Modelling and optimisation of industrial absorption processes: An EC collaborative research project (original) (raw)

Industrial Absorption – Current Status and Future Aspects

Absorption is still one of the most important separation processes in chemical and petrochemical industry. Although absorption has reached a high level in theoretical understanding, process design and technical implementation, nowadays industrial work on this unit operation is full of economical, technical and scientific challenges. The current status and future developments of industrial absorption are described in this presentation.

Economic analyses of absorption systems: Part A—Design and cost evaluation

Energy Conversion and Management, 1997

Economic analyses of absorption system components have been conducted with the aim to optimize the various operating parameters. The absorber, condenser, evaporator, generator, rectifier, precooler and preheater have been designed using standard procedures, and their costs have been estimated based upon the materials used, fabrication installation and overhead charges. Four types of refrigerant-absorbent combinations (H2O-LiBr, NH3-H2O, NH3-NaSCN and NH3-LiNO3) using

Computational design applied to equilibrium-staged and rate-based absorption processes

Revista De Chimie, 2020

Simulators are of great interest in Chemical Engineering because they facilitate process optimization and help evaluate different solutions through the so-called “what-if” approach. They include the most advanced thermodynamical models and complete libraries for the calculation of physicochemical properties and estimation of phase equilibria data which are successfully integrated in the process design. Moreover, simulators allow addressing both stationary and batch operations. For this reason, their use in the design of Industrial Chemistry processes has gained much acceptance in the last decades. Even so, simulations should be accompanied by another computational tool which allows the professionals to implement specific algorithms which relate inputs and outputs, so as to get the most out of the computing power. We herein exemplify how Aspen Plus and Mathcad Prime software packages were successfully integrated in a case study on the removal of carbon disulphide by contact with a pa...
