3 Introduction Electric-based heating technologies Strengths & weaknesses of the technologies R&D challenges Outlook

4 Ethylene is typically produced by steam cracking of Naphtha: Pyrolysis (oil or gas fired furnace C) Quenching Liquid separation Compression and gas separation Electrical cracking is an important option to make ethylene production more sustainable, but... What is the state of the art and the respective strengths and weaknesses? What are the user requirements? What are the important research questions?

5 Electric-based process heating systems use electric currents or electromagnetic fields to heat materials directly or indirectly. Resistance heating Induction heating Arc/Plasma heating Microwave/RF heating Ultrasonic heating Infrared heating Electron beam heating Laser heating Ultraviolet heating

6 This refers to systems that generate heat by passing an electric current (AC or DC) through a conductor, causing an increase in temperature (direct or indirect) Resistance Induction

7 Glass industry Metal industry Process flow heaters Food industry Sintering ceramics Drying

8 Heating by use of an electric arc/plasma Plasma

9 Heating and melting of metals Melting high- alloy steels Titanium industry Diamond film production Hydrocarbon cracking V Anode Cathode Arc Tangential Plasma gas injection Hydrocarbon Feedstock Quench water injection

10 Microwave and RF heating systems use electromagnetic radiation to excite water molecules in the material, or to generate heat in a susceptor (for example, graphite). 1-Microwave generator(magnetron) 2-Wave guide 3-Heated object 4-Vibrating molecules 5-Heat

17 Plastics provide large benefits to our community and the best way to produce their building blocks is through steam cracking

18 It is desirable to transform steam cracking technology for a more sustainable business and it is up to the industry to come with a plan

19 To reduce to footprint of steam cracking using renewable electricity for heating is the only option

20 Should the government invest more in demonstration projects or in innovation?
