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 gelling temperature T ; providing a stream of water at a temperature T less than the gelling temperature T ; feeding said stream to a mixer having a mixer inlet so as to impart energy to the stream; adding the liquid additive to the stream downstream of the mixer inlet, whereby the liquid additive mixes with the stream and the energy inhibits gelling of the liquid additive so as to provide a substantially homogeneous solution of the liquid additive in the water; and mixing the solution with a hydrocarbon in a mixer so as to form a hydrocarbon-in-water emulsion. In further accordance with the invention, different emulsions can be formed and combined so as to provide a combined emulsion having desired properties.

Preparation of stable emulsion using dynamic or static mixers

The present invention relates to a method for designing handling systems such as pipeline systems for fluid products such as emulsions and dispersions which deteriorate at elevated temperature and pressure. The method of the present invention comprises the steps of providing a pipeline having a fluid inlet point and a fluid discharge point and at least one pump for transporting the fluid from the fluid inlet point to the fluid discharge point, selecting one of a maximum pressure drop to be encountered by the fluid as it travels from the fluid inlet point to the fluid discharge point and a maximum volume of fluid to be handled by the system, and operating the system in accordance with the following equation: ##EQU1## where B is the maximum allowable shear rate from a first fluid inlet point to a second fluid discharge point, D is the diameter of the pipeline, and Q is the volume of fluid to be transported between the fluid inlet point and the fluid discharge point.
