Open the CIPO recordAbstract From the Canadian patent
In a process for the thermal cracking of hydrocarbons the hydrocarbons are heated to reaction temperature and conducted into the reaction zone, where the flow is upward from below. The fluid/gas mixture is set in tangential rotation in the pressure vessel by means of a helix system or by nozzles. A uniform delay time is obtained without the need for intermediate plates which impede cleaning operations.
