PROJECT ABSTRACT

Project Title :

Modelation and Simulation of the absorption process of CO2 in amine/alkaline solution

Description :

³The Earth¶s climate system has demonstrably changed on both global and regional scales since the pre -industrial era, with some of these changes attributable to human activities´ -  IPCC 2007 [1]. Reducing the

greenhouse gas emissions (mainly CO 2) is very important and actual issue. To stabilize atmospheric levels of 

greenhouse gases, mitigation technologies must be developed.

³Absorption is the most common technology for CO 2 removal today and one of the few viable options for large CO2 removal´ ± Desideri and Corbelli [2].

  An important point of this technology is the possibility of applying to existing plants. This technology isestablished but need to be improved for efficient utilization of energy reserves in the actual context of human

society development. Possibility of use of new solvents or process design modifications are intensely studied

to reduce the cost of separation and to increase the energy efficiency.Computer-based process simulations are today recognized as an essential tool in c hemical process

industries. A mathematical model is necessary to describe closer the real physical ± chemical processes that

take place in a reactor (absorber column).

In this paper, dynamic modeling and simulation of the absorption process of CO2 in amin e /alkaline solutionwas studied. A mathematical model was developed for analyzing absorption rate and understanding of micro

level interaction of various processes going inside de reactor.

The modeling includes transfer processes: mass and heat to study the coupled effect of temperature and

concentration on the rate of absorption.

 The reaction kinetics and the vapor-liquid equilibrium (VLE) are other important parts of the model. The

developed equations include both ordinary differential equations and partial differential equation. The

discretization was used to transform partial differential equations in ordinary ones.

The dynamic mathematical model was solved using Matlab software package.The evolutions (in time and space) of the processes paramet ers (liquid and gaseous flows, composition of 

the streams, temperatures) were studied during CO 2 absorption process. To validate the model developed ,

the simulation results were compared with experimental data and a ChemCad model simulation. From the

comparison, one can observe a close similarity between simulation results and data co llected fromlaboratory. This fact validates the application developed for simulation of the process and proves the utility of 

the model in analyzing and optimization CO2 absorption process, using amine/alkaline solution.
