Abstract
Embodiments of the present disclosure describe methods and systems of producing light olefins and aromatics from a gas condensate feedstock using minimal pretreatment of the gas condensate feedstock. The gas condensate feedstock is separated into several streams including a heavy cut stream to produce aromatics and a light cut stream to produce lighter olefins. Other streams can be produces to maximize production of aromatics and lighter olefins depending on the method used.
Claims15
A method for production of light olefins and aromatics from a gas condensate feedstock, the method comprising:
- supplying a hydrogen stream and a gas condensate feedstock containing ethane, propane, butane, light naphtha, and nitrogen and sulfur containing impurities to a hydrotreating unit for substantial removal of the nitrogen and sulfur containing impurities from the gas condensate feedstock to produce a purified feedstock;
- supplying the purified feedstock to a splitter and separating a light cut stream and a heavy cut stream from the purified feedstock, the light cut stream containing a first plurality of hydrocarbons with a boiling point less than about 300° C. and the heavy cut stream containing a second plurality of hydrocarbons with a boiling point greater than 300° C.;
- supplying the light cut stream to a catalytic cracking unit to produce a cracked product stream containing a portion of the ethane, the propane, and the aromatics;
- supplying a first portion of the cracked product stream to a steam cracker to produce a first olefin product stream containing ethylene, propylene, and the aromatics, and supplying a second portion of the cracked product stream to a gas concentration unit for further processing to produce a second olefin product stream containing the propylene and the aromatics;
- supplying the heavy cut stream from the splitter to a catalytic reformer unit to produce an aromatics-enriched stream and a light hydrocarbon stream;
- combining the light hydrocarbon stream with the light cut stream from the splitter before processing in the catalytic cracking unit;
- and
- supplying the aromatics-enriched stream to an aromatic recovery complex for production of benzene, toluene, and xylene.

- a hydrotreating unit configured for receiving a hydrogen stream and a gas condensate feedstock containing ethane, propane, butane, light naphtha, and nitrogen and sulfur containing impurities, removing the nitrogen- and sulfur-containing impurities from the gas condensate feedstock, and producing a purified feedstock;
- a splitter in fluid communication with the hydrotreating unit and configured for receiving the purified feedstock and separating the purified feedstock into a light cut stream and a heavy cut stream, the light cut stream containing a first plurality of hydrocarbons with a boiling point less than about 300° C. and the heavy cut stream containing a second plurality of hydrocarbons with a boiling point greater than 300° C.;
- a catalytic cracking unit in fluid communication with the splitter and configured for receiving the light cut stream and producing a cracked product stream containing a portion of the ethane, the propane, and the aromatics;
- a steam cracker in fluid communication with the catalytic cracking unit and configured for receiving a first portion of the cracked product stream and producing a first olefin product stream containing ethylene, propylene, and the aromatics;
- a gas concentration unit in fluid communication with the catalytic cracking unit and configured for receiving a second portion of the cracked product stream and producing a second olefin product stream containing the propylene and the aromatics;
- a catalytic reformer unit in fluid communication with the splitter and configured for receiving the heavy cut stream and producing an aromatics-enriched stream and a light hydrocarbon stream, the light hydrocarbon stream to combine with the light cut stream from the splitter prior to the catalytic cracking unit;
- and
- an aromatic recovery complex in fluid communication with the catalytic reformer unit and configured for receiving the aromatics-enriched stream and producing benzene, toluene, and xylene.
