High-intensity mixing

Most dispersed gas units contain three or four cells. Bulk water moves in series from one cell to the other by underflow baffles Field tests have indicated that the high intensity mixing in each cell creates the effect of plug flow of the bulk water from one cell to the next. That is, there is virtually no short-circuiting or breakthrough of a part of the inlet flow to the oudet wier box.

For when a large amount of absorption is needed with no need for high purity effluents venturi scrubber with high intensity mixing (usually 1 theoretical stage). Related to Section 5.2. 

As the viscosity of the liquid increases, droplet sizes tend to get larger. Increased torbrrlence resulting from high-intensity mixing permits this reaction to be achieved rapidly. Energy is imparted to the combustion air of the combustor and this in tom permits more rapid mixing (tor-bulence) of the air with the fuel droplet. 

In 1994, Monsanto patented a process to recycle aU the components of postconsumer nylon 6,6 carpet, without separation, into a filled thermoplastic product suitable for injection molding [62, 63]. It used a twin-screw extruder to accomplish high-intensity mixing of the thermoplastic from carpet samples. The recycled material contained 35-67 wt% nylon, 8-21 wt% polypropylene, 5-29 wt % SBR, and 10-40 wt % inorganic filler. In one study, no compatibilizer was used [62]. The carpet samples were fed directly into a twin-screw extruder operating at about 250-260°C and at a shear rate of 200-400 s The tensile... 

Continuous Saponification. There are several types of continuous systems, each with their own benefits and drawbacks. The basic premise is that continuous mixing is not required after the poly(vinyl acetate) and the caustic is mixed (220). Several designs for the high intensity mixing imit have been suggested in order to obtain efficient mixing and little fouling (221,222). 

Efficiently blending the chemical into the process water is often an overlooked but crucial process that can affect the effectiveness and cost of chemical treatment. Many chemical applications need almost instantaneous dispersion for maximum effectiveness. Depending on the chemical properties (that is, viscosity, miscibility, concentration), this can require high-intensity mixing or gentle blending with the process water. 

Banbury mixer (Figure 16-17). Again, the short L/D shafts are supported at each end, and very high intensity mixing is possible (Canedo and Valsamis, 1998). Discharge is radial, with a variable restriction to control the holdup. A separate melt extruder is used to develop pressure for pelletizing.
