A method of removing inert gas dissolved in liquid ammonia involves evaporating, compressing, and then condensing the liquid ammonia together with the inert gas dissolved therein. Thereby, a product stream of warm liquid ammonia that has been freed of the inert gas is obtained, which is under elevated pressure relative to standard pressure and hence suitable for immediate use in methods in which pure liquid pressurized ammonia is required. If, by contrast, the ammonia is cooled first, for example, below the boiling temperature for ammonia and expanded to standard pressure to store it in tanks as liquid ammonia at low temperatures, it is necessary first to reheat and compress it for further processing operations. Thus the disclosed methods lead to significant energy savings.

A method for processing a liquid medium, wherein the medium to be processed is conducted through a liquid circuit and the medium to be processed is heated up in the liquid circuit with the aid of a heat exchanger. A liquid-vapor separation process is carried out in a separating device, and a liquid obtained in the liquid-vapor separation process is conducted into the heat exchanger as a heating medium.

The invention generally relates to systems and methods for increasing reaction yield. In certain embodiments, the invention provides systems for increasing a yield of a chemical reaction that include a pneumatic sprayer configured to generate a liquid spray discharge from a solvent. The solvent includes a plurality of molecules, a portion of which react with each other within the liquid spray discharge to form a reaction product. The system also includes a collector positioned to receive the liquid spray discharge including the unreacted molecules and the reaction product. The system also includes a recirculation loop connected from the collector to the pneumatic sprayer in order to allow the unreacted molecules and the reaction product to be recycled through the pneumatic sprayer, thereby allowing a plurality of the unreacted molecules to react with each other as the unreacted molecules cycle again through the system.

A multi-waste processing system includes a processing chamber. The processing chamber includes one or more heaters and a piston, and the processing chamber is configured to evaporate liquid waste and compact solid waste input. A condenser is operably connected to the processing chamber. The condenser is configured to condense water from the evaporated liquid waste output from the processing chamber. A gas and water separator is operably connected to the condenser. The gas and water separator is configured to separate water from the evaporated liquid waste output from the processing chamber. A recirculation pathway connects the gas and water separator to the processing chamber to recirculate gas from the gas and water separator to the processing chamber. The piston is actuated to keep the one or more heaters in close proximity to the solid waste and the liquid waste in the processing chamber.

The invention relates to a process for recovering ammonia from an initial aqueous mixture comprising ammonium ions and ammonium salts, the process comprising providing an initial aqueous mixture, desorbing ammonia using humid, heated air to obtain a desorbing liquid phase and a desorbing gas phase, separating the desorbing liquid phase, mixing the desorbing gas phase with a capture gas to obtain a gas mixture, and condensing the gas mixture to obtain a condensate comprising ammonium ions and salt, and an outlet gas. The desorbing liquid phase comprises ammonium ions and ammonium salts in a total concentration of less than 100 ppm. The capture gas comprises carbon dioxide in an amount of at least 50,000 ppm. The total concentration of ammonium ions and ammonium salts in the condensate is higher than the total concentration in the initial aqueous mixture. The invention further relates to a system for performing an ammonium recovery process, a composting system, a composting process and a system for composting and recovering ammonia.

A horizontal sulfur condenser may include an exterior casing with a plurality of condenser tubes arranged longitudinally within the casing, a liquid sulfur reservoir at a longitudinal end within the exterior casing, and an internal baffle that protrudes into the liquid sulfur reservoir from the surface. The lowest of the plurality of condenser tubes is parallel to a wall of the exterior casing. A Claus process gas inlet is proximate a first end of the plurality of condenser tubes, which are arranged horizontally but are positioned vertically above the sulfur reservoir. A liquid sulfur outlet is located at the liquid sulfur surface. The baffle creates multiple chambers above the sulfur reservoir, such as a first chamber defined by the exterior casing and the baffle to receive condensed Claus sulfur in the liquid reservoir, and a second chamber defined by the exterior casing and the baffle to receive degassed liquid sulfur.

An improved system for separating gas from a process stream by providing a stripping unit at the overhead stream of a fractionation column to selectively and effectively remove the gas using a stripping fluid without providing a dedicated light-ends separations unit. The stripper unit may be connected to the reflux drum at the overhead stream. The system for separating gas further achieves greater thermodynamic efficiency by means of a split column design using mechanical vapor recompression with the reboiler and condenser integrated in a falling-film evaporator- or thermosiphon-type vapo-condenser.

A gas condensing device may be configured to condense regeneration gas and separate target gas from condensate. The gas condensing device may include: a housing; a condenser mounted in an upper portion of the housing and configured to condense the regeneration gas; and a reflux apparatus mounted in the housing below the condenser and configured to temporarily store the condensate and discharge evaporation gas evaporated from the condensate back to the condenser.
