Abstract:

World natural gas demand has been increasing constantly and will continue to do so in the coming years. Before storing or sending the natural gas to pipelines, it is essential to remove impurities such as CO2 from the raw natural gas. Removing CO2 will raise the heating value of natural gas, decrease or prevent the pipeline corrosion, and reduce the transported gases volume. The application of membrane technology in this area to replace conventional methods such as amine absorption is growing very fast. The advantages of membrane technology are mostly related to its low operating and maintenance cost. Recently, polymer of intrinsic microporosity PIM-1 has become a potential material for CO2 removal in membrane technology due to its attractive performance. However, PIM-1 membranes suffer from a decrease in permeability over time (aging), which is common to all glassy polymers, and hampers its use in commercial applications. Metal organic frameworks (MOFs) have been proven to be good fillers in polymer matrices due to their large surface area, high pore volume, high adsorption capacity and high structural controllability with very good stability. UiO-66 is an MOF based on zirconium metal that shows a good thermal stability up to 540°C. It also has high affinity towards CO2 due to the existence of the hydroxyl group in its structure. In addition, graphene oxide (GO) has emerged recently as a filler material for gas separation membranes; the presence of hydroxylic and carboxylic groups in GO coupled with a high surface area and a good interaction with polymers has led to the preparation of improved membrane for CO2 separation. The aim of this work is to investigate the effect of adding a combination of UiO-66 and GO fillers into PIM-1 matrices to improve the polymer stability and increase the membrane performance.

Biography :

Ahmed Waleed Ameen has experience in membrane science and gas separation process. In 2013, he got his bachelor degree in chemical engineering from the University of Leeds graduated with a first class degree. After that, he joined the Research and Development Center Department in Saudi Aramco. He had one and half year experience in the membrane lab contributing to several projects focusing on applying membranes in natural gas separation applications. He had one year assignment in Berri gas plant and worked as a process engineer in the gas absorption unit and then in the sulfur recovery unit. He then returned to the membrane team in the research center focusing in membrane process simulation and also contributed in testing the commercial membranes in the membrane pilot plant. Currently, He is a Master student at the University of Manchester under Dr. Patricia Gorgojo supervision.
