The present disclosure generally relates to systems and methods for ammonia purification. More particularly, the systems and methods use a unique arrangement of a caustic wash, a water wash, an ammonia stripper and a caustic fractionator to recover ammonia otherwise lost during conventional purification.

Disclosed herein are advantageous phase separator devices, and related methods of fabrication and use thereof. The present disclosure provides improved phase separator devices for phase separation of feedstreams, and improved systems/methods for utilizing and fabricating the phase separator devices. More particularly, the present disclosure provides porous (e.g., three-dimensional gradient porous) phase separator devices for phase separation of fluid mixtures (e.g., to separate a two-phase fluid mixture) to a first fluid phase flow (e.g., to a liquid flow) and to a second fluid phase flow (e.g., to a gas flow). At least a portion of the phase separator devices of the present disclosure can be fabricated via machining, powder metallurgy (e.g., sintering), and/or produced utilizing additive manufacturing techniques.

Provided is an ammonia stripping device, and a resource recovery type high concentration wastewater treatment system using the ammonia stripping device. The ammonia stripping device optimizes the conditions of pH, temperature, and pressure within a decompression type reactor with respect to raw water resulting from gathering high concentration wastewater and removing a solid therefrom and causes the stripped ammonia to be highly purified in a gas phase without phase change by a separation membrane process of causing the stripped ammonia to pass through a gas separation membrane, and selectively recovering the recovered ammonia. The recovered ammonia of high purity can be reused in being made into resources such as production of urea solutions, power generation by raw materials of green hydrogen and mixed fuel, and so on.
