Abstract
A method for processing a condensate feedstock may include passing the condensate feedstock to a first separation unit, and separating the condensate feedstock into at least a light fraction stream and a heavy fraction stream. Another method for processing a condensate feedstock may include passing the condensate feedstock to a first separation unit, and separating the condensate feedstock into at least a light fraction stream, an intermediate fraction stream, and a heavy fraction stream. Various downstream processing steps are further disclosed in the present disclosure.
Claims20
A method for processing a condensate feedstock, the method comprising:
- passing the condensate feedstock to a first separation unit, and separating the condensate feedstock into at least a light fraction stream and a heavy fraction stream, wherein:
- the light fraction stream has a maximum boiling point that is about equal to a minimum boiling point of the heavy fraction stream;
- the light fraction stream has a maximum boiling point of from 170° C. to 260° C. and the heavy fraction stream has a minimum boiling point of from 170° C. to 260° C.;
- and
- at least 90 wt. % of the condensate feedstock is contained in the combination of the light fraction stream and the heavy fraction stream;
- cracking the heavy fraction stream in an FCC reactor to form an FCC effluent;
- passing the FCC effluent to a second separation unit to form a cat-cracked naphtha stream;
- and
- passing the cat-cracked naphtha stream and the light fraction stream to a gasoline preparation unit or to a mixed feed steam cracker unit.
