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.
