Abstract: A process and apparatus are provided for cooling gaseous effluent from a hydrocarbon pyrolysis furnace, the cooling conduit apparatus including: (i) an inner wall for contacting the effluent, the inner wall defining a bore extending a length of the cooling conduit, the inner wall including a perimeter opening along the bore; (ii) an outer wall external to the inner wall and substantially coaxial to the inner wall; (iii) a substantially annular cavity external to the inner wall and including at least a portion of the outer wall, the annular cavity fluidly and remotely connected to the perimeter opening, the annular cavity externally surrounding a perimeter of the inner wall, the annular cavity including at least a portion of the outer wall; and (iv) a peripheral channel extending around a perimeter of the inner wall, the peripheral channel providing a channel flow path that fluidly connects the annular cavity with the remotely connected perimeter opening along the perimeter of the inner wall.

Abstract: A process for cracking a hydrocarbon feedstock containing salt and/or particulate matter, wherein said hydrocarbon feedstock containing salt and/or particulate matter is partially desalted, e.g., by passing through a centrifugal separator, heated, then separated into a vapor phase and a liquid phase by flashing in a flash/separation vessel, separating and cracking the vapor phase which comprises less than about 98% of the hydrocarbon feedstock containing salt and/or particulate matter, and recovering cracked product.

Abstract: The present application is directed to an apparatus and method of managing transport of fluid commodities in a pipeline network. The method includes obtaining operational settings, which include equipment settings and measured parameters, associated with a pipeline network as a fluid commodity is transported through the pipeline network. From the operational settings, a recommendation is generated concurrently with the transport of the fluid commodity through the pipeline network to optimize at least one of the operational settings. The recommendation comprises revised equipment settings associated with equipment disposed along the pipeline network. The equipment settings in the recommendation may be based on empirical data from previous experience with the transport of fluid commodities through the pipeline network and/or based on theoretical data from modeling of the transport of the fluid commodity through the pipeline network.
