A Transient, One-Dimensional, Discrete-Element Transport Model For Predicting Hydrodynamic Conditions And Three-Layer Non-Equilibrium Pollutant Concentrations As Dissolved In Water And As Adsorbed On Different Classes Of Sediment In Controlled Rivers And Tidal Estuaries, Gary W. Zimmerman

Masters Theses

A transient one-dimensional mathematical model for simulating the transport of pollutant effluents from industrial plants is presented.

The Eulerion fluid-in-discrete-element (FLIDE) formulation employs the integral forms of the conservation principles of water mass, sediment mass, and pollutant mass in variable size discrete elements that span the flow region. The transport of the pollutant effluents are modeled as dissolved and adsorbed suspended sediment in the suspended sediment and slurry sediment layer and as dissolved and stationary resident sediment in the resident sediment layer.

The contributions of vertical variations of the velocity components and pollutant concentrations in the suspended sediment and slurry …

Removal Of Sulfur Dioxide And Nitric Oxide From A Flue Gas Stream By Two Sodium Alkalis Of Various Sizes, John R. Carson

Masters Theses

The primary purpose of this research effort was to examine the dry removal of SO₂ and NO from a flue gas stream by injecting two sodium additives into a pilot bag house system. The additives tested were NaHCO₃ and Na₂CO₃ dusts with mass mean diameters ranging from approximately 30 to 200 microns. The Na₂CO₃ was obtained by decomposing the NaHCO₃ (with heat) prior to testing. The bag house temperature was maintained at either 250 or 300 degrees F.

It was demonstrated that 70% SO₂ removal can be attained with NaHCO …
