Abstract
A sulfuric acid production plant has a discontinuously operating back-up absorber to allow for sulfur emission control in situations where part of or even the entire sulfuric acid production plant is shut down, inoperable, or otherwise compromised. The back-up absorber receives lean solvent from a storage tank that is configured such that continuous operation of the back-up absorber is possible for several hours.
