Abstract:
A process for preparing a hydrocarbon in water emulsion, comprising the steps of:providing a liquid additive that tends to gel when mixed with water at temperatures less than a maximum gelling temperature TG of said liquid additive; providing a stream of water at temperature TC less than said maximum gelling temperature TG; feeding said stream to a static mixer having a mixer inlet so as to impart energy to said stream; adding said liquid additive to said static mixer downstream of said mixer inlet, whereby said liquid additive mixes with said stream and said energy is at an effective amount to inhibit inhibits gelling of said liquid additive at TC and so as to provide a substantially homogeneous solution of said liquid additive in said water; and mixing said solution with a hydrocarbon in a mixer so as to form a hydrocarbon-in-water emulsion.
