Abstract
A method of thermally cracking a hydrocarbon feed (105) includes feeding the hydrocarbon feed (105) into at least one coil (130) in a reaction section (112) of an electric heater (110), using electrical energy to heat the hydrocarbon feed (105) in the electric heater (110) to a reaction temperature, and directing a reaction output from the electric heater (110) to at least one exchanger (150) to cool the reaction output.
Claims15
A reactor for cracking a hydrocarbon feed, comprising:
- a heater chamber defining a reaction section of the heater;
- a plurality of electrical heating elements disposed within the heater chamber, wherein the electrical heating elements are electrically powered;
- at least one coil extending from a feed inlet through the reaction section;
- and
- a primary exchanger comprising an inlet fluidly connected to the at least one coil and an effluent outlet.
