A Low-Energy, Low-Cost Process for Stripping Carbon Dioxide from Absorbents
Glycol Heater, Stripper, MEA Delivery Tank, CO2 and H2O Collection Apparatus
AIL Research, Inc. (AIL) is in the second phase of a small business
initiative research (SBIR) project that is assessing the economic and
technical feasibility of a carbon dioxide (CO2) stripper
that uses an internally heated contactor. The project will determine
whether the construction of the internally heated contactor is
compatible with the operating conditions of a monoethanolamine stripper
and an advanced scrubber (e.g., one that uses a mixture of potassium
carbonate and piperazine) and it will also determine the maintenance
procedures required to fall within acceptable operation and maintenance
practices at power plants.
AIL will also work to scale-up the CO2 stripper concept
that utilizes an internally heated contactor. This work includes the
development of both the surface treatment and physical structure for
the contact surface of the internally heated stripper. Researchers
will also identify a solvent that will produce the most
economically-viable CO2 scrubber system by testing several thermally-regenerated CO2
absorbents under controlled laboratory conditions, while gaining a
better understanding of the operating parameters that control scrubber
performance. In addition, this project will evaluate the impact that
the proposed CO2 capture system will have on the performance and economics of coal-fired power plants.
