Process for removing SO/sub 2/ from gases
Patent
·
OSTI ID:5802677
The invention relates to a method for the treatment of industrial effluent gases for the removal of sulfur dioxide in which the gases are contacted with an absorbing solution, before the contact stage is pre-treated with air or other gas inert to the solution, preferably a gas devoid of oxygen, whereby the SO/sub 2/ partial pressure of the solution is reduced, thus enhancing the SO/sub 2/ removal from said effluent gases.
