Abstract: Methods for separating hydrocarbons may include dehydrogenating a feed stream to form a product stream including one or more olefins. The methods may include compressing the product stream and separating the compressed product stream into at least a second product stream and a first non-condensable gas stream. The first non-condensable gas stream includes one or more of hydrogen, nitrogen, methane, carbon monoxide, and carbon dioxide, and the second product stream includes hydrocarbons. The method may include reducing the pressure of the first non-condensable gas stream to form a second non-condensable gas stream and heating the second non-condensable gas stream to form a third non-condensable gas stream. The method may include passing at least a portion of the third non-condensable gas stream to one or more of: a combustor, a pressure swing adsorption system, a dehydrogenation reactor, a compressor, a reactor feed pretreatment bed, or a dryer.
