Abstract :
In Iran, paper industry was first started with the establishment of a mill factory and using waste paper in 1313 solarium in Karaj. For 15 years, with the establishment of two Pars paper making factories in the Haft Tapeh of Khuzestan and the Iranian wood and paper plant (Chouka) In Gilan, it has become a modern and advanced technology. Paper and paperboarding is industrial capital, and the time it takes to apply new processes is generally very high. Under these circumstances, the replacement of expensive equipment only takes place when major rebuilding and launch of new production lines. So far, only a small number of nanotechnology applications have been used in the paper industry, one of the most famous of which is the use of nano / microparticles (colloidal silica, aluminum chloride hydroxide) combined with cationic polyetherolones. In this paper, it is determined that increased pressure increases the absorption of SO2. The more pressure it produces, the greater the absorption.
