A high-shear mixer disperses, or transports, one phase or ingredient (liquid, solid, gas) into a main continuous phase (liquid), with which it would normally be immiscible. A rotor or impeller, together with a stationary component known as a stator, or an array of rotors and stators, is used either in a tank containing the solution to be mixed, or in a pipe through which the solution passes, to create shear. A high-shear mixer can be used to create emulsions, suspensions, lyosols (gas dispersed in liquid), and granular products. It is used in the adhesives, chemical, cosmetic, food, pharmaceutical, and plastics industries for emulsification, homogenization, particle size reduction, and dispersion.

Process for pretreating cracked gas before caustic tower treatment in ehtylene plants
InactiveUS6235961B1Improve efficiencyIncrease capacityThermal non-catalytic crackingCatalytic crackingProduct gasTower
An inline, high-shear mixer is provided in a cracked gas stream upstream of a caustic tower in an ethylene production unit. Spent caustic is withdrawn from the bottom of the caustic tower and pumped to the mixer, where the spent caustic mixes with and absorbs acid gas components from the cracked gas stream. The spent caustic is separated from the cracked gas, forming a partially treated cracked gas stream. The partially treated cracked gas stream is then fed to the caustic tower. Polymer deposition in the caustic tower is reduced because polymeric material is formed when the cracked gas stream is mixed with the spent caustic and is removed before the cracked gas stream is fed to the caustic tower.

A high shear mixer in a holding tank is used in a continuous flow process. Flow rate of material into and out of the holding tank establishes residence time in contact with shearing elements. A batch shear mixer is used in a tank that has continuous flow into the bottom and out of the top. A level controller controls a valve or a positive displacement pump at the inlet. The mixing chamber is sized for the maximum needed residence time, slowing the flow increases the residence time. In an open tank lower inlet pump and upper outlet pump are coordinated.
