The process is operated in such a way that, during cracking, the temperature is 400 to 450 DEG C and preferably some 420 DEG C, the pressure is 17 to 27 bar and preferably some 22 bar and the cracking process takes between 6 minutes and 10 hours, preferably about 1 hour. Before subsequent refining, the hydrocarbon compound obtained by cracking may be cooled to around room temperature, preferably to some 40 DEG C, maintained at a pressure of at least one bar and preferably about 6 bar and preferably stored for about 1 hour. The device comprises a tank (7) for the intermediate storage of the hydrocarbon compound before its subsequent refining and a controllable valve (8) on an exhaust line (17) of the tank (7) to determine the pressure in the tank (7), which is preferably lagged and high-pressure resistant. |
