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 ...

Ethanol production from agro-based raw materials normally involves two major steps, fermentation and distillation. These steps are reviewed, mainly in relation to molasses, which is the most common raw material in tropical countries. The specific effect on fermentation efficiency of molasses quality in terms Fermentable Sugars, the ratio of fermentable to non-fermentable solids, Volatile Acids,...

The minimum energy requirements of six different heat-integrated multi-effect and three non-integrated distillation arrangements for separating a ternary mixture have been considered. The focus of the paper is on a heat-integrated complex distillation configuration; called a multi-effect prefractionator arrangement. The comparison of the different arrangements is based on the minimum vapour flo...

A new absorption vapor compression distillation was proposed in present research. An open absorption heat transformer has a coupled thermally evaporator and absorber. Distillation of waste water with high content of SiO 2 from heavy oil production. The waste heat of 70 C can be elevated up to 125 C and generate steam of 120 C. The waste heat is able to drive four-effect distillation to produce ...

this article deals with the issues associated with developing a new design methodology for the nonlinear model-predictive control (mpc) of a chemical plant. a combination of multiple neural networks is selected and used to model a nonlinear multi-input multi-output (mimo) process with time delays.  an optimization procedure for a neural mpc algorithm based on this model is then developed. the p...

An industrial separation system consisting of four pressure-staged distillation columns has been studied to see if multi-effect integration can be applied to any two columns in the sequence. Shortcut equations and Vmin-diagrams have been used for screening purposes to find the columns with the highest potential for energy savings. The most promising case has then been further studied using rigo...
