Abstract
The present invention provides a method and an apparatus for pyrolytically cracking a hydrocarbon vapor feedstock. The hydrocarbon vapor feedstock is contacted with water prior to cracking. While the hydrocarbon vapor feedstock is being contacted with water, both the feedstock and the water are heated by indirect heat exchange with at least one process stream containing waste heat. Consequently, a portion of the water vaporizes and combines with the hydrocarbon vapor feedstock. The hydrocarbon vapor feedstock is subsequently cracked in the presence of the vaporized water.
