Add very heavy components from the top of the tower

Thread Content

Dear experts: The company currently extracts the finished product at the top of the T102 reactor, and light components always affect the quality of the product, accounting for about 3% of its composition. Now, the company intends to use azeotropic distillation to change the boiling point of these light components by adding heavy components to the reflux tank of the reactor T101, which is located before the finished product reactor; the amount of heavy components added is equal to the mass of the light components. Both Tower T101 and Tower T102 are negative-pressure towers, with a pressure drop of around 2 Kpa; the heavy components do not vaporize at either the top or the bottom of the towers. What I want to ask is, is it appropriate to add it from the return tank? Could the mist be carried back into the reflux tank, thereby causing the reflux tank to become enriched with heavier components? Also, what impact will adding it in this way have on the entire tower?
