摘要： A process for cracking a light hydrocarbon feedstock containing non-volatile components and/or coke precursors, wherein a heavy hydrocarbon feedstock is added to the contaminated light hydrocarbon feedstock to form a contaminated hydrocarbon feedstock blend which is thereafter separated into a vapor phase and a liquid phase by flashing in a flash/separation vessel, separating and cracking the vapor phase, and recovering cracked product. The heavy hydrocarbon feedstock allows operation of the flash/separation vessel at a higher temperature, within the operating temperature range of the separation vessel.

摘要： A process for cracking a heavy hydrocarbon feedstock containing non-volatile components and/or coke precursors, wherein a stripping agent is added to the feedstock to form an enhanced hydrocarbon blend which is thereafter separated into a vapor phase and a liquid phase by flashing in a flash/separation vessel, separating and cracking the vapor phase, and recovering cracked product. The stripping agent increases vaporization of the volatile fraction of the heavy hydrocarbon increasing the maximum feedrate capacity of the furnace.

摘要： The invention relates to a method for processing asphaltene-containing feed to a pyrolysis furnace by raising the final boiling point of the feed/steam mixture to the pyrolysis furnace to ensure fouling occurs lower in the convection section where the mixture of air and steam can burn off fouling deposits during decoking operations. The final boiling point of the feed stream is increased by adding a heavy essentially asphaltene-free high boiling point hydrocarbon to the feed stream before the feed stream enters the convection section of the pyrolysis furnace, whereby said fouling occurs lower in the convection section.

摘要： An apparatus and process are provided for cracking hydrocarbons. Hot, cracked effluent is removed to a quench header where it is pre-quenched with an oil containing crackable components, e.g., 1000° F.+ (538° C.+) boiling range bottoms taken from a vapor/liquid separator, cracking the bottoms to more valuable products, e.g., steam crack naphtha. The overhead of the separator is fed to a cracker, and then quenched with a quenching oil.

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.
