Problems solved by technology

Unfortunately, their industrial use is limited by the difficulty of scaling the system to a large enough size for large-scale operation
In particular, there are great difficulties in introducing the feed to be oxidized into the reactor without clogging the feed ports, and in removing the salts generated during operation without clogging the outlet

Embodiment Construction

[0208] The molten salt treatment system according to the invention can be used, especially as a molten salt oxidation (MSO) reactor. MSO technology is a thermal process capable of destroying the organic components of mixed waste, hazardous waste, and energetic materials while retaining the inorganic components of the salt.

[0209] Molten salt oxidation is a flameless thermal process that can be described as the addition of a liquid or solid feed and excess air or oxygen-containing gas to a salt or salt mixture such as sodium carbonate (Na 2 CO 3 ) and sodium chloride (NaCl)) in a molten salt bath in which organic materials are oxidized to mainly carbon dioxide and water in the molten salt. Typically, the waste stream is introduced below the liquid level of the molten salt, but it can be introduced above the surface. The choice of salt for an MSO system is highly dependent on the type of feed to be treated; if sour gas treatment is desired, it would be desirable to include a...

Abstract

A molten salt treatment system and process can include one or more tubular conduits flowably connected to a molten salt reactor, the tubular conduit containing concentrically within it a pipe or a shaft separated by an annular space therebetween, and one or more gas sources connected to feed gas into the annular space. The system may include a scrubbing device flowably connected to a molten salt reactor off-gas outlet to receive an off-gas, a first heating device configured to heat the effluent from the scrubbing device, and a filtering device flowably connected to receive the effluent from the heating device. An overflow conduit may be flowably connected to a molten salt reactor overflow outlet to receive molten salt therefrom and discharge the molten salt to a salt recovery vessel, and a blower or other gas mover may be connected to the molten salt reactor and the recovery vessel to prevent backflow of cold gases through the overflow outlet to the molten salt reactor.

Description

technical field [0001] The present invention relates to molten salt treatment systems and processes. More specifically, the present invention relates to molten salt reactor feed delivery, off-gas treatment, and spent salt removal systems and processes. Background technique [0002] Molten salt processing systems can be used to oxidize organic compounds, such as chlorinated organic materials, to form carbon dioxide, water, and salt. Unfortunately, their industrial use is limited by the difficulty of scaling the system to a large enough size for large-scale operation. In particular, there are great difficulties in introducing the feed to be oxidized into the reactor without clogging the feed ports, and in removing the salts generated during operation without clogging the outlet. Accordingly, methods and apparatus that address the problems of large-scale molten salt reactor use for oxidation and other purposes would be advantageous. Contents of the invention [0003] In on...
