Title
(EN) BACK-UP CONFIGURATIONS AND METHODS FOR SULFURIC ACID PLANTS
(FR) CONFIGURATIONS ET PROCÉDÉS DE SECOURS POUR INSTALLATIONS DE PRODUCTION D'ACIDE SULFURIQUE
Abstract
(EN)
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.
(FR)
Selon l'invention, une installation de production d'acide sulfurique possède un absorbeur de secours qui fonctionne de manière discontinue afin de permettre une régulation des émissions de soufre dans des situations où une partie ou même la totalité de l'installation de production d'acide sulfurique est à l'arrêt, dans un état de non fonctionnement ou autrement compromise. L'absorbeur de secours reçoit du solvant pauvre provenant d'un réservoir de stockage qui est configuré de telle sorte qu'un fonctionnement continu de l'absorbeur de secours est possible pendant plusieurs heures.
