Clear-Water Scouring Process in a Flow in Supercritical Regime

Process Design for Supercritical Water Gasification

In this paper the layout of pilot plant (100 kg/h) for the supercritical water gasification (SCWG) of biomass is proposed. The proposed layout involves a reactor, units to separate water and hydrogen, a burner and several heat exchangers. This scheme was also simulated by means of the commercial software Aspen Plus (Aspen Tech, Inc.) in order to state the influence of different parameters such ...

investigation of flow regime in pore water flow through soil in crs consolidation test

the consolidation test method proposed by terzaghi and used in most soil mechanic laboratories has limitations and weaknesses. to get correct results, improvement and modification of the test method is essential. several experimental methods, such as constant loading rate, gradient and constant rate of strain (crs) have been used over the past 40 years. of these methods, crs is more advantageou...

Soil water regime and water concervation efficiency in a non-irrigated semi-arid environment

Supercritical Water Radiolysis Chemistry Supercritical Water Corrosion

The direct measurement of the chemistry in reactor cores is extremely difficult. The extreme conditions of high temperature, pressure, and radiation fields, are not compatible with normal chemical instrumentation. There are also problems of access to fuel channels in the reactor core. For these reasons, all reaction vendors and many operators have extensively used theoretical calculations and c...

Solvation in supercritical water *

Cochran, H.D., Cummings, P.T. and Karaborni, S., 1992. Solvation in supercritical water. Fluid Phase Equilibria, 71: 1-16. The aim of this work is to determine the solvation structure in supercritical water compared with that in ambient water and in simple supercritical solvents. Molecular dynamics studies have been undertaken of systems that model ionic sodium and chloride, atomic argon, and m...
