| titleOfInvention | PROCESS FOR FLEXIBLE VAPOCRAQUING AND CORRESPONDING VAPOCRACKING INSTALLATION |
| abstract | The flexible steam cracking process of hydrocarbon feeds comprises the injection at at least one point upstream of an indirect quenching exchanger (4), the cracking zone (2) remaining in communication with the downstream means (6) for treating the hydrocarbons. cooled effluents, of particles of average size between 0.02 mm and 4 mm, at a circulation speed in the indirect quenching means (4) of 20 to 180 m / s, and in sufficient quantity to limit the increase in temperature output means (4) to a value less than 100 deg.C per month. At least 70% by weight of the quantity of particles injected is introduced between the outlet of the cracking zone (2) and the tubes of the indirect quenching exchanger (4). At intervals of less than 4 months, chemical decoking of the tube cracking zone is carried out, by establishing conditions for accelerated coke gasification, for example by injecting gasification catalyst compounds with water vapor, or by air and / or steam decoking. |
