Abstract:
The present invention relates to a method of preparing butadiene and a device for preparing the same. According to the present invention, since butane is used as a diluent gas, even when a refrigerant belonging to a grade lower than a very low temperature refrigerant is used, a C4 mixture and gas products excluding butadiene may be easily separated, and loss of active ingredients may be minimized, which may increase productivity while reducing raw material costs, thereby improving economic efficiency. In addition to these advantages, when the method and device of the present invention are used, high-purity butadiene may be safely prepared.

Claim (Index 10):
The method according to  claim 1 , further comprising:\n feeding COx and O 2 , which are additionally separated in the degasification part, into the condensation system; removing high-boiling point materials by passing crude hydrocarbons comprising n-butane, butene, and butadiene excluding COx and O 2 , which are additionally separated in the degasification part, through a high-boiling point material removal part; feeding crude hydrocarbons, from which the high-boiling point materials are removed, into the purification part.
