Process simulation of integrated biohydrogen production: hydrogen recovery by membrane separation

Biohydrogen - the Microbiological Production of Hydrogen Fuel

Simulation of a membrane air separation unit using industrial process simulators

Nowadays, membrane processes are widely used for high purity Nitrogen production. Separation of air by membranes is a flexible process in which the investment and operational costs are lower than for example adsorption or cryogenic processes. Such processes are based on relative permeability of air components which are transported by the pressure difference between two sides of the membrane. M...

An Integrated Membrane Process for Butenes Production

Iso-butene is an important material for the production of chemicals and polymers. It can take part in various chemical reactions, such as hydrogenation, oxidation and other additions owing to the presence of a reactive double bond. It is usually obtained as a by-product of a petroleum refinery, by Fluidized Catalytic Cracking (FCC) of naphtha or gas-oil. However, an interesting alternative to i...

Control System Development for Integrated Bioreactor and Membrane Separation Process

A bioreactor integrated with an electrically driven membrane separation process (Reverse Electro-Enhanced Dialysis REED) is under investigation as potential technology for enhancing lactic acid bioproduction. In order reveal the operation of the integrated process to achieve a specific production goal, a methodology for goal driven control system development is expanded to handle periodically o...

Mathematical Modeling of Gas Separation Process with Flat Carbon Membrane

Carbon molecular sieve membranes (CMSMs) have been considered as very promising candidates for gas separation, in terms of separation properties as well as thermal and chemical stability. Due to the numerous advantages and wide applications of carbon membranes, their application for gas separation is of special importance. Because of the importance of carbon membranes and a large number of stud...
