Abstract
A process for treating a plurality of by-product streams containing chlorosilicon compounds. The process comprises the steps of determining the average SiCl functionality of a plurality of by-product streams comprising chlorosilicon compounds, blending at least two of the by-product streams to form a blended by-product stream having an average SiCl functionality greater than or equal to 2.8, adding to the blended by-product stream a surfactant having a HLB number within range of about 3 to 28, and contacting the blended by-product stream with an aqueous medium at a temperature within a range of about 50.degree. C. to 120.degree. C. to form a granular siloxane gel.
