Thermodynamics Analysis of a Membrane Distillation Crystallization Ion Recovery System for Hydroponic Greenhouses Assisted with Renewable Energy

Sustaining agricultural demands is a typical problem, particularly in locations afflicted by the scarcity of fresh water, poor farming soil, and hot weather. The main goal this study to perform thermodynamic analysis an integrated multigeneration system containing direct contact membrane distillation crystallization that recovers beneficial hydroponic nutrients from seawater using renewable energy resources. A parametric carried out determine impacts various factors on system, such as changing rate mass flow rate, recovery ratio, salinity. This proposes novel sustainable for desalination ions provide solution greenhouse ventilation dual evaporator vapor compression refrigeration system. With overall exergy efficiency 41.40%, 39.80%, respectively, requires about 1182.69 kW 5314.6 electrical thermal power total, desalinate 5 kg/s recover 170 mg/s Sulfate (SO4), 81.28 Magnesium (Mg), 25.48 Calcium (Ca), 24.16 Potassium (K), yielding 4.4 solution, ventilating 25 greenhouses with volume 600 m3 single greenhouse.
