In this section the model for a continuous evaporative crystallizer is discussed. The crystallizer is of the draft tube baffled (DTB) type and is equiped with a fines removal system consisting of a large annular zone on the outside of the crystallizer (see Figure 1). In order to vary the dissolved fines flow without changing the cut-size of the fines removal system, the flow in the annular zone is kept constant and the flow in the dissolving system is varied by changing the recycle flow rate. The model assumptions are ...

Preparing a Brine Sludge Dissolving System for Maintenance... 

The dissolving system was scheduled for maintenance while the rest of the unit continued at full production rates. The chemical process operator was concerned about the available room in the sump as the slurry accumulated during the two- to three-hour outage. The operator drastically increased the slurry flow-rate into the dissolving system for about an hour and a half period before the shutdown. However, he only increased the flow of acid into the system slightly during that time. The basic process is shown in Figure 4—3.

In contrast to aqueous-dissolved systems where the OH radical and the H atom are the main initiators, radical cations plus electrons and excited states are formed in the solid state. This is also the case with cellulose dispersed in water [101]. The radical cations are transformed by deprotonation [e.g. reactions (57) and (58)]. These suffer fragmentation such as reactions (20) - (23), as discussed above, or, for example, reaction (59).

It was necessary to appropriately define the diffusion coefficients that appear in all of the preceding transport equations. It was demonstrated [61] that in dissolving systems there exists a critical solvent concentration, u, at which the mode of mobility of the polymer chains undergoes a change. This was mathematically expressed as a change in the diffusivity and was represented as...
