Estimating the term…
A process for producing light alkanes and creating a flexible distribution system for those alkanes and related systems are disclosed. The process can include supplying a butane feed stream to a butane conversion unit to produce a light alkane output stream including at least methane, ethane, propane, and hydrogen, separating at least part of the light alkane output stream into separate streams of methane, ethane, and propane and distributing the separated streams as desired. The distribution of the separated streams can include sending the separated ethane and propane streams to downstream processing units which use them as feedstock. The butane containing feed and/or unreacted butane feed can include isobutane, which can be converted to n-butane and then further processed.
A system for generating light alkanes for general distribution and use, the system comprising:
The system of 1, wherein the separation unit is further operable to provide at least a portion of the separated H2 stream to the butane conversion unit.
The system of 1, wherein the separation unit comprises a distillation unit, a membrane unit, a propane separation unit, an ethane separation unit, a methane separation unit, a pressure swing adsorption unit, or any combination thereof
The system of 1, wherein the distribution network comprises at least one of a CH4 storage unit, a C2H6 storage unit a C3H8 storage unit, wherein at least one of the storage units is fluidly coupled to an input section and an output section of the distribution network.
The system of 1, wherein the distribution network is capable of distributing at least two of the CH4, C2H6, C3H8, and H2 streams and/or a C4H10-rich stream to the same downstream processing unit.
The system of 1, further comprising:
The system of 1, wherein the light alkanes output stream further comprises isobutane, wherein the separation unit is further capable of producing a stream comprising isobutane, the system further comprising:
The system of 1, wherein the butane conversion unit comprises a hydrocracking unit.
The system of 1, wherein the butane conversion unit comprises a hydrogenolysis unit.
A system for generating light alkanes, the system comprising:
A system for generating light alkanes, the system comprising:
