    摘要： The present disclosure provides a process for treating a hydrocarbon feedstock comprising: (a) feeding the hydrocarbon feedstock at a linear velocity equal to or less than 0.9 m/s to a first preheating zone in the convection section of a steam cracking furnace; (b) preheating the hydrocarbon feedstock in the first preheating zone to vaporize less than 99 wt. % of the hydrocarbon feedstock to form a vapor-liquid mixture; (c) separating at least a portion of the vapor-liquid mixture to form a vapor fraction and a liquid fraction; and (d) feeding at least a portion of the vapor fraction to the steam cracking furnace.

    摘要： A process for feeding or cracking heavy hydrocarbon feedstock containing non-volatile hydrocarbons comprising: heating the heavy hydrocarbon feedstock, mixing the heavy hydrocarbon feedstock with a fluid and/or a primary dilution steam stream to form a mixture, flashing the mixture to form a vapor phase and a liquid phase, and varying the amount of the fluid and/or the primary dilution steam stream mixed with the heavy hydrocarbon feedstock in accordance with at least one selected operating parameter of the process, such as the temperature of the flash stream before entering the flash drum.

    摘要： A process for reducing the rate of increase in pressure drop across a furnace convection section, the furnace convection section having a temperature profile. The process includes the steps of establishing a ratio of total dilution H2O to feedstock for the system, injecting a first portion of the total dilution H2O in the form of water into the convection section of the furnace, injecting a second portion of the dilution H2O in the form of steam into the convection section of the furnace, wherein a ratio of dilution H2O in the form of water to dilution H2O in the form of steam is established and varying the temperature profile across the convection section of the furnace by adjusting periodically the ratio of dilution H2O in the form of water to dilution H2O in the form of steam. A similar technique is conducted during decoking to remove asphaltene coke starting from the lower convection section upward. This upward decoking is accomplished by initially using more H2O in the form of water, then as the decoke proceeds reducing H2O in the form of water while increasing H2O in the form of steam.
