Abstract
A method of steam cracking includes using a steam cracking arrangement that has a fired cracking furnace, a quench cooling train, and rotating equipment at least partly driven by electric energy. A process gas stream is passed through the furnace and the cooling train. A steam generation arrangement, operated in thermal association with the cracking arrangement, results in superheated high pressure steam at a first pressure level of 30 and 175 bar absolute pressure and at a first temperature level. No steam at a higher temperature level than the first is generated. The superheated high pressure steam is partially adiabatically and isenthalpically expanded to a second lower pressure level. The first temperature level is selected such that each intermediate temperature level reached at intermediate pressure levels of more than 20 bar during the adiabatic and isenthalpic expansion process is between 5 and 120 K above the dew point of steam.
