The invention relates to a continuous process for purifying a gas containing 60-99 percent SO(sulfur dioxide) by volume and 1 to 40 percent steam by volume, followed by synthesis of SO(sulfur trioxide) without first drying the gas, and to an apparatus for carrying out said method.

Continuous process and apparatus for purifying SO2-containing gases

Process for the continuous catalytic complete or partial oxidation of a starting gas containing from 0.1 to 66% by volume of sulphur dioxide plus oxygen, in which the catalyst is kept active by means of pseudoisothermal process conditions with introduction or removal of energy; apparatus for the continuous catalytic complete or partial oxidation of a starting gas containing sulphur dioxide and oxygen having at least one tube contact apparatus in the form of an upright heat exchanger composed of at least one double-walled tube whose catalyst-filled inner tube forms a reaction tube, with heat being transferred in cocurrent around the reaction tube and an absorber for separating off SOdownstream of the tube contact apparatus; the reactivity of the catalyst being preset by mixing with inert material.

[object Object]

A process for adjusting a circulating fluidized bed, wherein a part of the carrier gas is recovered, mixed with a propellant and returned to the fluidized bed as a carrier gas.
