Hybrid Membrane-Distillation Separation Processes [PDF]
Chemical Engineering Transactions, 2014 A novel synthesis approach is developed to evaluate and optimise various hybrid membrane-distillation schemes. The problem is formulated as an optimisation problem, where the objective is to minimise the total operating cost of the separation scheme ...

New double column system for heteroazeotropic batch distillation [PDF]
, 2009 A new double column system (DCS) operated in closed mode is suggested for heterogeneous batch distillation. This configuration is investigated by feasibility studies based on the assumption of maximal separation and is compared with the traditional batch

APPLICATION OF MODEL PREDICTIVE CONTROL (MPC) TUNING STRATEGY IN MULTIVARIABLE CONTROL OF DISTILLATION COLUMN [PDF]
, 2007 A model predictive control strategy is proposed for multivariable nonlinear control problem in a distillation column. The aim is to provide a solution to nonlinear control problem that is favorable in terms of industrial implementation.

Dynamics and control of unstable distillation columns [PDF]
Modeling, Identification and Control: A Norwegian Research Bulletin, 1992 The fact that ideal two-product distillation columns may have multiple steady states and unstable operating points has only recently been recognized. This paper discusses the dynamics and control implications. It is shown that columns operating with reflux and boilup as independent variables become unstable if the internal flows are sufficiently large.

Numerical study of a Solar Absorption Refrigeration Machine [PDF]
E3S Web of Conferences, 2020 In this paper, we present a numerical study of a single-stage absorption refrigeration machine, operating with a couple of water-ammonia fluids, equipped with a distillation column and associated with a solar heating system using solar collectors.

Flexibility for Absorption and Distillation Columns
Chemical Engineering Transactions, 2018 The flexibility of absorption and distillation columns is limited by macroscopic fluid dynamic phenomena like flooding, entrainment, weeping or dewetting. The design of those columns is a crucial task and depends on the separation task, the needed capacity and the fluid dynamic boundaries.

A Heuristic for Extractive Agent Flow Rate in Extractive Distillation
Chemical Engineering Transactions, 2018 Distillation is the most widely used separation process for liquids separation in the industry. Even when the volatilities of the mixture are not favorable, then enhanced distillation is used.

New extractive configuration separating azeotropic mixture in semi-batch way [PDF]
, 2006 A new variant of batch extractive distillation, the so-called inverse-fed batch extractive distillation is presented. The total amount of the entrainer is pre-loaded to the boiler, and the mixture charge to be separated is continuously fed to the column ...
