SUMMARY OF MAJOR PROJECTS CFD analysis of Delta stacks Clarifier (Lake Charles, Louisiana): The objective of the project was to establish base CFD model that describes two-phase flow problem to find feasible options to improve the equipment performance at Lake Charles (US) Plant. The simulation was done for the simplified 3D geometry with discrete phase model (DPM) and the implementation of project is done in plant with MS project. The project was implemented by showing the tangible benefit of $ 180, 000/yr. Received W R GRACE Premier Award 2009 for innovation. CFD Analysis of Air-set Nozzle for Cavitation (Kautan, Malaysia): Atomization nozzle is the critical equipment in air-set silica gel manufacturing (Capriole). Sodium silicate mixes with sulphuric acid inside the nozzle and the mixed sol is sprayed to form particles. The whole atomizing process is completed within a second, and the basic properties of silica base gel are determined in this step. It is very important to understand the mixing and spraying phenomena for morphology, pilot demonstration, conceptual process design, and eventually scale-up to commercial unit. CFD model where developed to study the flow pattern and the pressure profile. The static pressure profile helps to learn the cavitation inside the nozzle. The mixture model was used with k-epsilon realizable model to learn the pressure profile. CFD Analysis of Jet Mixer (Lake Charles, Louisiana): Jet mixer is important equipment in Silica sol binder and FCC production. Modification of internal jet mixer may result in effective mixing of the acid alum with diluted sodium silicate to form silica sol binder as compared to that currently used in the Plant. During the mixing of the sodium silicate and acid solutions if mixing is not intensive enough and areas higher in pH occur, then small gel particles will form within the sol. The presence of gel will reduce the density and attrition resistance of the catalyst by reducing the amount of sol particles available for binding and by providing large particles of silica gel which are of low density and difficult to bind. Silica polymers are linear and/or branched polymers, but the gel is a three dimensional structure which incorporates essential all the silicate in solution. A CFD analysis for predicting the pressure profile and mixing efficiency model using the k-epsilon turbulence model and the Eulerian two phase model, the phase change is model using the Cavitation model in Fluent. CFD Study to Calculate Temperature profile in the Crystallizer (Valley Field, Canada) Objective of CFD model was to describe the temperature profile on crystallizer, the generally accepted crystallizer theory is that bigger is better because there is less heat loss and you can crystallize faster. How do we know what is the best size for a crystallizer? Since, we can't do the experiment in a 40,000 gal crystallizer. Thus CFD help us to identify what is the best size for a crystallizer, we took into account heat loss through the wall of the crystallizer and evaporative cooling through the top. The Continuity, Momentum, Energy and Specie Transport Equation were model in to Fluent to study the Crystallizer Temperature profile. Fluid Energy Mill Modeling (Curtis Bay, Maryland): The Fluid Energy Mills are present in all Grace Davison Product line around the world. Here the FEM of Curtis Bay Plant is studied for the optimization of operation. Several key design modifications distinguish the “new” improved 24” Curtis Bay C mill from the “old” model. The new mill incorporates a substantially higher, more evenly spaced total feed area, allowing a higher total amount of feed air to accompany solids into the mill. The feed is injected at modified angles, as is the grind air, and the grind air nozzles are slightly smaller in diameter. Governing equations are solved for Mass, Momentum, Compressible, Enthalpy, Turbulence/Dispassion Energy and Population Balance Equation for particle break-up. Comparison of airflow simulations for both the old and new C mills shows that improved flow dynamics are achieved in the new mill suggest more efficient energy usage and the potential for enhanced particle classification, smaller particle sizes and narrower particle size distributions of products. Modeling of Concrete Flow in a Rotating Drum Mixer (Cambridge, Massachusetts): Typical objectives were to evaluate the power required to operate a mixer (scale-up), for on-line process control, and to optimize mixing. The torque or power required to operate a mixer was modelled computationally using Fluent 12.0 based on the rheology, volume, and density of the fluid in the mixer and the geometry of the mixer. The results were produced to show shear rate, shear stress, and velocity distributions throughout drum (3-dimensional model and/or various longitudinal and lateral 2-dimensional sections) for all combinations of the concrete yield stress, plastic viscosity, density, and load size conditions. The User define function is written for defining the Plastic Viscosity of Bingham Fluid. (For Grace Construction Products) CFD analysis for Sirius Reactor Design (Edison, New Jersey): This Scale-up exercise was based on two criteria: Maximum local energy dissipation (in impeller region) and number of flow turnovers in the vessel. Impeller of choice was 4PBT45 impeller. The RPM and diameter were adjusted to achieve similar dissipation and flow. The existing 505 gal reactor has 32” diameter impeller running at 70 RPM performs satisfactory. The new 748 gal reactor was scaled-up to achieve similar results with 38” diameter impeller at 62.5 RPM. CFD analysis of thermal spray process (Curtis Bay, Maryland): An industrial HVOF thermal spray process was simulated using FLUENT. The macroscopic HVOF flow field consists of three major physio-chemical processes, transformation of chemical energy into thermal energy by the combustion of fuel, conversion of thermal energy into kinetic energy by the burning of gases by passing through the nozzle, and the transfer of momentum and heat from gases to the powder particles. All these processes are actually coupled together in the HVOF system. The grid was highly clustered near the exit of the torch. In prescribing the boundary conditions, the flow was considered radially symmetric at the centerline. In addition the mass flow rate was specified at the opening of each delivery tube. The gas pressure, velocity and temperature in the computational domain were initially patched using the udf DEFINE_INIT command. Due to high Reynolds number and large pressure gradients in the nozzle, the renormalized group (RNG) k-Epsilon turbulence model was used with non-equilibrium wall function to enhance prediction of wall shear and heat transfer. The particle in-flight behavior was studied. Finally the solution obtained was verified for grid independency.
