Low dosage naphthenate inhibitors

Low dosage naphthenate inhibitors, such as a surfactant or hydrotrope, delivered into production fluids for contact with mixtures of oil and water, such as in a hydrocarbon producing formation, production equipment, or processing systems. Inhibitor compounds such as monophosphate esters and diphosphate esters exhibit surface-active properties that cause the inhibitors to self-associate at oil-water interfaces and inhibit interactions between organic acids in the oil with cations or cation complexes in the water. These compounds also inhibit aggregation of organic acid carboxylate salts that form when pH and pressure conditions are amenable to organic acid ionization. Preferred inhibitors do not form emulsions due to the formation of unstable mixed interface structures that result in coalescence of dispersed droplets. Naphthenate inhibitor compound dosages of less than 100 ppm can effectively inhibit naphthenate salts or other organic acid salts that can form precipitates or emulsions during crude oil production or processing.

Methods for inhibiting naphthenate salt precipitates and naphthenate-stabilized emulsions

Inhibiting naphthenate salts that can form precipitates or emulsions during crude oil production or processing. An effective amount of a naphthenate inhibitor, such as a hydrotrope, is provided into the production fluids for contact with mixtures of oil and water in the formation, the production equipment, or processing systems. It is believed that the naphthenate inhibitors, such as monophosphate ester or diphosphate ester, exhibit surface-active properties that cause the inhibitors to align and concentrate in a layer at the oil-water interface and thereby prevent interactions between organic acids in the oil phase with cations or cation complexes in the water. It is believed that the physical positioning and geometry of the naphthenate inhibitor blocks the growth of naphthenate salt crystals. However, it is preferred that the naphthenate inhibitors also avoid the formation of oil-in-water and water-in-oil emulsions.

Methods for reducing harmful emissions from a diesel engine

Emissions of pollutants from diesel engines are reduced by a combination of mechanical devices and fuel additives. In one series of embodiments, diesel emissions of NOx and particulates are reduced, simultaneously with gaseous hydrocarbons and carbon monoxide, by the combined use of exhaust gas recirculation or engine timing modification, with a particulate trap and a platinum group metal catalyst composition. In another embodiment, a multi-metal catalyst composition, comprising a combination of a platinum metal catalyst composition and at least one auxiliary catalyst metal composition, especially cerium or copper, is employed to provide catalyst metal to the exhaust system including a diesel trap to lower the balance point of the particulate trap (the temperature at which the rate of trap loading equals the rate of regeneration) while also lowering the emissions of carbon monoxide and unburned hydrocarbons. Data for platinum, copper and cerium catalysts establishes effective amounts. Tests also show selective maintenance of low oxidation of SO2 to SO3.

Method and apparatus for reducing harmful emissions from a diesel engine by post combustion catalyst injection

Emissions of pollutants from diesel engines (10) are reduced by a regimen for catalytically treating engine exhaust and, preferably, also the combustion of the fuel. The balance point of a diesel trap (30) is reduced to permit more efficient regeneration, preferably self-regeneration, while also reducing emissions of carbon monoxide and hydrocarbons by a combination of mechanical devices and fuel additives. The regimen requires the introduction of from 0.05 to 1 ppm of a platinum group metal catalyst (based on the volume of fuel combusted) into the particulates, by introducing at least half of the platinum group metal catalyst (50) directly into the hot exhaust gases (52, 20). Preferably, the platinum group metal catalyst is employed with a combustible organic liquid to aid in either progressively loading the trap (30) with the combustible organics or to combust in the hot combustion gases to facilitate burning of the particulates on the trap (30) for more effective regeneration. The judicious selection and use of an auxiliary catalyst metal (e.g., copper), preferably adding at least half of its total to the fuel as a fuel additive, is a preferred part of the regimen to achieve the lowest trap balance point.
