<p>Combustion air, prior to being introduced into the cracking furnace (5) in a hydrocarbon pyrolytic conversion and separation system, is preheated by employing bottom pumparound (24), top pumparound (28) and/or quench water (31) streams diverted from the primary fractionator (14) externally connected to the pyrolysis reactor (5) in order to optimize the thermal efficiency of the overall process.</p> |
