Abstract
Esta invencion se refiere a un proceso y un equipamiento para la preparacion de Acido sulfUrico en la cual el gas de partida que contiene dioxido de azufre es transformado por oxígeno en por lo menos dos etapas de contacto de contactos principales es transformado en parte a trioxido de azufre y que el gas producido que contiene trioxido de azufre es conducido a un absorbedor y ahí transformado a Acido sulfUrico. Para poder transformar gases de partida con 13 a 66% en volumen de dioxido de azufre a Acido sulfUrico en forma economica con el empleo de catalizadores convencionales, se recomienda sacar un flujo parcial de gases de dioxido de azufre y trioxido de azufre de una etapa de contacto que precede a la Ultima etapa de contacto principal y agregar este flujo parcial al gas de partida para generar un gas de contacto con un contenido de dioxido de azufre de mAs de un 13% en volumen y llevar Éste a la primera etapa de contacto.This invention relates to a process and equipment for the preparation of sulfuric acid in which the starting gas containing sulfur dioxide is transformed by oxygen in at least two stages of contact of main contacts is partly transformed to trioxide of sulfur and that the gas produced containing sulfur trioxide is taken to an absorber and then transformed into sulfuric acid. To be able to transform starting gases with 13 to 66% by volume of sulfur dioxide to sulfuric acid in an economical way with the use of conventional catalysts, it is recommended to take a partial flow of sulfur dioxide and sulfur trioxide gases from a stage of contact that precedes the last stage of main contact and add this partial flow to the starting gas to generate a contact gas with a sulfur dioxide content of more than 13% by volume and bring this to the first contact stage.
