Title:
自己熱分解反応装置流出物からエチレンを回収する方法
Document Type and Number:
Japanese Patent JP2009502915
Kind Code:
A
Abstract:
The process of this invention represents an improved method for recovering a purified ethylene product and optionally a purified hydrogen product from the effluent of an autothermal cracking reactor. The process consists of cracked gas chilling, rough separation of a hydrogen-rich stream, demethanization, separation of ethylene from the demethanizer bottoms product, and final purification of the ethylene product. Hydrocarbons heavier than ethylene, including ethane, propylene, and propane are recycled to the ATC reactor. Optionally a purified hydrogen product can be obtained from the hydrogen-rich stream. The invention is particularly useful when the fresh hydrocarbons feed to the autothermal cracking reactor is ethane or a mixture of ethane and propane.
