Abstract:
A method and system are disclosed for treating the effluent from a hydrocarbon pyrolysis unit employing a small primary fractionator. The method comprises cooling the effluent from a furnace through a first heat exchanger, a vapor-liquid separator, and a second heat exchanger before it is passed to a fractionator for further processing. These heat exchangers may also be utilized to heat a utility fluid as part of the cooling process. Further, one or more generators and a third heat exchanger may also be used to assist in heat recovery for the process.
