A new spray-drying system has been designed to overcome the limitations caused by existing designs. A key feature of the approach has been the systematic use of Computational Fluid Dynamics (CFD) to guide innovation in the design process. An example of an innovation is the development of a box-shaped transitional feature …
The removal efficiency of CO 2 as a function of operating temperature is shown in Fig. 2 with the inlet CO 2 concentration of 4%. As observed in the figure, with increasing the operating temperature, the reaction rate increases resulting in enhancement of the CO 2 removal efficiency. Fig. 2 shows that the maximum removal efficiency of …
2.1.2. Atomization. Atomization is a very important operation in spray drying process. It determines the distribution of droplet sizes in the resulting cloud and determines the energy required for atomization, the trajectory and velocity of particles leaving the atomizer forces the appropriate shape of the drying chamber. The droplet size …
Marsulex Environmental Technologies (MET) utilize a single or multi-atomizer configuration in their spray dryer design. The spray dryer is designed with flue gas dispersers to deliver even flow distribution around the atomizer wheel. This provides maximum interaction of the gas and the slurry for efficient SO 2 absorption and dry …
