Abstract: The present invention relates to processes and systems for ammonia recovery and/or acid-gas separation. In some embodiments, a system for acid gas separation may be integrated with an ammonia abatement cycle employing a high temperature absorber. In some embodiments, a system for acid gas separation may employ a higher temperature absorber due to the lower energy consumption and cost of the integrated ammonia abatement cycle. Advantageously, heat may be recovered from the absorber to power at least a portion of any acid gas desorption in the process. Reverse osmosis or other membranes may be employed.

Abstract: The invention pertains to processes for separating water from air. The processes may employ using an LCST solution with or without subsequent reverse osmosis, nanofiltration, or ultrafiltration.

Abstract: The present invention pertains to systems, methods, and compositions for liquid phase change, including for active cloud point, e.g., critical solution temperature, adjustment and heating or cooling, e.g., refrigeration, cycles. In some embodiments heat is absorbed, released or both due to phase changes in a liquid system. Advantageously, the phase changes may be controlled by controlling the ingredients or amounts of certain components of the liquid system. Advantages may include lower capital expenditures, lower operating expenses, or both for a diverse and wide range of heating and cooling applications. Such applications include, for example, cooling of data centers, cooled transportation of goods, refrigeration, heat pumps, extractions, ocean thermal energy conversion, and de-icing of roads to name just a few.

Abstract: The present application pertains to systems and methods for storing and generating power. In one embodiment the system pertains to a first storage reservoir near the surface of a body of water and configured to store a fluid which has a lower density than water. A second storage reservoir is located below the surface of the body of water and configured to store a fluid which has a higher density than water. A pump, generator, and the first and second reservoir are operatively connected such that power is stored by displacing the fluid which has a higher density than water in the second storage reservoir by pumping the fluid which has a lower density than water in the first storage reservoir to the second storage reservoir. Power is generated or discharged by allowing the fluid which has a lower density than water in the second storage reservoir to return to the first storage reservoir. The fluid which has a higher density than water may be in liquid form.
