Abstract:
The subject invention pertains to a continuous process for the production of aqueous paraffin emulsions. A primary emulsion is first formed by subjecting water and paraffin in admixture with an emulsifier and a portion of recycled primary emulsion to heat and turbulent flow. The stability of the primary emulsion is then improved by mixing said primary emulsion with another emulsifier and a portion of a recycled secondary emulsion and subjecting the mixture to heat and turbulent flow to produce said secondary emulsion. Finally, additional stability is achieved by homogenizing said secondary emulsion to produce a product emulsion.
