Abstract

Natural gas processing is a very important field that is of great significance due to increasing demand for energy as well as separation of gas mixtures. Most of the natural gas produced in the world is coproduced with acid gases such as CO2 which need to be removed to increase the caloric value of natural gas. The contaminants in natural gas are also need to be removed so that the natural gas will be an end product that is safe to be used by consumer. Thus, a comprehensive review of research efforts in CO2 separation from natural gas is required to capture details of the current scientific and technological progresses on the development of Cryogenic system with better separation performance and more cost saving. A simulation has been done for this project in order to see the performance of a gas separation system by using ASPEN HYSYS software. The simulation of 70% CO2 feed concentration at feed condition 50 barg and -25°C was done and at these conditions the percentage separation of the gas was found to be 98.48% of methane and 1.52% of CO2 in the top product. The analysis proves that the proposed system can efficiently recover CO2 from mixed gases, regardless of initial compositions as the CO2 purity in the product could be as high as 99.9% under various circumstances. Results obtained from the model in this project has satisfied the requirement of LNG Specification and it is believed that this project will serve as a good reference for future work in design and development of gas separation equipment
