Hasan’s funded project, “Modular Process Intensification of Methane Separation, Storage and Conversion,” could potentially open up large swaths of resources currently not being used in these industries.
Currently there are many different natural gas sources that are not being utilized, such as stranded natural gas, associated gas, distributed shale gas, landfill gas, biogas and fuel gas, to name a few. These gas sources are often small, regionally distributed and unused for a number of different reasons, all related to cost benefit. In most cases, these gases are just flared to avoid operational and environmental consequences. They often contain impurities at widely different concentrations, and the overall composition of these resources varies from source to source. Using the traditional method of transporting the raw gas through a pipeline to a distant processing plant is a significant investment, one that does not make financial sense for the quantities of gasses at these disparate sources.
Hasan’s research will use advanced process intensification methods, optimization theory and algorithms to discover modular technologies that will turn this problem into opportunity. Specifically, Hasan will employ a novel process intensification method developed in his research group that combines multiple operations into a single multifunctional unit. The goal is to develop modular technology that achieves the same performance of all of the processes that normally take place at a gas processing and conversion plant using less equipment. In this particular case, converting methane and/or other natural gasses into hydrogen, the raw gas has to be treated many different times using many different processes before it is converted into pure hydrogen. Hasan hopes to combine all of these different processes into one multifunctional gas technology.
“You don’t want to have a huge pipeline connecting all of these different gas sources, that is a huge investment that does not make sense,” said Hasan. “The solution is to go to these sources, not just to collect the gas, but to produce chemicals on-site.”
While modular process intensification is not a new concept, the costs associated with the current technologies are quite high. There are many different reasons for the high cost, but they are mostly due to poor economies-of-scale. Hasan is working from the other direction. By starting out with multifunctional and intensified equipment at smaller scales, Hasan will be designing completely novel technology for a completely novel process.
“Our methodology based on rigorous design and optimization theory and screening algorithms shows a lot of promise for discovering innovative processes without really waiting for a eureka moment,” said Hasan.
One such technology discovered in Hasan’s lab for integrated carbon capture and conversion has recently resulted in a patent application. Hasan has also had success in leading the frontier of process intensification research. He is currently the principal investigator of a National Science Foundation grant, and is one of the co-principal investigators in the RAPID Institute Project, a $4.2 million project led by the Texas A&M Energy Institute. Last year, Hasan was invited to participate in the National Academy of Engineering EU-US Frontiers of Engineering Symposium. He was also awarded the Ralph E. Powe Junior Faculty Enhancement Award from Department of Energy-Oak Ridge Associated Universities in 2015.
