Liquid Liquid Mixing


Mixing is the operation involving the manipulation of a heterogeneous physical system to make it homogeneous. The whole process allows mass or heat transfer between one or two components, phases, or streams. A good example is a process of pumping water into a swimming pool to homogenize the temperature of the water in there. Using the right equipment makes mixing a liquid, gas, or solid into another liquid, gas, or solid.

Mixing Classification

The equipment and operation used in mixing will depend on the state of the mixed materials (solid, semi-solid, liquid) and the miscibility of the processed materials. The act of mixing in this context can be synonymous with kneading and stirring processes.
With the various classes of mixing, we are going to cover liquid-liquid mixing.

Liquid-Liquid Mixing

Liquid mixing frequently occurs in process engineering. The equipment used in liquid liquid mixing in 2021 is determined by the nature of the fluids to blend. There is single-phase and multi-phase blending. A single-phase blending involves low shear and mixers flowing at high rates, causing liquid engulfment. In multi-phase blending, it uses high shear and low flow mixers. It results in the creation of droplets of one liquid.

Types of Liquid-Liquid Mixing

It is divided into immiscible and miscible liquid-liquid mixing.

Blending is used to express the mixing of miscible liquids. Mixing is used for dispersions of immiscible liquids. It is used to mix hydrocarbons and water and alkaline or acidic solutions in the combination of organic fluids to produce various types of emulsion products.

Applications of Liquid-Liquid Mixing In 2021

Liquid-liquid mixing is used in unique process objectives. They include;

• Removal or addition of heat

• Solvent extraction


Liquid-liquid mixing in 2021 is vital in promoting good contact between two or more immiscible phases. It also extends the interfacial area, increasing the mass transfer rate.
