2012)
This paper presents the development of a mathematical model to optimize the management and operation of the Brazilian hydrothermal system. The system consists of a large set of individual hydropower plants and a set of ...
Application of the mineralogy and mineral chemistry of carbonates as a genetic tool in the hydrothermal environment
(MDPI, 2021)
The mineralogy and mineral chemistry of carbonates from various hydrothermal deposits, including volcanic-hosted Au-Cu epithermal, "Chilean Manto-type" Cu(-Ag), stratabound Mn, and Ag-Ba vein deposits from Spain and Chile, ...
Systematic tool to plan and evaluate demand side strategies during sustained energy crises in hydrothermal power systems
(Elsevier, 2015)
HARE, a systematic tool to evaluate demand side measures to face sustained energy supply risk in
hydrothermal power systems is presented in this paper. The main focus of the paper is to help centralized
planners to ...
Modeling marginal CO2 emissions in hydrothermal systems: Efficient carbon signals for renewables
(2017)
Reducing local and global emissions is one of the drivers behind the promotion of renewable energy technologies (RETs). Some RET projects (e.g. solar, marine power, and some biomass and wind) usually require supplemental ...
