    摘要: A method includes receiving a measurement associated with a cloud point of a biofuel being produced in a refining system. The method also includes determining how to adjust the refining system based on a desired cloud point of the biofuel and the measurement associated with the cloud point. The method further includes outputting a control signal to adjust the refining system based on the determination. Determining how to adjust the refining system could include determining how to adjust an inlet temperature of a reactor in the refining system. The reactor could represent an isomerization reactor, and a heater could heat material entering the isomerization reactor. Determining how to adjust the inlet temperature of the reactor could include determining how to adjust operation of the heater. A model predictive control (MPC) technique could be used to determine how to adjust the inlet temperature of the isomerization reactor.

    摘要: Hydrocarbon conversion processes having a susceptibility to coke formation on the internal surfaces of processing equipment are improved by inhibiting the formation of coke with the use of a glass bead treatment for the metal surfaces. After treating with ordinary glass bead cleaning methods, metal surfaces are found to inhibit coke formation. The glass bead treatment is easily performed and, therefore, offers advantages over other chemical treatments for the deposition of silica on reactor internals.
