Abstract: In a process for safe production of phosgene (COCI2) from carbon monoxide and chlorine according to the reaction scheme CO (g)+Cl2 (g)−>COCI2 (g) in a plant with a capacity of phosgene below 10 t/hr, the CO is produced on site from a feed stock based mainly on CO2. The plant preferably comprises a solid oxide electrolysis cell (SOEC) stack system producing CO for use together with chlorine in the phosgene synthesis. This way of producing phosgene is based on using primary raw materials for which escape concentrations above 1000 ppm or even above 10000 ppm or 10% will not result in any health risk.

Abstract: A method for the purification of a raw gas stream by selective catalytic oxidation, in which organic and inorganic sulfur compounds, halogenated and non-halogenated volatile organic compounds are selectively oxidized without substantially oxidizing the lower hydrocarbons and the sulfur containing compounds present in the gas to sulfur trioxide and excess of oxygen is removed by oxidation of lower alcohols, ethers or hydrogen added to the raw gas stream upstream the catalytic oxidation.

Abstract: In a process for the removal of siloxanes from biogas streams, especially a landfill gas stream or a gas stream from anaerobic digesters, the gas stream is first passed through a conventional siloxane removing unit to remove the majority of the siloxanes and subsequently passed over a selected catalyst with polishing effect, thereby removing remaining traces of siloxanes. The catalyst with polishing effect is chosen from i.a. zeolites, porous silica, titania and various metals on alumina or titania.

Abstract: A method for removing hydrogen sulfide (H2S) from an acid gas comprises feeding the gas to a membrane separation unit, collecting the product gas from the membrane unit, heating the permeate stream to the necessary inlet temperature for catalytic oxidation of H2S and feeding the heated permeate stream to a catalytic oxidation unit, where H2S is oxidized to SO2. The heating of the permeate stream is accomplished by using a fraction of the feed gas to heat the permeate stream in a separate heater or by using a steam-fired heater. The method is especially suited for use on an off-shore facility.

Abstract: The invention concerns a process for monitoring failure situations related to feed and/or purge flow in electrolyser cells, stacks or systems, said monitoring process being combined with appropriate actions to be taken in case of such failure situations, wherein (a) the current and/or the voltage are monitored and controlled over a single cell, over all the cells or over one or more selected cells in a stack or a system of stacks, (b) in case the current, the voltage or the ratio between voltage and current crosses its pre-defined threshold value, a failure mode is detected and communicated to the control system, and c) the voltage levels of the system are adjusted to be within safe limits (safe-mode limits).
