An olefins process is described which combines cracking of a hydrocarbon feedstock with the coupling of methane using an oxygen-affording gas such that the heat evolved in the exothermic methane coupling reaction is effectively transferred to the endothermic cracking process in a manner which does not allow the non-hydrocarbon products in the effluent of the methane coupling reaction to mix with the effluent of the cracking process. By combining the cryogenic requirements of the two processes, the refrigeration used in air liquifaction to separate oxygen...
A process to make olefins which combines cracking of a hydrocarbon feedstock with the coupling of methane, said process comprising: the coupling in a first zone of a first feed which is essentially methane using an oxygen-affording gas to produce a product containing C2 hydrocarbons; hydrocarbon cracking in a second zone of a second feed which contains predominantly saturated hydrocarbons to form primarily an olefin-containing product; effectively transferring heat evolved by said coupling from said first zone to said second zone to provide a majority of...
