Abstract: Flue gases etc. may contain SO2 which should be prevented from admission to the atmosphere. SO2 is oxidized to SO3 and condensed with steam to H2SO4-vapours which are condensed in vertical glass tubes cooled from the outside. In principle the condensate is collected near the bottom of the tubes. In the cooling process a mist of very small H2SO4 droplets is formed and tends to escape to the atmosphere. Environmental regulations continually increase the demands on reducing the amount of acid mist escaping. According to the invention an important method to achieve a reduction of the escape of acid mist is to pass the gas leaving each tube through an aerosol filter in gastight connection with the tube top. Such a filter may consist of acid resistant fibres or filaments having a thickness of 0.04-0.7 mm and may be arranged in specified manners to ensure a drop of pressure through below 20 mbar. Moreover, the sulfuric acid caught in the filter is caused to flow downwardly through the tube countercurrently with the feed gas. Various embodiments of filters and filter media for the purpose are disclosed. The sulfuric acid recovered is highly pure and highly concentrated.

Abstract: A process for the conversion of sulphur dioxide contained in a feed gas to sulphur trioxide, comprising the steps of a) alternatingly providing a first feed gas containing a high concentration of sulphur dioxide and a second feed gas containing a low concentration of sulphur dioxide as a process gas, b) preheating the process gas by heat exchange with a heat exchange medium, c) reacting the process gas in the presence of a catalytically active material in a catalytic reaction zone, d) converting at least in part the sulphur dioxide of the process gas into sulphur trioxide contained in a product gas in the catalytic reaction zone, e) cooling the product gas by contact with a heat exchange medium, wherein a thermal buffer zone is provided in relation to one of said process steps, providing thermal energy produced during super-autothermal operation for heating the process gas during sub-autothermal operation.

Abstract: In sulphuric acid production by oxidation of SO 2 into SO 3 and subsequent hydration of SO 3 , from feed gases having a varying SO 2 concentration, the stability and thermal efficiency of the sulphuric acid plant can be increased by configuring the catalytic reaction zone to match the requirements for conversion. This can be done by appropriate flow and reactor configuration, such as by-passing one or more sections of catalytically active materials, or leading the feed gas through a limited catalytic reaction zone in the case of low SO 2 concentration. The associated benefits are catalytic reaction zones having fewer, smaller and more predictable temperature gradients compared to a plant in which the varying feed gas is directed through the same reaction zones. The invention also relates to a reactor for carrying out the process, and a sulphuric acid production process comprising the conversion process.

Abstract: When condensing sulfuric acid from gases containing sulfuric acid vapour and steam in excess, e.g. originating from a power station, a substantial decrease of the amount minute droplets of sulfuric acid (the so-called acid mist) escaping to the surroundings is obtained, even in cases where the sulfuric acid plant is equipped with an aerosol filter, if minute nucleation cores are incorporated into the gas in an amount of 10 to 10 solid particles per Nm per 0.1 % H2SO4-vapour in the gas. The nucleation cores may, e.g., be generated by combusting hydrocarbons with >2 carbon atoms or silicones, or added as smoke from an electric arc or welding.

Abstract: A Process for removal of up to 99,9 % of H 2 S and other S-compounds and up to 99% of siloxanes in biogas and other gases comprising CO 2 and CH 4 , based on selective absorption in an absorption tower of SO 2 or H 2 S in concentrated sulfuric acid comprising peroxy disulfuric acid (H 2 S 2 O 8 ) and peroxy sulfuric acid (H 2 SO 5 } oxidizing H 2 S and SO 2 to H 2 SO 4 comprising the consecutive steps of : (1) compressing the gas to 3 pressure above 3 bar, typically 5-40 bar, and condensing its content of H 2 O typically at 30 - 40 °C (2) heating the gas to typically 200-250 °C and oxidizing its content of S-compounds selectively to SO 2 by a catalyst comprising oxides of V and Ti with a small excess of O 2 added to the gas in step (1), (3) cooling and condensing H 2O at 0 -50 °C, typically at 20 - 40 °C (4) oxidizing the SO 2 and H 2 S in the biogas to H 2 SO 4 by contacting the gas at about 100 °C in an absorption tower with recirculating hot concentrated sulfuric acid comprising H 2 S 2 O 8 generated preferably by electrolysis of H 2 SO 4 in an electrolyzer inserted in said recirculation of concentrated sulfuric acid. The formation of the H 2 S 2 O 8 in the electrolyzer also ensures maintenance of high concentration of the circulating acid as H 2 O is consumed in the over-all process. Siloxanes in the gas are absorbed and dissolved in the concentrated sulfuric acid while CH 4 , CO 2 and O 2 in the gas pass unaffected through the sorption tower. In a potential!y much more advantageous but not so well validated simplified version of the Process, seen in fig 1 and 3, the gas is passed directly from step (1) to step (4) for direct oxidation of H 2 S to H 2 SO 4 in the sorption tower. The effluent gas from the sorption tower can be passed to applications such as combustion in gas turbines or engines, or to further steps of ultra purification upstream of catalytic reduction with H2 of the C02 in the gas to CH 4 , methanol or higher hydrocarbons. The Process consumes only biogas and electricity and produces no byproducts apart from condensed water, a stream of useful concentrated sulfuric acid equivalent to the amount of sulfur in the biogas and a stream of useful H 2 from the electrolysis of H 2 SO 4 . The digester should be operated with highest possible content of H 2 S, 1-2 % or more, in the gas passed to the process of the invention.
