Ethanol is largely used as a solvent in the synthesis of varnishes and perfumes. It is also used as a preservative for biological products, fuel, and gasoline additives. Anethanol-water mixture, normally obtained by fractional distillation</span...

Electricity–water cogeneration power plants are an important tool for advancing sustainable water treatment technologies because they provide a cost-effective and environmentally friendly solution meeting the energy needs of communities. By integrating production, these can reduce carbon emissions help mitigate impact climate change. This work deals with exergy analysis plant electrical generat...

Powering thermal desalination technologies by renewable energy is believed to be a viable solution overcome the worldwide freshwater scarcity problem without causing more damage environment. In this paper, multi-effect distillation system (MED) with mechanical vapor compression powered generated electrical power of photovoltaic/thermal collectors and assisted by-product generated. The sized acc...

Desalination technologies improve water quality, greatly reduce water shortage problems, and improve quality of life and economic status. Two main technologies are currently used in water desalination: thermal (phase-change) processes and membrane processes. The primary thermal distillation processes include multistage flash distillation (MSF), multi-effect distillation (MED), and vapor compres...

In this paper, the experimental design and computer simulation model of a multi-effect humidification/dehumidification (MEH) solar desalination system has been presented. The pilot plant on MEH was designed, fabricated and tested at the Center for Energy Studies, Indian Institute of Technology Delhi, India. The heat collection part has been designed to provide continuously the hot water to the ...

Background and objectives: It is necessary to specify the best conditions of essential oils production to get more major compound(s) and higher yield oil. The fennel oil is useful in pharmaceutical industry as flavor. The main component of fennel oil is anethole (55-75%). The objective of this work was to identify the effect of  particle size, pH of water, method of distillatio...

the understanding of the dynamic behavior of distillation columns has received considerable attention because distillation is one of the most widely used unit operations in chemical process industries. this paper reports a dynamic simulation study of the possible distillation columns sequences of dew pointing unit in the second phase of south pars gas refinery. in this unit, three columns are u...
