Abstract
In some examples, a vapor phase product and a liquid phase product can be separated from a heated mixture that includes steam and a hydrocarbon. The vapor phase product can be steam cracked to produce a steam cracker effluent. The steam cracker effluent can be contacted with a quench fluid to produce a cooled steam cracker effluent. The steam cracker effluent can be at a temperature of >300° C. when initially contacted with the quench fluid. A tar product and a process gas that can include ethylene and propylene can be separated from the cooled steam cracker effluent. The tar product can be hydroprocessed to produce a first hydroprocessed product. A hydroprocessor heavy product and a utility fluid product can be separated from the first hydroprocessed product. The quench fluid can be or include at least a portion of the utility fluid product.
