<p>A hydrocarbon steam cracking method wherein erosive particles are injected upstream from a quenching exchanger (4). Particles recovered in a primary separator (5) are cooled by pneumatic conveyence (7, 8, 9) through a transfer line (12), separated from the carrier gas, depressurised and then screened in a vibrating screen (19) at atmospheric pressure in a nitrogen atmosphere before being recycled.</p> |
