摘要： Systems and methods are provided for partial upgrading of heavy hydrocarbon feeds to meet transport specifications, such as pipeline transport specifications. The systems and methods can allow for one or more types of improvement in heavy hydrocarbon processing prior to transport. In some aspects, the systems and methods can produce a partially upgraded heavy hydrocarbon product that satisfies one or more transport specifications while incorporating an increased amount of vacuum gas oil and a reduced amount of pitch into the partially upgraded heavy hydrocarbon product. In other aspects, the systems and methods can allow for increased incorporation of hydrocarbons into the fraction upgraded for transport, thereby reducing or minimizing the amount of hydrocarbons requiring an alternative method of disposal or transport. In still other aspects, the systems and methods can allow for reduced incorporation of external streams into the final product for transport while still satisfying one or more target properties.

摘要： A submersible device submersible within an algae slurry contained within a pond of an algae bioreactor, the submersible device including a drive motor operable to actuate one or more driven devices that move the submersible device within the pond, a circulation device operable to circulate the algae slurry through the submersible device and discharge the algae slurry back into the pond from a discharge port provided on the submersible device, and a computer system that controls operation of the drive motor and the circulation device.
