A circuit for flicker suppression in a Light Emitting Diode has a latch. More particularly, an exemplary embodiment of the present invention relates to a process which mixes PLS with an acid source, preferably lean electrolyte, to induce formation of colloidal silica that can then be collected and removed. In one aspect, embodiments disclosed herein relate to a process for dispersing foulants in a hydrocarbon stream, including the steps of: determining a nature of foulants in a hydrocarbon stream; selecting a solvent or a mixture of solvents suitable to disperse the foulants based upon the determined nature; and contacting the foulants with the selected solvent or mixture of solvents.
