Abstract: In the production of ethylene by thermal cracking of hydrocarbons at above 750 DEG C., followed by indirect cooling in quench boilers, the gases are passed through the cooling tubes at a speed above 50 kg./m.2/sec., e.g. 60-70 kg./m.2/sec. The temperature of the cooling tubes is preferably above 310 DEG C. maintained by a steam pressure of at least 100 atmospheres. The velocity of the gas in the inlet cone of the boiler should be above 20 kg./cu.m./sec.
