摘要： Antifoulant compositions and methods are used for inhibiting fouling on structural parts of a system exposed to a fluid hydrocarbon or petrochemical stream. Polyamine antifoulants are added to such systems. The polyamine antifoulants may be conjointly used with dispersants and/or fatty acids. The fatty acids have been found to reduce thermal degradation of the polyamine antifoulants.

摘要： The present invention includes methods for improving the operational parameters in primary fractionators which are experiencing diminished operation efficiencies due to deposits of polymerized hydrocarbon species. The invention comprises the step of adding a foam reducing amount of a foam reducing composition at the primary fractionator. A reduction in foaming is achieved whereby the operational efficiency of the process is improved based upon operation parameters including, but not limited to, liquid-gas contact ratio, product top temperature, pressure differentials, gasoline end point or combinations thereof.

摘要： A method for altering coke morphology in a delayed coking process of heavy oil is provided. An effective amount of oil dispersible or oil soluble metal salts of aromatic sulfonic acids and/or polysulfonic acids is added or contacted with the resid or heavy oil at a point before or after the step of heating the heavy oil to coking temperatures. The addition of additives facilitates the formation of shot coke and inhibits the formation of sponge coke.

摘要： A method of reducing asphaltene and particulate induced fouling during the thermal processing of petroleum oils utilizes resin extracts from HSDP crude oils to disperse and solubilize asphaltenes and disperse inorganic particulate contaminants such as salts and iron oxide. The extracts are essentially maltene fractions which may be separated from the HSDP crude by a process of extraction from a precipitated asphalt fraction using light paraffinic solvents such as n-heptane.

摘要： A heavy hydrocarbon oil, a substantial portion of which boils above 524.degree. C., is subjected to hydrocracking with a fractionated heavy oil recycle stream containing active additive particles. In the process, a slurry feed of (1) fresh heavy hydrocarbon oil feedstock and a heavy hydrocarbon recycle and (2) from about 0.01-4% by weight (based on fresh feedstock) of iron sulphate additive particles having sizes less than 45 .mu.m, is passed upwardly through a confined vertical hydrocracking zone. A mixed effluent is removed from the top of the hydrocracking zone, which is then passed through a hot separator vessel. From the bottom of the separator is withdrawn a liquid heavy hydrocarbon stream comprising heavy hydrocarbons and particles of the iron sulphate additive converted mainly to an iron sulphide phase. This separated liquid heavy hydrocarbon stream is fractionated to obtain a heavy oil which boils above 450.degree. C., containing the additive particles. The fractionated heavy oil containing the additive particles is then recycled to and mixing with the hydrocracking zone feed slurry in an amount up to 40% by weight of the combined feed slurry.
