New column configurations for pressure swing batch distillation II. Rigorous simulation calculations [PDF]
, 2007 The pressure swing distillation in different batch column configurations is investigated by rigorous simulation calculations. The calculations are made by a professional flow-sheet simulator for the separation of a minimum (ethanol–toluene) and a ...

Membrane-assisted Cryogenic Distillation for Energy-efficient Argon Production from Air
Chemical Engineering Transactions, 2018 High-purity argon is produced from air by cryogenic distillation; the process is energy intensive because of the similar volatilities of oxygen and argon.

Hydrodynamic and mass transfer efficiency of ceramic foam packing applied to distillation. [PDF]
, 2009 In addition to a high void volume and specific area, solid foams possess other properties (low density, good thermal, mechanical, electrical, and acoustical behaviour) that make them attractive for applications such as heat exchangers and reformers ...

Generalised model for heteroazeotropic batch distillation with variable decanter hold-up [PDF]
, 2013 A general model of batch heteroazeotropic distillation is proposed. Both liquid phases present in the decanter can be refluxed or withdrawn as distillate, their hold-up can be increased, decreased or kept constant, as well. By assuming maximal separation,

A New Approach to the Identification of Distillation Column Based on Hammerstein Model
Modelling and Simulation in Engineering, 2014 Developing a suitable nonlinear model is the most challenging problem in the application of nonlinear model based controllers to distillation column. Hammerstein model consists of a nonlinear static element described by wavenet based nonlinear function ...
