Characterization of Membranes for Advanced Direct Carbon Capture

Hashim I.A., Ogunlude P., Ogoun E., Abunumah O., Aisueni F., Ramalan M., Gobina E., Robert Godon University, UK

Carbon capture is essential for lowering anthropogenic carbon emissions and, as a result, limiting global warming. Membrane technology has a lot of potential for extremely efficient carbon capture because of its energy-efficient and environmentally friendly [...]

Development of dense membranes for high-density hydrogen production from ammonia catalytic decomposition (cracking) for PEM fuel cells power in Long-haul Passenger Aircraft Transportation

Gobina E., Robert Gordon University, UK

Aviation is a major greenhouse gas contributor responsible for around 3.2% of global CO2 emissions to the atmosphere. That corresponds to over than 1 billion metric tons of carbon (A metric ton is a little [...]

Using Nanoporous Core-Samples to Mimic the Effect of Petrophysical Parameters on Natural Gas Flowrate in an Unconventional Gas Reservoir

Ogoun E., Abunumah O., Aisueni F., Gobina E., Robert Gordon University, UK

This work adopts ceramic core technology, which has gained significant attention over the last decades, to enable laboratory study of the permeation of gases continuously under mild conditions and under realistic pressure drops with very [...]

Direct Oxygen Air Capture Using Pressure-Driven Ion Transport Membranes: Membrane Support Evaluation

Antwi S., Giwa A., Gobina E., Robert Gordon University, UK

In the chemical and medical fields, oxygen-enriched air plays a vital role in their operation. Commercial production of oxygen-enriched air is achieved by cryogenic distillation and pressure swing adsorption, respectively. The function of these two [...]

Effect of pore size and Porosity on Contact angle of Ceramic membrane for Oil-in-water Emulsion Separation

Aisueni F., Gobina E., Prabhu R., Robert Gordon University, UK

The main objective of this work is to study the effect of pore size and porosity on contact angle of ceramic membrane for Oil-in-water emulsion separation. This would include using N2 adsorption/desorption to validate pore [...]

The Quantitative Effect of Flow Direction on Gas Permeation in Ceramic Membrane

Ramala M.M., Abunumah O., Gobina E., Robert Gordon University, UK

The effect of flow direction in porous ceramic membrane has been extensively studied. Understanding fluid flow through membrane has offered utility to a number of industrial processes such as gas separation, catalytic reactions, enhanced oil [...]

Experimental Determination of Carbon Capture and Sequestration Response to Reservoir Quantities

Abunumah O., Ogunlude P., Gobina E., Centre for Process Integration and Membrane Technology, School of Engineering, The Robert Gordon University, Aberdeen, UK

Reservoir entities can be classified into geological, geometrical and fluidic. To complicate matters, reservoirs are usually set in geological layers, such that each layer interacts with injected and resident fluids differently. Carbon dioxide (CO2) is [...]
