Carbon dioxide storage and Transport
Pipelines today operate as a mature market technology and are the most common method for transporting CO2. Gaseous CO2 is typically compressed to a pressure above 8 MPa in order to avoid two-phase flow regimes and increase the density of the CO2.
Captured CO2 could be deliberately injected into the ocean at great depth, where most of it would remain isolated from the atmosphere for centuries.

Objectives
1- Carbon dioxide capture from cement khoms plant using amine-based CO2 capture technology.
2- The overall objective is to evaluate the feasibility of obtaining the heat required for g amine absorption for a particular recovery for a given a set of equipment specifications g and operating conditions from cement plants
3- To develop a model that simulates the removal of CO2 using MEA absorption from cement g plant and design a process of CO2 capture for the cement industry.
4- CO2 absorption process is simulated with commercial ASPEN Plus code and various g g combination of the operating parameters, such as flow rates of flue gas and amine solution, g concentration of amine solution, temperature of absorption.

Conclusion
the using 12.1 mole % of MEA we recovered 97 mol %
The ENRTL model was used in the simulation has a some difficult is found to convergence in the tower.
The capital cost was found highly a cause to the huge quantities of flue gas and to uses compressor to liquefied the co2 by 3 stage
