Bitumen production with solvent recovery system heat exchange techniques for bitumen froth treatment operations
Techniques are described for producing a bitumen product and recovering solvent from a solvent-diluted heavy hydrocarbon stream, which can have configurations and operation of an indirect heat exchanger to enhance performance. The system can have three solvent recovery stages. The indirect heat exchanger can have a location and operation to mitigate risks associated with exchanger failures. The solvent-diluted hydrocarbon stream can be preheated with a downstream solvent-depleted stream, and the pressure of the latter can be higher than that of the former to avoid solvent leaking into the hydrocarbon-enriched stream. The heat exchanger can be located in between the second and third stages, so that solvent leaked into the second stage output can be removed in the third stage so that the final product hydrocarbon stream can remain at low solvent contents.
