Abstract:
1. Analysis equipment for determining a chemistry of an organic component and a caustic component of a reusable organic caustic solution, the analysis equipment comprising: an autoclave containing a metallic component and the reusable organic caustic solution at elevated temperature and pressure, the reusable organic caustic solution having been utilized for at least one cycle of removing a ceramic coating from the metallic component; a storage tank for storing, the reusable organic caustic solution after removal from the autoclave; a filter for removing particles of the ceramic coating dispersed in the reusable organic caustic solution from the reusable organic caustic solution; a pump for circulating the reusable organic caustic solution from the tank through the filter; a pipe connecting the storage tank to the pump, the pump to the filter and the filter to the storage tank; and at least two sensors positioned between the filter and the storage tank to measure at least two physical properties of the reusable organic caustic solution after removal of the particles from the reusable organic caustic solution, the at least two physical properties selected from the group consisting of electrical conductivity, opacity, refractive index, density, fluidity and the speed of sound in the solution.
