Abstract
A method and system are disclosed for co-production of olefins and electric power. The method includes determining a separation level, separating a hydrocarbon feed into a light fraction stream and a heavy fraction stream based on the determined separation level; generating electric power from the heavy fraction stream; and cracking the light fraction stream in a pyrolysis unit to produce an effluent comprising olefins. The separation level may be based on olefin production requirements and electric power requirements or specific split of the hydrocarbon feed to be utilized for power generation and olefin production.
Claims25
A hydrocarbon processing system comprising:
- a separation unit configured to:
- divide a hydrocarbon feed into a light
- fraction stream and a heavy fraction stream;
- a process control unit having one or more control units and configured to adjust the separation level in the separation unit based on olefin production requirements and electric power requirements;
- a pyrolysis unit in fluid communication with the separation unit, wherein the pyrolysis unit is configured to create an effluent from a portion of the light fraction stream;
- and
- a fuel conversion unit in fluid communication with the separation unit and configured to convert a portion of the heavy fraction stream into a turbine feed;
- and
- a turbine in fluid communication with the fuel conversion unit and configured to generate electric power with the at least a portion of the turbine feed.
A process for co-production of olefins and electric power comprising:
- separating a hydrocarbon feed into a light fraction stream and heavy fraction stream;
- generating electric power from at least a portion of the heavy fraction stream, wherein the at least a portion of the at least heavy fraction stream comprises between 35 wt % to 80 wt % of the hydrocarbon feed;
- and
- cracking at least a portion of the light fraction stream in a cracking reactor to produce an effluent comprising olefins, wherein the light fraction stream comprises between 20 wt % to the remaining portion of the hydrocarbon feed.
