Carbon capture pilot plant

Bioenergy with carbon capture and storage (BECCS), is considered to be one of the most important technologies for achieving a reduction of atmospheric carbon dioxide. Unfortunately, today's commercial capture systems are both energy-intensive and costly, which has so far hindered many large-scale investments. RISE collaborates with both academia and industry to develop new energy effective and cost effective technology based on eutectic solvents and ionic liquids. As part of this work, RISE has installed a functioning CO₂ capture pilot plant inside of a transportable 20-foot container.  The pilot enables continuous testing over continuous periods of time. Trials at a specific site only require an electrical connection and a connection to the flue gases which are to be evaluated. With the pilot plant, RISE offers a unique opportunity for industries to evaluate CO₂ capture from their unique gas streams. A pilot carbon capture study can provide valuable information about the carbon capture performance and give valuable input to large-scale investment calculations.

Carbon capture in the pilot is done with absorption and stripper columns.  While this process is well known, today's technology is energy intensive and expensive.  One purpose of the pilot plant is to evaluate different absorption media in order to find more energy efficient solutions.  Traditional amines can be replaced with newly developed eutectic mixtures that can offer better absorption and stripping in the stripper column with less temperature difference required (which saves energy).  RISE researchers are familiar with the development of new eutectic mixtures.  RISE can gain access to the latest and most promising eutectic mixtures for testing.

RISE can offer evaluation of the absorption/stripper capture method on real flue gases.  Each industrial plant has its own composition of flue gases that should to be evaluated on a smaller scale before making a full-scale investment.  To get an indication of how much of the flue gas can be captured and what purity can be achieved, a real pilot trial is required.  With newly developed absorption media available, the efficiency and cost of a full-scale plant can be significantly impacted.  RISE's facility can be crucial tool for providing the data required prior to major investments in carbon capture.
