HDH seawater desalination technology has characteristics of flexible scale, small investment, and suitable for decentralized fresh water demand. This paper designs a system, based on the principles energy conservation mass conservation, theoretical calculation model is established, influence spray liquid flow temperature, airflow, cooling temperature system production Gained output ration (GOR)...

This paper presents a detailed thermodynamical exergy analysis of an optimized MSF distillation plant based on the latest published thermodynamics properties of water and seawater software of the Massachusetts Institute of Technology by using design and optimized plant operation data. Exergy flow rates are evaluated throughout the plant and the exergy flow diagram is prepared in both cases....

This paper applies irreversibility analysis to characterize humidification-dehumidification (HD) desalination cycles and to identify how to further improve cycles and components. It is shown that minimizing specific entropy generation of the cycle maximizes the gained output ratio (GOR). It is also shown that each cycle has one limiting component that cannot be substantially improved and a seco...

This paper presents the analytical investigation of a novel system for combined Dew Point Cooling and Water Recovery (DPC-WR system). The operating principle presented is to utilize dew point cooling phenomenon implemented in two stages order obtain both air water recovery. performance described by different indicators, including coefficient (COP), gained output ratio (GOR), energy utilization ...

First of all, ‘GOR’ should be distinguished from ‘GOR disease’ or ‘pathological GOR’. ‘GOR’ usually refers to an episode of reflux of the gastric contents into the oesophagus. This is a normal phenomenon at all ages. Classifying it as pathological GOR or GOR disease is dependent on the severity as defined by various objective criteria. I infer from the article that the authors implicitly refer ...

This paper presents the analysin ,design and implementation of a high voltage ratio topology of DC-DC converter. The DC-DC converter has high voltage ratio with reduced input current, output voltage and output current ripple, and also reduces the voltage and current rating of power electronics components and compared with conventional boost converter. The voltage stress on the switches are  red...

Due to the lack of natural water resources and high consumption in industries, desalination systems are good options supply demands, especially regions with a crisis. If these wastes used thermal cycles, addition improving efficiency reducing energy consumption, production environmental pollutants can also be reduced. In this paper, multi-stage flash brine recirculation (MSF-BR) system Abadan r...

In an oil field that has reached its maximum gas handling capacity, and where wells are producing under gas coning conditions such that the gas-oil ratio (GOR) depends on the wells production rate, oil production is maximized if the marginal GOR (mGOR) is equal for all wells. The GOR and the mGOR are not readily available measurements, but they can be predicted using detailed reservoir models. ...

A comprehensive study was conducted to elucidate the effect of operating conditions on performance a multi-effect vacuum membrane distillation pilot plant. theoretical assessment energy and exergy efficiency process achieved using mathematical model based heat mass transfer, which calibrated experimental data obtained from The plant solar (V-MEMD) module comprising five stages. It found that ma...

In this study, a novel integrated forward osmosis - membrane distillation (FO-MD) module equipped with an isolation barrier carefully placed between the FO and MD membranes is experimentally investigated, its performance compared conventional hybrid module. The function of to osmotically thermally separate draw solution (DS) feed channels. A systematic approach adopted compare flux through both...
