Challenge: Reducing the diffusion of hydrogen chloride gas through the refractory barrier


The Seeker operates equipment that has a physical barrier of refractory material between the reaction chamber and the combustion chamber. The reaction produces high-temperature hydrogen chloride (HCl) gas with limited diffusion through the shield into the combustion chamber.

Searchers are looking for a solution to reduce this diffusion even further. The solutions must withstand the active operating environment of the reactor while maintaining or improving heat transfer between the chambers.

This theoretical challenge requires only a written proposal.

overview

Many processes that produce chemical products rely on heating the reaction chamber by the combustion chamber being physically separated from the reaction chamber by a thermally conductive barrier. If the chemical process produces a gaseous product or by-product, the shield must be impermeable to prevent contamination of the combustion chamber and its exhaust. The Seeker conducts a process that produces high-temperature hydrogen chloride (HCl) gas in a reaction chamber. The HCl gas diffuses limitedly through the refractory material of the shield.

Submissions for this Challenge must be received by 11:59 PM (US Eastern Time) on July 18, 2022.
