A heat-integrated prefractionator arrangement is studied for a ternary separation of a propane–butane–pentane mixture. These types of integrated prefractionator arrangements have large energy savings compared with the best of the direct or indirect sequence with no heat integration. However, a heat-integrated distillation system can be more difficult to control than a non-integrated arrangement...

This paper projected fuzzy logic control based intention has been protruded for a methanol water arrangement of bubble cap distillation column. In this distillation column is extremely nonlinear and conventional control is controlling the composition is a difficult task. Fuzzy inference system (FIS) and fuzzy rule based system (FRBS) is designed to govern the manipulate variable (reflux ratio) ...

Methyl valerate (VAME), also known as methyl pentanoate, is the methyl ester of the pentanoic acid (valeric acid). VAME is usually used as fragrance in the production of beauty care, soap and laundry detergents. High purity of VAME can also be used as plasticizer. This study presents the design details of the process for the manufacture of VAME. Reactive distillation column (RDC) is used in the...

Design and analysis of distillation columns usually takes place by using rigorous equilibrium models, where efficiencies are utilized to enhance the designs obtained and have a better approach to the real performance of the column. A second alternative, based on the mass and heat transfer rates, has been proposed and it is known as the non-equilibrium (or rate-based) model. By employing this ap...
