Abstract: The present disclosure describes a method of separating a carbon allotrope from a salt and a separation system for the same. The method may include adding a solid comprising the carbon allotrope and the salt to a solution comprising the salt, performing a first filtration on the solution at a first temperature to remove the carbon allotrope from the solution, adjusting the temperature of the solution to a second temperature to precipitate a first portion of the salt, performing a second filtration on the solution at the second temperature to remove the first portion of the salt from the solution, adjusting the temperature of the solution to the first temperature to dissolve a second portion of the salt in the solution, and recycling the solution.

Abstract: The present disclosure describes a contactor device which may include a housing including a tank and a lid, wherein there is a seal between the tank and the lid, at least one liquid inlet, at least one gas inlet, a bed of a contact medium contained within the tank and positioned over a barrier having a plurality of through holes, at least one liquid outlet, at least one gas outlet, and a guide plate positioned to prevent the liquid from reaching the gas outlet. Methods of operating a contactor device are also described and may include methods of capturing and converting carbon dioxide to commercially useful materials.
