Appl. No.:

09/957565

Inventors:

Joseph L. Stark - Richmond TX, US

US Classification:

436 55, 436 60, 436139, 7315218, 7315224, 73 6141

Abstract:

Disclosed is a method for transporting blended crude oils comprising the steps of; (a) admixing a first crude oil with a second, different crude oil to form a crude oil admixture; (b) determining a first value representing the content of unprecipitated asphaltenes in the admixture; (c) holding the admixture for a period of time at standard conditions; (d) determining a second value representing the content of unprecipitated asphaltenes in the admixture; and (e) either: (i) transporting the admixture if the second value is the same as or within a predetermined range of the first value; or (ii) taking remedial action to prevent asphaltene precipitation prior to transporting if the second value is outside a predetermined range from the first value. Also disclosed is a method for estimating the storage stability of stored crude oils and crude oil admixtures.

US Classification:

208108, 208181, 208298, 585864, 585833, 585866

Abstract:

Disclosed is a method for settling suspended finely divided inorganic solid particles from a hydrocarbon slurry using an additive. The additive comprises (a) a hydroxy-terminated polyoxyalkylate chain(s) containing polymer having at least one oxygen atom and at least one nitrogen atom and, optionally, (b) other components such as a solvent, an acid or mixtures thereof.

International Classification:

C10G 9/26

US Classification:

208125, 208131

Abstract:

Metal additives to hydrocarbon feed streams give improved hydrocarbon liquid yield during thermal cracking thereof. Suitable additives include metal overbases and metal dispersions and the metals suitable include, but are not necessarily limited to, magnesium, calcium, barium, strontium, aluminum, boron, zinc, silicon, cerium, titanium, zirconium, chromium, molybdenum, tungsten, and/or platinum, overbases and dispersions. Coker feedstocks and visbreaker feeds are particular hydrocarbon feed streams to which the method can be advantageously applied, but the technique may be used on any hydrocarbon feed that is thermally cracked.

Abstract:

Metal additives to hydrocarbon feed streams give improved hydrocarbon liquid yield during thermal cracking thereof. Suitable additives include metal overbases and metal dispersions and the metals suitable include, but are not necessarily limited to, magnesium, calcium, barium, strontium, aluminum, boron, zinc, silicon, cerium, titanium, zirconium, chromium, molybdenum, tungsten, and/or platinum, overbases and dispersions. Particularly useful metals include magnesium alone or magnesium together with calcium, barium, strontium, boron, zinc, silicon, cerium, titanium, zirconium, chromium, molybdenum, tungsten, and/or platinum. In one non-limiting embodiment, no added hydrogen is employed. Coker feedstocks and visbreaker feeds are particular hydrocarbon feed streams to which the method can be advantageously applied, but the technique may be used on any hydrocarbon feed that is thermally cracked.

Abstract:

The hydrolytic stability of magnesium overbased products is significantly improved by the addition or inclusion of a mixture or reaction product of an alkylphenol resin with a mixture of an alkenyl succinic anhydride and the acid thereof, and an alkyl amine. These magnesium overbased products are useful additives to fuel oils to improve their corrosion-causing tendencies. In one non-limiting embodiment, the alkylphenol resin is nonylphenol resin and the succinic anhydride is a partially hydrolyzed succinic anhydride having from 14 to 26 carbon atoms, along with the acid thereof. The mixtures and reaction products also serve as asphaltene inhibitors in the fuel oils.
