Abstract: A high temperature electrolysis cell refractory system comprises at least one precast and predried monolithic refractory flooring module, precast and predried monolithic refractory wall modules, and at least one precast and predried monolithic refractory ceiling module, wherein the flooring module(s), wall modules and ceiling module(s) are configured for assembly to form a sealable electrolysis cell in which adjacent modules have interlocking surfaces. The refractory system is assembled within a steel containment shell to provide a high temperature electrolysis cell.

Abstract: A monolithic refractory ceramic tube sheet for use in all-ceramic air-to-air indirect heat exchangers, the heat exchanger used in medium to high temperature, and high pressure applications. A method for forming the monolithic tube sheet includes-casting a refractory ceramic in a mold, where portions of the mold comprise the housing of the heat exchanger. Precisely formed negatives are used to form through channels and vacancies within the tube sheet, which are precisely positioned within the mold allowing uniform and flush formation of openings that receive the ceramic tubes therein. The same mold is used to provide both tube sheets of a tube sheet pair allowing accurate alignment of tubes within the exchanger vessel resulting in ease of assembly and equal loading of tubes when in use.
