Systems and processes for transferring heat using molten salt during hydrocarbon upgrading

A process for thermally treating a hydrocarbon-containing stream comprising:

• introducing the hydrocarbon-containing stream into channels of a heat transfer medium, wherein the heat transfer medium is positioned within an interior chamber of a pressure containment vessel;
• supplying electrical current to the heat transfer medium;
• converting the electrical current to heat, thereby heating the hydrocarbon-containing stream within the channels of the heat transfer medium;
• converting the hydrocarbon-containing stream to an effluent within the channels of the heat transfer medium;
• removing the effluent from the channels of the heat transfer medium;
• introducing the effluent into a heat exchanger, wherein the heat exchanger houses molten salt, and the molten salt is at a first temperature;
• transferring heat from the effluent to the molten salt and increasing a temperature of the molten salt to a second temperature,
• transferring heat from the molten salt to a heat sink reservoir comprising a supply of molten salt.
