Suggest as many ways as you can think of to separate the 2 species. A and B with the presence of gas. Give examples of 2 species going to a separator with the presence of gas. What conditions would you need for each method to work?

The different processes for the separation of two different species has to be suggested.
Other than these processes, examples of species going to a separator with the presence of gas is also required to be mention along with proper conditions.
There are different species which required different methods for the separation in the chemical industries. This can be sum up as solid-solid separation, solid-liquid separation, liquid-liquid separation, Gas-solid separation, Gas-liquid separation, Gas-Gas separation.
In the question we are asked to separate the species which involves gas.
Thus, we are here considering the species which involves gas only along with other phase of the substances.
1. GAS-SOLID SEPARATION:-
(a) CYCLONE SEPARATOR
It is a separating method which which uses vortex separation without any filters to separate two substances. A cyclone is a device which consists of a vertical cylinder and a conical bottom along with a tangential inlet near the top. The dust cane from the inlet and moves along a spiral path. The centrifugal force due to this spiral motion is very strong then the gravitational force and thus it tends the particles always towards the wall and particles slide down into the cone and are collected. The more the density of the particle and less the temperature of the gas, more will be the efficiency of the cyclone to collect the particles.
Cyclones are used in oil industries for the fluid catalytic cracking to achieve fast separation, cement industries, etc.
(b) ELECTROSTATIC PRECIPITATOR
This device separates the dust particles and smoke from a flowing gas in a very fine form using a force of an induced electrostatic charge. This device is very efficient as it uses less energy for a particular separation. Particles with high resistivity are preferable as they cannot be charged easily and thus their charge cannot be lose on arrival at the collection electrode.
