The timing and selection of CO2 sources will affect the cost of achieving projected CCS based emission reductions. Performed process simulations and cost estimations clearly point out the impact of CO2 concentration and steam supply when capturing CO2 from an atmospheric gas stream with MEA-based...
ABSTRACT In this work the ash sintering behaviors and effects of aluminosilicates based additives (kaolin, zeolite 24A and zeolite Y) during combustion of wheat straw and barley husk were investigated. The sintering degrees of fuel ashes and corresponding mixtures with additives were evaluated...
A method for computer simulations of snow drift around man made structures is described. Particles are tracked in space and time based on a Lagrangian-Eulerian description of particle and wind velocities, respectively. Calculation of the wind phase is governed by the general Navier-Stokes equations...
Movements of 20 radio-tagged wild Atlantic salmon (Salmo salar) parr were studied 1.3 km downstream of a hydropower station. Ten parr were free-ranging and ten were restricted to an area near the river bank by a 75 m(2) rectangular containment pen that was flooded at high flow, but dry at low flow...
