Carbon capture (CCS) has become an important economic, industrial and environmental issue. However, there are technical aspects you may not understand because they typically aren’t covered in undergraduate curriculums. Attend this sponsored webinar if you not only design and operate a CCS plant, but also are expected to optimize or troubleshoot operations. You’ll take a focused look at the engineering chemistry—not just the process engineering or the chemistry—that occurs starting from the carbon absorption unit to the final carbon sequestration step. By understanding in detail the chemistry in each unit, you’ll be prepared to make educated decisions on how to make changes to the process engineering units.
Attend and you’ll examine the solubility behavior of CO2 and other acid gases in water as temperature, pressure and solution composition changes. You’ll investigate the multi-stage absorption of CO2 in alkaline solutions, including the liquid-vapor composition distribution in the absorption column. You’ll explore the multi-stage stripping of CO2 from alkaline solutions, including the liquid-vapor composition distribution and the phase stability of CO2 during transport and the potential for a corrosive water phase to separate from the CO2. You’ll also consider the reactions between CO2 and reservoir brines and rock during the sequestration step.
You’ll leave with a better understanding of why an absorber or stripper is not performing to maximum efficiency as well as how to identify the integrity operating window for CO2 transport. In addition, you’ll have the confidence to qualitatively estimate the capacity of a reservoir for CO2 storage and anticipate side reactions that can cause process disruptions.
You’ll gain a better understanding of:
- The acid-base reactions between CO2 and absorbing chemicals
- The impact of T/P conditions and composition on the extent of CO2 absorption and stripping
- The different CO2 phases and what exits as temperature, pressure and compositions change
- The effects of oxidation by absorbed O2 on the formation of H2SO4 and HNO3 in dense phase CO2
- The breakdown of the different reactions between CO2 and reservoir materials including alkaline rocks, silicates and reservoir fluids.
- Key chemistry and process factors that impact the efficiency of the CCUS process
