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.
