摘要： Corrosion induced by the presence of naphthenic acids in hydrocarbon fluids, particularly where such fluids are at elevated temperatures, may be inhibited or controlled through use of corrosion inhibiting compositions comprising a combination of a minor portion of a phosphorus-based constituent and a major portion of a sulfur-based constituent, nitrogen-based constituent, or combination thereof. In another embodiment the sulfur-based constituent and/or nitrogen-based constituent may be used without any phosphorus-based constituent. Where the compounds are appropriately selected, the compositions may inhibit corrosion to a degree comparable or nearly comparable to the inhibition provided by an equal amount of some conventional phosphorus-based compounds alone, but are significantly less likely to impair catalyst activity in downstream cracking and refinery operations.
摘要翻译：在烃流体中，特别是在这些流体处于升高的温度下，环烷酸的存在引起的腐蚀可以通过使用腐蚀抑制组合物来抑制或控制，所述腐蚀抑制组合物包含少量部分磷基成分和主要部分硫基成分，氮基成分或其组合。在另一个实施方案中，可以使用硫基组分和/或氮基组分而没有任何磷基组分。当适当选择化合物时，组合物可以将腐蚀抑制在与等量的一些常规磷基化合物单独提供的抑制相当或几乎相当的程度上，但是显着不太可能损害下游裂解和炼油中的催化剂活性操作。

摘要： Exhaust emissions resulting from the combustion of hydrocarbon fuels in compression ignition engines may be reduced using a homopolymer that may be polyisobutylene, polypropylene, and/or hyperbranched polyalpha-olefins. Optionally, an alkyl nitrate such as 2-ethylhexylnitrate (2EHN), and/or a peroxide, such as hydrogen peroxide, may also be used together with the homopolymer. Both NOx and particulate matter emissions (PM) may be reduced using ppm quantities of the additive compositions; alternatively, NOx emissions may be lowered or reduced while PM emissions do not substantially increase.

摘要： 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.

摘要： Amine and amine blend compositions neutralize acid environments in distillation overheads of hydrocarbon processing facilities. The neutralizers are composed of certain combinations of amines which are relatively stronger bases and more resistant to hydrochloride salt formation. The amines, when blended together, provide greater neutralization of condensed water present without increased potential for corrosive hydrochloride salt formation.

摘要： Corrosion of iron-containing metal surfaces in a hydrocarbon fluid having a temperature of from about 175.degree. C. to about 400.degree. C. and containing a corrosive amount of naphthenic acid is inhibited by adding to the fluid or to a feed therefor, in a total additive amount sufficient to effect corrosion inhibition in said fluid, one or more thiophosphorus compound, a salt thereof, an alkyl or aryl ester thereof, an isomer thereof, or some combination of the foregoing, thereby to effect inhibition of naphthenic acid induced corrosion in the fluid.
