Fluid recovery in chilled clathrate transportation systems

A pipeline system comprising:

• a transportation conduit configured to contain and flow gas hydrate slurry from a first geographical location to a second geographical location;
• a reclamation system located at the second geographical location and configured to recover a fluid component of the gas hydrate slurry;
• a recovered-fluid conduit configured to contain and flow the recovered fluid component from the second geographical location toward the first geographical location;
• and
• a combiner system configured to introduce the recovered fluid component into gas hydrate slurry subsequently flowing through the transportation conduit toward the second geographical location.

A method implemented in a pipeline system that transports flowable gas hydrate slurries from a first geographical location to a second geographical location, the method comprising:

• flowing gas hydrate slurry through a transportation conduit of the pipeline system from a first geographical location to a second geographical location;
• decomposing at least a portion of the flowed gas hydrate slurry at the second geographical location;
• recovering at least a portion of a fluid component released from the decomposed gas hydrate slurry;
• flowing the recovered fluid component from the second geographical location toward the first geographical location through a recovered-fluid conduit of the pipeline system;
• and
• introducing the recovered fluid component into gas hydrate slurry subsequently flowing through the transportation conduit toward the second geographical location.
