Distillation is an essential separation process in the chemical and petrochemical industry. The distillation process is a highly nonlinear, complex, interactive and non -stationary, therefore its control is difficult. In the present work an adaptive neuro-fuzzy controller is designed to control a binary distillation process. A conventional PID controller is also designed for comparison purpose....

Distillation is a widely used separation method in the process industries and it is the largest energy consumer among individual process units. Improvement of energy efficiency in distillation systems is still an active research field. Among the issues concerned with the improvement of energy efficiency of distillation systems, the optimal design and synthesis A SHORT Note ABOUT ENERGY-EFFICIEN...

0 Fluoride contamination occurs in a wide range of industrial effluents-wastewater from aluminum and steel production, metal finishing and electroplating, glass and semiconductor manufacturing, ore-beneficiation, and fertilizer operations. Concentration limits for fluoride of 1.0 to 1.5 mg/L have been established from time to time for surface waters, based upon two premises: (1) that these wate...

Invariant rectifying and stripping (IRS) curves are used for thermodynamic analysis of a distillation column. Thermal integration of a distillation column with the background process through side exchangers (side reboilers/condensers) is important for energy-efficient design of a distillation column. Thermal integration of a distillation column through side exchangers also improves the exergeti...

This paper proposes the simultaneous integration of environmentally benign solvent selection (chemical synthesis), solvent recycling (process synthesis) and optimal control for the separation of azeotropic systems using batch distillation. The previous work performed by Kim et al. (2004) combines the chemical synthesis and process synthesis under uncertainty. For batch distillation, optimal ope...

Hydro-Distillation (HD), Cold Pressing (CP) and Microwave Clevenger or microwave Accelerated Distillation (MAD) methods have been compared and evaluated for their efficiency in the extraction of essential oil (EO) from fresh Citrus peels. EO from peel of 4 varieties of Algerian sweet orange (C. sinensis), Lemons (C. limon), Citrons (C. medica), sour orange (C. aurantium), grapefruits (C. paradi...

RESUMO – This work aimed the evaluation of a saline extractive distillation for the ethanol production. Unlike the current method of dehydration of ethanol, which uses a solvent, distillation with the use of salt does not include problems related to toxicity and has lower power consumption, since salt is not volatilized within the distillation column. Many salts had been tested like calcium chl...

This paper is concerned with the computer-aided optimal design of reaction-distillation processes. The production of solvent 2,3-dimethylbutene-1 by isomerization of 2,3dimethylbutene-2 is considered as an innovative benchmark problem. Possible process candidates are a reactive distillation column, a reactor coupled to a nonreactive distillation column or a reactive reboiler with a nonreactive ...
