- Abstract
Reactor fouling caused by preformed latexes is investigated using 50 wt% solids content latexes of different colloidal stability. In the absence of agitation, a rapid adsorption equilibrium is achieved for pH below the isoelectric point of the stainless steel (pH = 4.3). The equilibrium fouling decreases as solids content decreases and by increasing the pH above the isoelectric point of the stainless steel. The stability of the latex is a major factor determining fouling, which strongly decreases as latex stability increases. Under agitation, fouling increases with time, solids content, and temperature, and it decreases as the colloidal stability of the latex increases. The flow patterns in the reactor determine the distribution of fouling in the baffles. A mechanism for fouling formation is proposed by combining computational fluid dynamics and experimental results.
