The Battelle Fused Salt Scrubbing Process has been subjected to exhaustive engineering analysis and optimized for operation in continuous mode. Engineering analyses are nearly complete and design drafting is well underway. Detailed engineering analysis has proved somewhat more time consuming than originally envisioned. The process has been operated in batch process mode with continuous recirculation of the extracting salt from the de-entrainer to the venturi scrubber. In this configuration, operation began with contact of the gas with clean salt and terminated when the extraction capacity of the salt was exhausted. The salt was subsequently regenerated, again in batch mode, or was replaced with fresh salt. Highly efficient extraction of sulfur compounds and particle scrubbing was demonstrated and it was shown that a vertically oriented venturi scrubber was an efficient device with which to circulate the molten salt scrubbing liquid. No mechanical pump was required. It remains to be demonstrated that the salt can be continuously regenerated simultaneously with extraction of sulfur compounds and particles. To achieve continuous operation with simultaneous extraction of sulfur compounds, particle removal, and regeneration of the extraction capacity of the salt a substantially revised process has been conceived.
