Abstract: The present disclosure relates to a process for removal of an aerosol, comprising the steps of directing a process gas comprising an aerosol to contact an inertial demister providing a first demisted process gas, and directing the first demisted process gas to contact a coalescing demister providing a second demisted process gas, characterized in said first inertial demister being more open than said coalescing demister, where more open is defined as having a higher void fraction or a lower density with the associated benefit of such a process providing an efficient removal of a large volume of liquid from the inertial demister, while avoiding flooding of the demister system. It further relates to a process plant for sulfuric acid production employing such a pair of demisters.
