Abstract: The present disclosure relates to a process for removal of an aerosol, comprising the steps of directing a process gas comprising an aerosol to contact an inertial demister providing a first demisted process gas, and directing the first demisted process gas to contact a coalescing demister providing a second demisted process gas, characterized in said first inertial demister being more open than said coalescing demister, where more open is defined as having a higher void fraction or a lower density with the associated benefit of such a process providing an efficient removal of a large volume of liquid from the inertial demister, while avoiding flooding of the demister system. It further relates to a process plant for sulfuric acid production employing such a pair of demisters.

Abstract: In a process for steam reforming of oxygenates, especially at low steam-to-carbon (S/C) ratios, a feed gas containing oxygenates, such as ethanol, is converted into syngas over a ternary carbide catalyst. Then the reformed gas is either transformed into desired chemicals or mixed into the feed stream to the reformer in a plant, such as an ammonia or methanol plant. The preferred ternary carbide is nickel zinc carbide.

Abstract: The present invention relates to a method and a system for catalytic oxidation of a lean H2S stream. More specifically, the invention concerns a novel way of removing sulfur dioxide (SO2) formed by catalytic oxidation of hydrogen sulfide (H2S) with the purpose of removing H2S from a gas. This catalytic oxidation of H2S yields sulfur dioxide (SO2) through the use of known catalysts, so-called SMC catalysts.

Abstract: Oxygen is removed from a gas feed such as a landfill gas, a digester gas or an industrial CO2 off-gas by heating the feed gas, optionally removing siloxanes and silanols from the heated feed gas, optionally removing part of the sulfur-containing compounds in the heated feed gas, injecting one or more reactants for oxygen conversion into the heated feed gas, carrying out a selective catalytic conversion of any or all of the volatile organic compounds (VOCs) present in the gas, including sulfur-containing compounds, chlorine-containing compounds and any of the reactants injected, in at least one suitable reactor, and cleaning the resulting oxygen-depleted gas. The reactants to be injected comprise one or more of H2, CO, ammonia, urea, methanol, ethanol and dimethyl ether (DME).

Abstract: In a process for the oxidation of a lower alkene, such as ethylene, over a catalyst containing Cu and one or more zeolite or zeotype materials, the oxidation is conducted in the presence of ammonia in the feed gas at a process temperature below 350° C. The oxidation can be performed in a continuous process.

Abstract: A process for the cleaning of a lean gas stream contaminated with volatile organic compounds and/or sulfur-containing compounds comprises the steps of adding ozone to the contaminated lean gas stream and contacting the resulting ozone-containing gas stream with a catalytic device at a temperature down to room temperature. Depending on the content of particulates in the lean gas stream, the catalytic device is either a monolithic catalyst or a catalytic bag filter, both impregnated with a catalyst containing one or more metal oxides, in which the metal is selected from vanadium, tungsten, palladium and platinum.
