ABSTRACT A method is disclosed for improving the transpor- tability of a hydrocarbon composition by passing an in- fluent feed stream of composition into a downcomer to provide a hydrostatic column of fluid. The influent stream is heated by heat exchange with an effluent product stream wherein at least one of the streams is in turbulent flow. The feed stream is pressurized by the hydrostatic pressure head to a reaction pressure of at least about 1000 psi. The heated and pressurized feed stream is contacted with an active heat source in a reaction zone to increase the temperature of the feed stream to a reaction temperature of between about 300°C and the coking temperature of the hydrocarbon composi- tion. The temperature differential between the active heat source and the feed stream in the reaction zone is maintained at less than about 30°C to provide a treated effluent stream which is brought into heat exchange contact with the influent stream. The treated composi- tion has a lower viscosity than the feed composition.
