摘要： Embodiments of the present disclosure are directed to systems and methods of removing carbon dioxide from a gaseous stream using magnesium hydroxide and then regenerating the magnesium hydroxide. In some embodiments, the systems and methods can further comprise using the waste heat from one or more gas streams to provide some or all of the heat needed to drive the reactions. In some embodiments, magnesium chloride is primarily in the form of magnesium chloride dihydrate and is fed to a decomposition reactor to generate magnesium hydroxychloride, which is in turn fed to a second decomposition reactor to generate magnesium hydroxide.

摘要： The present invention relates to a process for the separation of strong acid from its salts. In said process, a strong acid salt is reacted with organic weak base (OWB) in the presence of a hydrophilic solvent and CO2. The cation of the strong acid salt is precipitated to produce a carbonate/bicarbonate salt and the strong acid form a liquid salt with the OWB. The above process is performed in a solution comprising both the strong acid salt and the WBO. In the next step, the strong acid is released from its OWB liquid salt and the OWB is returned to a previous step.

摘要： Disclosed herein are embodiments of a method and system for producing a halogen gas. The method may comprise contacting a solid oxidizing agent with a vapor comprising a halide compound, to produce a gas stream comprising a halogen corresponding to the halide in the halide compound. The halide compound may be an acyl halide, such as an acetyl halide or an oxalyl halide. The oxidizing agent may be any suitable oxidizing agent, and in certain examples, potassium permanganate is used. The method may be performed under a reduced pressure. Also disclosed herein is a system suitable to perform the disclosed method. The system may comprise a reservoir, an oxidizing agent support and a gas stream outlet.

摘要： The invention pertains to a method for providing a succinic acid solution, comprising the steps of —providing a first magnesium succinate containing medium with a magnesium succinate concentration of 18-23 wt. % to a first acidification reactor where it is contacted with hydrogen chloride to form a solution of succinic acid, magnesium chloride and hydrogen chloride, —providing a second magnesium succinate containing medium with a magnesium succinate concentration of 25-50 wt. %, and contacting it in a second acidification reactor with the solution of succinic acid, magnesium chloride and hydrogen chloride withdrawn from the first acidification reactor, to form an aqueous mixture comprising magnesium chloride and succinic acid with a succinic acid concentration of at least 18 wt. %. The method according to the invention makes it possible to obtain a solution comprising succinic acid and magnesium 20 chloride with an increased succinic acid concentration.

摘要： The invention pertains to a method for preparing succinic acid which comprises providing an aqueous magnesium succinate solution to an acidification step, wherein the magnesium succinate solution is acidified by the addition of hydrogen chloride, thereby obtaining an aqueous solution comprising succinic acid and magnesium chloride and subjecting the aqueous solution comprising succinic acid and magnesium chloride derived from the acidification step to a treatment step with active carbon followed by precipitating succinic acid from an aqueous mixture comprising succinic acid and magnesium chloride resulting from the active carbon treatment step in a precipitation step to form solid succinic acid. It has been found that the method according to the invention leads to succinic acid crystals with better properties than a comparable method wherein no active carbon treatment is used.
