Case Studies

Students in the CHBE 488 588 course work with real world SMEs on the forefront of CCCS technologies. Together with the SMEs, the instructional team creates case studies to evaluate certain environmental aspects of their technologies under a set of conditions from course instructor guidance.

Students also work to gain insights into competitors of their assigned SME and produce a technology lecture for the class

Clean O2

Carbon dioxide emissions from the flue gas emissions of natural gas industrial or commercial boilers are captured and converted to commercial grade pearl ash (carbonates).

Carbon Cure

Carbon dioxide is contacted with concrete (cement + aggregate + H2O) where it is first converted to carbonate (CO3)2- and then to calcium carbonate, sequestering the carbon dioxide in the final concrete.

Mangrove Water Technologies

Carbon dioxide and saline wastewater from the oil and gas industry are captured, treated, and converted to desalinated water, carbonate salts, and acids such as HCl.


Solid Carbon

Direct air contact technology is used to capture CO2 directly from the atmosphere. CO2 is then concentrated and transferred to geological basalt formations, most of which are on the subseafloor, where it reacts with the basalt rock to form carbonate rock.

Carbon dioxide is captured from the atmosphere using direct air capture. Using renewable power or waste heat, highly concentrated carbon dioxide is collected, which can subsequently be permanently stored for negative emissions or used as a feedstock for the production of carbon-based materials.



Carbon dioxide from flue gas emissions are captured and converted, using proprietary electrochemical stack cell systems, into carbon-based materials such as methanol, syngas, or others.




Using proprietary pulsing froth gas-liquid mass-transfer technology, a more efficient solvent absorption and separation carbon capture system leading to smaller equipment/volume is obtained, for both pre-combustion and post-combustion cases.
