Abstract (en)
[origin: US5177292A] PCT No. PCT/FR90/00273 Sec. 371 Date Dec. 12, 1990 Sec. 102(e) Date Dec. 12, 1990 PCT Filed Apr. 13, 1990 PCT Pub. No. WO90/12852 PCT Pub. Date Nov. 1, 1990.A method of steam cracking hydrocarbons in a steam cracking furnace (10) having tubes (12) connected to indirect quench menas (16) for the gaseous effluent leaving the furnace, the method consisting in allowing a layer of hard coke to form on the inside walls of the furnace tubes (12) and then in injecting a small quantity of solid erosive particles into the steam and hydrocarbon feedstock to be cracked, with the particles being separated from the gaseous effluent in a cyclone (28) provided at the outlet from the indirect quench means. The invention serves in particular to enable a steam cracking installation to operate continuously.
