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 cracking hydrocarbon feedstock containing resid comprising: heating the feedstock, mixing the heated 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 which collect as bottoms and removing the liquid phase, separating and cracking the vapor phase, and cooling the product effluent. The process comprises at least two of the following conditions: (1) maintaining the bottoms under conditions to effect at least partial visbreaking; (2) reducing or eliminating partial vapor condensation during flashing by adding a heated vaporous diluent to dilute and superheat the vapor; (3) partially condensing the vapor within said flash/separation vessel by contacting with a condenser; (4) decoking internal surfaces and associated piping of the flash/separation vessel with air and steam; (5) utilizing a flash/separation vessel having an annular, inverted L-shaped baffle; and (6) regulating temperature in furnace tube banks used for heating by utilizing a desuperheater and/or an economizer. An apparatus for carrying out the process is also provided.
