Abstract
Embodiments of the present disclosure include methods for producing aromatic products, the methods including separating a crude oil and condensate feed into at least a light naphtha stream, a heavy naphtha stream, and a bottoms stream, reforming at least a portion of the heavy naphtha stream to produce a reformate stream, feeding a cracker feed stream, comprising the light naphtha stream, the bottoms stream, and a reformate extraction raffinate, to an olefins cracker to produce cracker products comprising pyrolysis gasoline, and introducing an extractor feed stream comprising the pyrolysis gasoline and the reformate to an aromatic extraction unit to produce an aromatic product and the reformate extraction raffinate.
Claims6
A method of producing aromatic products, the method comprising:
- separating a crude oil and condensate feed into at least a light naphtha stream, a heavy naphtha stream, and a bottoms stream;
- feeding a cracker feed stream, comprising the light naphtha stream and the bottoms stream, to an olefins cracker to produce cracker products;
- extracting the aromatics products from at least a portion of the cracker products to produce a first aromatic product stream and an aromatics extraction raffinate stream;
- reforming at least a portion of the aromatics extraction raffinate stream and the heavy naphtha stream to produce a reformate stream;
- and
- extracting additional aromatic products from the reformate stream to produce a second aromatic product stream and a second aromatic extraction raffinate stream;
- wherein the cracker feed stream further comprises the second aromatic extraction raffinate stream.
