Application of the method of discrete-pulse energy input for water degassing in municipal and industrial boilers [PDF]

Acta Periodica Technologica, 2022
The main advantages and disadvantages of chemical and physical degassing of liquids are considered. It was found that hydrodynamic cavitation should be considered as an important alternative to acoustic cavitation, both in terms of performance ...

Textural Insights Into the Evolving Lava Dome Cycles at Santiaguito Lava Dome, Guatemala

Frontiers in Earth Science, 2018
The structures and textures preserved in lava domes reflect underlying magmatic and eruptive processes, and may provide evidence of how eruptions initiate and evolve. This study explores the remarkable cycles in lava extrusion style produced between 1922

Chemical feedbacks during magma degassing control chlorine partitioning and metal extraction in volcanic arcs

Nature Communications, 2021
Chlorine behaviour during complex, polybaric arc magma degassing is poorly understood. Here, the authors show that chemical feedbacks during coeval magma differentiation and degassing account for the Cl record at both volcanoes and ore deposits, and ...
