Chemical Sorbents for Fixed Bed Mercury (Hg 0) Control

STATUS: Awarded
ACTIVE SOLVERS: 177
POSTED: Oct 26 2015
SOURCE: InnoCentive

The Seeker desires a chemical adsorbent or method which can be used to remove elemental mercury from flue gas in a coal fired power plant.  The chemical adsorbent or method should be suitable for use in a fixed bed configuration.  A number of methods, such as the use of activated carbon are known, however not applicable to conditions of high humidity and in the presence of condensation. 

This Challenge requires only a written proposal.

Challenge Overview

The Seeker desires a chemical adsorbent or method which can be used to remove elemental mercury from flue gas in a coal fired power plant.  The chemical adsorbent or method should be suitable for in-line use in a fixed bed configuration, downstream from the wet flue gas desulfurization (FGD) unit, under continuous operation for at least three years.  The chemistry should be effective for flue gas operating at a nominal temperature of 150oF in the presence of water vapor, condensation, and SO2 (which renders the condensate acidic).  The use of activated carbon is well known, however not applicable to conditions of high humidity and in the presence of condensation. 

The chemical adsorbent or method will ideally utilize relatively inexpensive, commercially available reagents, and would not, on its own merits, create a safety or potential environmental hazard.   

This is a Theoretical Challenge that requires only a written proposal to be submitted.  The Challenge award will be contingent upon theoretical evaluation of the proposal by the Seeker. 

To receive an award, the Solvers will have to transfer to the Seeker their exclusive Intellectual Property (IP) rights to the solution.  

Submissions to this Challenge must be received by 11:59 PM (US Eastern Time) on November 30, 2015.  Late submissions will not be considered.

What is InnoCentive?

InnoCentive is the global innovation marketplace where creative minds solve some of the world's most important problems for cash awards up to $1 million. Commercial, governmental and humanitarian organizations engage with InnoCentive to solve problems that can impact humankind in areas ranging from the environment to medical advancements.

What is a Theoretical IP Transfer Challenge?

An InnoCentive Theoretical Challenge builds upon an idea but is not yet a proof of concept. A solution to a Theoretical Challenge will solidify the Solver's concept with detailed descriptions, specifications and requirements necessary to bringing a good idea closer to becoming an actual product or service.

This Challenge is a Theoretical-IP Transfer Challenge, meaning that Solvers must relinquish all rights to the Intellectual Property (IP) for which they are awarded. By contrast, Theoretical-Licensing means that the Seeker is requesting non-exclusive rights to use the winning solution. For these forms of a Theoretical Challenge, Solvers that do not win retain the rights to their solution after the evaluation period is complete. The Seeker retains no rights to any IP not awarded.
