Additives may be used to lower the set up point for bitumen thereby allowing it to be transported from place to place more easily. Additives useful for lowering the set up point of bitumen include alkylphenol formaldehyde resins and oxyalkylated alkylphenol formaldehyde resins; amines and esters; solvents; and combinations thereof.

Process for improving the transfer properties of bitumen

Heat exchanger fouling in organic chemical production processes may be reduced using an antifoulant additive. The antifoulant additive may have one component selected from the group consisting of an alkylphosphate ester, and an alpha olefin maleic anhydride copolymer; or it may have two components selected from the group consisting of a metallic overbase, an alkylphosphate ester, and an alpha olefin maleic anhydride copolymer, wherein at least one of the two components in not an overbase. An additive having three components: a metallic overbase, an alkylphosphate ester, and an alpha olefin maleic anhydride copolymer; is also within the scope of the disclosure.

Method for reducing fouling in furnaces

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.

Fouling of heat exchangers in chemical processing or oil refining systems is inhibited by incorporating into a petroleum derived stock an effective antifouling amount of a mixture of

Antifoulant compositions and methods

This invention relates to high internal phase ratio emulsions of colorant-containing fire suppressant concentrates which are non-settling and non-abrasive to high pressure, close tolerance pumps. These non-settling, non-abrasive concentrates can be prepared, stored, and diluted with water for use in both aerial and ground fire fighting.
