Abstract
The present invention relates to the production of dispersions and is particularly suitable for making dispersions with a viscous or solid dispersed phase in a continuous phase with a lower viscosity.
Claims61
A process for making a dispersion using a device comprising at least one separating means that separates two streams, involving the steps of:
- allowing a flow of stream 1 into stream 2 through a device comprising at least one separating means, such that stream 1 is dispersed in stream 2,
- optionally, continuing said flow of stream 1 into stream 2 such that the continuous and the dispersed phase can be inverted, and
- inversion of the said two phases,
- resulting in a dispersion of the material of stream 2 in the material of stream 1.
1 more element
The process of any of the previous claims wherein the separating means is formed by at least one membrane.
