摘要： The invention relates to a process for the steam cracking of a feedstock composed of at least 80% by weight, in particular of at least 90% by weight, of ethane, the process comprising a steam cracking of the feedstock in a furnace (2), then a quenching of the pyrolysis products, then a compression operation, then a series of successive operations on the products resulting from the quenching, the said series of operations comprising a washing operation, followed by a drying operation and at least one compression operation, and finally a fractionation by cryogenic distillation. A selective hydrogenation operation, followed by a catalytic conversion operation, will be inserted into the said process, after the drying operation and before the fractionation, in order to partially convert the ethylene predominantly into propylene.
