Abstract: The present invention provides a process for removing ammonia as an aqueous salt solution from an acid gas comprising ammonia and hydrogen sulfide. A strong acid, such as sulfuric acid, is used as a scrubbing agent to convert ammonia to an ammonium salt. Control of pH and stripping in combination with reboiler or evaporators reduces hydrogen sulfide concentration. The ammonium salt is produced as an aqueous solution, which may crystallized to form a solid product. The ammonium salt solution or solid may be used as a fertilizer.

Abstract: The invention relates to a process for the treatment and purification of dangerous wastes containing ammonium salts, particularly ammonium chloride, derived from pharmaceutical and chemical technologies. The process includes the following steps: removing the organic solvent content of the waste mixture, containing an aqueous and non-aqueous phase, by phase separation based on the difference in the special weight and/or by azeotrop distillation, and heating the obtained aqueous solution at its boiling point or at a temperature belonging to the maximal saturation boiling point of the ammonium salt until the non-solvent type organic substances precipitate in the form of a well separable polymerisate phase, whereafter this phase is separated from the aqueous solution of the ammonium salt and the ammonium salt, preferably the ammonium chloride is purified by a method known per se.

Abstract: Disclosed are processes and systems for sequestering carbon dioxide from a flue gas effluent from a parent process such as a coal-fired electric power plant. In one non-limiting embodiment of the invention, a mineral having a metal is dissolved with an acid to provide a solution having a predetermined pH. Carbon dioxide from the flue gas effluent and a base are added to the solution to provide a metal carbonate reaction to precipitate a metal carbonate, e.g., magnesium carbonate, from the solution. Heat, which may be supplied by the flue gas effluent, is used to power a base management system for recovering used base from the process. A process for producing metal salt from a mineral (such as olivine or serpentine) is also disclosed.

Abstract: A method for recovering inorganic salt during processing of a lignocellulosic feedstock is provided. The method comprises pretreating the lignocellulosic feedstock by adding an acid to the feedstock to produce a pretreated lignocellulosic feedstock. A soluble base is then added to the pretreated lignocellulosic feedstock to adjust the pH and produce a neutralized feedstock. The neutralized feedstock is then enzymatically hydrolyzed to produce an enzyme hydrolyzed feedstock and a sugar stream. Inorganic salt is recovered from either a stream obtained from the lignocellulosic feedstock prior to the step of pretreating, a stream obtained from the pretreated lignocellulosic feedstock, a stream obtained from the neutralized feedstock, a stream obtained from the sugar stream, or a combination of these streams. The inorganic salt may be concentrated, clarified, recovered and purified by crystallization, electrodialysis drying, or agglomeration and granulation, and then used as desired, for example as a fertilizer.
