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 ...

dry areas near the sea can obtain fresh water through solar distillation of saline sea water resources. however, these solar distillation sites produce wastewater as a result of desalination of sea water with high salt concentration. waste must be disposed of with the least effect on the receiving environment (sea, in most cases). initial dilution and its characteristics play important roles in...

Sneesby et al. recently suggested that adding trays in the stripping and rectifying sections of a reacti®e distillation column can degrade performance. This effect, if true, is not only counterintuiti®e, but ®ery disturbing because it suggests that the design of reacti®e distillation columns cannot use conser®ati®e estimates of tray numbers, that is, we cannot simply add excess trays, as in con...

The simulation and steady state operation of a vapor recompression pilot plant distillation column is studied in order to improve the thermal efficiency. A binary system of ethanol-water mixture is used. The simulation is carried through ASPEN PLUS version 9.3-1. Energy reduction of 89.26% is obtained comparing to the conventional distillation and the thermodynamic efficiency is improved from 1...

the equation of state soave-redlich-kwong (srk) and its modification (predictive srk or psrk) are applied to simulate multicomponet distillation, which separate main component of spearmint essential oil. the simulation model is based on bubble point method, and the wang-henke algorithm. spearmint essential oil is considered in the study and the original experimental data were obtained from pilo...

This paper describes BUPT (pris) participation in faceted blog distillation task at Blog Track 2009. The system adopts a two-stage strategy in faceted blog distillation task. In the first stage, the system carries out a basic topic relevance retrieval to get the top k blogs for each query. In the second stage, different models are designed to judge the facets and ranking.

Detailed chemical process simulations are a useful tool in designing and optimizing complex systems and architectures for human life support. Dynamic and steady-state models of these systems help contrast the interactions of various operating parameters and hardware designs, which become extremely useful in trade-study analyses. NASA’s Exploration Life Support technology development project rec...

Previously, Tanskanen and Pohjola (2000) and Tanskanen and Malinen (2005) have presented a method of rigorous minimum energy calculation for non-ideal multicomponent distillation. The method is based on column simulation with a large number of equilibrium stages to mimic infinitely high columns, and it has been successfully tested with simple distillation column systems. This paper describes a ...

This paper presents the system adopted for the Faceted Blog Distillation task by PRIS team. The PRIS system is submitted by Pattern Recognition and Intelligent System Lab at Beijing University of Posts and Telecommunications. And a two-stage strategy is involved for this task. First, an adaptable Voting Model is carried out for blog distillation. Then, different models are designed to judge the...
