Abstract
Systems and processes for cracking hydrocarbons to produce olefins herein includes heating a hydrocarbon feedstock or a mixture comprising steam and hydrocarbons to a first temperature to form a preheated feed, and also include electrically heating steam to a second, higher, temperature to form a superheated reaction steam. The preheated feed is then mixed with the superheated reaction steam to form a reaction mixture at a cracking temperature, thereby cracking the hydrocarbons to form olefins, producing a reaction effluent. The reaction effluent is then quenched and separated effluent to recover the olefins.

A process of cracking hydrocarbons to produce olefins, the process comprising:
- heating a hydrocarbon feedstock or a mixture comprising steam and hydrocarbons to a first temperature to form a preheated feed;
- electrically heating steam to a second, higher, temperature to form a superheated reaction steam;
- mixing the preheated feed with the superheated reaction steam to form a reaction mixture at a cracking temperature, and cracking the hydrocarbons to form olefins, producing a reaction effluent;
- quenching the reaction effluent;
- and
- separating the reaction effluent to recover the olefins.
A system for cracking hydrocarbons to produce olefins, comprising:
- a heating system configured for heating a mixture comprising steam and hydrocarbons to a first temperature to form a preheated mixture;
- an electrical heating system configured for electrically heating steam to a second, higher, temperature to form a superheated reaction steam;
- a mixing system configured for mixing the preheated mixture with the superheated reaction steam to form a reaction mixture at a cracking temperature;
- an adiabatic reaction zone for adiabatically cracking the hydrocarbons to form olefins, producing a reaction effluent having a fourth temperature;
- a quench system for quenching the reaction effluent;
- and
- a separation system for separating the reaction effluent to recover the olefins.
