Title
(EN) GAS TURBINE TOPPING IN SULFURIC ACID MANUFACTURE
(FR) PRODUIT DE TÊTE DE TURBINE À GAZ DANS LA FABRICATION D'ACIDE SULFURIQUE
Abstract
(EN)
A sulfur-burning combustor generates hot sulfur dioxide that is mixed with dry air or recycled sulfur dioxide to form a mixed working gas for a gas turbine to ensure that the temperature of the working gases is kept below the maximum allowable temperature of the blades of the turbine. The turbine drives an oxygen compressor which supplies oxygen to a bubbling chamber which also receives S8 to produce sulfur vapor (predominantly diatomic sulfur) for combustion. By using stoichiometric quantities, the end product, sulfur dioxide, is delivered in requisite quantities to a sulfuric acid plant without any harmful emissions. Useful amounts of electrical power can thus be generated by the gas turbine (topping device) as well as the downstream steam turbine by harnessing the enormous amount of waste heat involved in the manufacture of sulfuric acid.

La présente invention concerne une chambre de combustion consommant du soufre générant du dioxyde de soufre chaud qui est mélangé avec de l'air sec ou du dioxyde de soufre recyclé pour former un gaz de travail mixte pour une turbine à gaz afin d'assurer que la température des gaz de travail soit maintenue en-dessous de la température maximale permissible des aubes de la turbine. La turbine entraîne un compresseur d'oxygène qui fournit de l'oxygène à une enceinte de formation de bulles qui reçoit également du S8 pour produire de la vapeur de soufre (majoritairement du soufre diatomique) pour la combustion. Grâce à l'utilisation de quantités stoechiométriques, le produit final, du dioxyde de soufre, est obtenu en des quantités requises par une installation d'acide sulfurique sans émissions nuisibles. Des quantités utiles d'énergie électrique peuvent ainsi être générées par la turbine à gaz (dispositif de produit de tête) ainsi que la turbine de flux aval grâce à l'utilisation de l'énorme quantité de chaleur résiduelle dégagée par la fabrication de l'acide sulfurique.
