Abstract
Sulphuric acid plants, separators for separating entrainment for process gas, and gas treatment processes for generating sulphuric acid are provided. The sulphuric acid plant comprises a source of process gas, an entrainment eliminator, a gas rotator located downstream of the gas-liquid contactor, and a separator located downstream of the entrainment eliminator and upstream of the gas rotator. The separator comprises a plurality of passages. Each passage comprises a vane extending longitudinally along the passage, wherein each vane rotates a process gas flowing through the separator. The process comprises transferring process gas from an entrainment eliminator to a separator located downstream of the entrainment eliminator, rotating the process gas through the separator to separate entrainment, and transferring the separated process gas from the separator to rotating equipment located downstream of the separator.
