摘要： A new and innovative power and treated water co-generation system is provided that includes a modified Kalina cycle and a forward osmosis (FO) membrane. The Kalina cycle of the provided system is used for power production, whereas the system's FO process is used for water production. The provided system modifies a typical Kalina cycle to include a more efficient and relatively low-temperature heat source, while still utilizing the same working fluid, which is ammonia-water. The draw solution for the provided system's FO process is also ammonia-water, which is known and efficient for desalination and wastewater treatment. In some aspects, the working fluid of the system may be a specific ammonia-water composition including between 30-95% ammonia. The presently disclosed system combines the Kalina process and the FO process into an improved and innovative heat integration system to minimize energy requirements and enable operation at both small and large scales.

摘要： A method and an apparatus for recovery and deep treatment of a polluted acid. The method comprises the following main steps: (1) selectively adsorbing rare and noble metals, such as rhenium, selenium and the like; (2) separating copper from arsenic to recover the copper; (3) carrying out efficient vulcanization to perform deep arsenic removal; (4) carrying out electrodialysis to pre-concentrate acid; (5) evaporating and concentrating the acid; (6) carrying out an air-stripping method to remove fluorine and chlorine. The polluted acid treatment apparatus mainly comprises a precision filtering tank, a special adsorbing tank, a copper-arsenic separation device, a vulcanization device, an electrodialysis device, an evaporative concentration device, and an air-stripping device. The method and the apparatus can implement efficient recovery of valuable elements in polluted acid wastewater and separate treatment harmful elements, has obvious economical, social and environmental benefits, and has wide application prospects.

摘要： This disclosure provides water processing apparatuses, systems, and methods for recovering purified water and concentrated brine from wastewater. The water processing apparatuses, systems, and methods utilize ionomer membrane technology to separate water vapor from volatiles of a wastewater stream. The wastewater stream is evaporated into a gas stream including water vapor and volatiles of the wastewater stream in an evaporation container. The gas stream is delivered to a water separation module spatially separated from and fluidly coupled to the evaporation container. The water vapor of the gas stream is separated out in the water separation module while the volatiles are rejected. The water vapor can be collected into purified water while concentrated brine from the wastewater stream is left behind in the evaporation container.

摘要： Systems and processes for reducing the energy requirements of an ammonia recovery stripper in a chilled ammonia-based CO2 removal system. The systems and processes include a nanofiltration or reverse osmosis unit for physically separating the washed liquid from a wash vessel configured to receive an ammonia slip feed stream from the main absorber of the chilled ammonia-based CO2 removal system and provide first and second feed streams. Relative to the washed liquid from the wash vessel, the first feed stream has a decreased ammonia molarity whereas the second feed stream has an increased ammonia molarity. The second feed stream is then fed to the ammonia recovery stripper, which reduces steam consumption. The reduced steam consumption translates to significant energy savings, among numerous other advantages. Additionally, the systems and process provide a reduction of equipment sizes related to the stripper unit as may be desired in some applications.

摘要： Producing a dealcoholized beverage from its alcoholic beverage starting product and plant for implementing the method, which comprises the following steps: separating the beverage starting product into an alcoholic and aromatic permeate and into an aromatic and almost alcohol-free retentate in a permeation module by non-thermal permeation, dealcoholizing the permeate in a module intended for that task, and finally mixing the dealcoholized permeate with the almost alcohol-free retentate in a final-mixing module. Prior to the dealcoholizing, aroma compounds are removed from the aromatic and alcoholic permeate by cold adsorption in an aroma adsorber, resulting both in an aroma phase and in an aroma-free but alcoholic permeate which, however, has the alcohol removed from it by alcohol separation, resulting in an aqueous, largely dearomatized and dealcoholized permeate water phase. Final mixing of aroma phase, permeate water phase and retentate takes place in the final-mixing module to give a dealcoholized beverage.
