Work History

research on Improved carbon sequestration in aquifers

The university of manchester

March 2011 - March 2011

Improved Carbon Sequestration in Saline Aquifers:

Build models for different trapping mechanisms such as solubility trapping, residual gas trapping and mineral trapping, then optimize for the best model that could store the maximum amount of CO2 at optimal operating conditions for low and high permeability aquifers.

Secondly to show how these modelling techniques are used to simulate for the optimal location of the well and operating conditions for both with and without injection of water. But in this research both solubility and residual gas saturation are calculated simultaneously by the simulation software eclipse300 to give a single total gas saturation that gives information about the total trapped gas in the aquifer.

Further different solubility models are studied and analysed to see which model can be optimized to store the maximum amount of CO2 by conducting an uncertainty analysis for different parameters.

Sensitivity analysis is also done to find out the average pore pressure or the bottom hole pressure that would be safe enough to have in the aquifer using geomechanical techniques.

Finally optimization for leakage potential with and without faults in the model is done and the gas saturation behaviour is observed for maximum storage of CO2.

The main goal of this research is to observe how far the uncertainty parameters affect the storage performance of this particular model. Using this approach one can represent the model in the better way with the heterogeneity properties of the rock in the aquifer. Finally by observing the uncertainty parameters in the models that actually affect the rate of gas injection and other operating conditions, one can raise the issues about the storage of CO2.

Feasibility study of improving an existing hydrogen network

The University of Mnachester

April 2011 - May 2011

• Determined the minimum theoretical hydrogen production from the hydrogen plant.
• Suggested network modifications that can improve the existing system performance economically.
• Considering the HC throughput will be increased by 50%, as it is expensive to revamp the hydrogen plant, it is suggested to add a pressure swing adsorber (PSA) into the network to recover hydrogen. Developed a configuration with PSA to satisfy the future H2 demand optimally
• Evaluate few piping modifications to the existing network.

Evaluation of a new design of a steam system in a refinery

The University of Manchester

March 2011 - April 2011

• Replicated a design using STAR software to calculate the operating cost of the given refinery system.
• Under the same system configuration found out whether the designed operation could be improved for different cases in order to reduce the operating cost.
• Using FCC as an example examined the system flexibility to cope with periodical unit maintenance.
• Suggested possible modifications to the design to improve the energy efficiency without too much additional capital investment, especially regarding the issues of system configuration and driver selection.

Evaluation of heat recovery potentials in a crude oil distillation unit

The University of Manchester

February 2011 - March 2011

• Used the pinch analysis technique to identify the ideal maximum furnace inlet temperature if the capital cost is disregarded, and calculated the amount of energy to be saved if the basic design can be improved to the ideal position.
• Designed a heat exchanger network that can reach or get close to the ideal furnace inlet temperature and also evaluated an alternative network design to obtain the best inlet furnace target temperature.
• Discussed any other potential improvements in the distillation unit design that could help to improve the energy efficiency further.
