    dude...its Flaring, not flairing....
    1) While refining crude oil we get non condensable gases like C1 and C2 which are not economical if condensed using extensive pressurising and cooling processes in Refineries. So we divert these gases to Flare.
    2) In the process of refining we sometimes get our equipment over pressurised, this over pressure is released through safety valves to the Flare.
    3) We also get some toxic gases like H2S in the process of refining, we divert these to Flare.
    4) During shutdown and startup of the process plants, to stabilise the plant we also divert some non condensables, over pressure to the Flare.

    After the process of distillation of crude we get many undesirable product which are hazardous in nature , if we expose without combustion ,it creates pollution due to this we do combustion of all undesirable product inflar .

    first of all we should have the concept of the gases remove while treating in refinery operations they can be sox , carbon dioxide , carbon mono and other hazardous gases....... now back to key poin...

    1.To calculate free energy.
    2.chemical potential is 1 type of force to turn a reaction in equilibrium.
    3.chemical potential is comparable to escaping tendency or fugacity,its means the tendency of reaction flow to ewuilibrium point.
    4.If chemical potential is high escaping tendency will high.
