Definitions

  • This invention relates to petroleum fuel additive formulations and particularly to such formulations in which an active component is dissolved in a carrier fluid and specifically when the carrier fluid is an aromatic acid ester, and to the use of such formulations in the production, processing, including refining, and use of petroleum Additives are often used in petroleum fuels to provide specific effects during processing or to provide particular properties in the fuel
  • Fuel additives are usually formulated as solutions in a suitable carrier fluid, which is commonly heavy aromatic naphtha (HAN - a mixture of mainly C g and C 10 aromatic hydrocarbons - predominantly t ⁇ methyl benzenes, diethyl benzenes and dimethyl ethyl benzenes) HAN is a very effective solvent and is readily and widely available.
  • the present invention is based on the discovery that certain esters of aromatic carboxylic acids, particularly benzoic acid, are very effective solvents for fuel additives and are environmentally much less objectionable than HAN
  • esters of aromatic carboxylic acids particularly benzoic acid
  • the present invention accordingly provides a petroleum fuel additive formulation which includes at least one petroleum fuel additive, particularly at least one paraffin wax pour point depressant and/or at least one dehazing agent dissolved in a carrier fluid including at least one compound of the formula (I) R 1 - (AO) n - OOC - (CH 2 ) m - Ph - (R 2 ) p (I) where
  • R1 IS a C- j to C-
  • AO is an alkyleneoxy group, particularly an ethyleneoxy or a propyleneoxy group, and may vary along the (poly)alkyleneoxy chain, n 0 or from 1 to 100, desirably 0, m is 0, 1 or 2, desirably 0, and
  • Ph is a phenyl group, which may be substituted with groups (R ) p .
  • each R2 IS independently a C-
  • the invention includes a method of treating a petroleum fuel, in which at least one petroleum fuel additive dissolved in a carrier fluid, including at least one compound of the formula (I), as defined above, is introduced into the petroleum fuel
  • the invention further includes the use of compounds of the formula (I), as defined above, as carrier fluids for petroleum fuel additives As is discussed below, desirably the carrier fluid is or includes /so-propyl benzoate
  • the petroleum fuel additive is, in particular at least one wax pour point depressant (dewaxer) and/or at least one dehazing agent
  • the invention includes a petroleum fuel additive formulation including one or more of at least one wax pour point depressant and/or at least one at least one dehazing agent, dissolved in a carrier fluid including at least
  • R 1 is a branched alkyl group, particularly a C3 to C ⁇ branched, such as a C3 to C5 secondary, alkyl group, e g an /so-propyl (prop- 2-yl), sec-butyl (but-2-yl), /so-butyl (2-methyl-prop1 -yl) and/or terf-butyl, or a 2-ethyl hexyl group, the branching reducing the ease with which the ester can be hydrolysed Esters with secondary alcohols are particularly useful in this regard and R ⁇ is thus especially a C3 to C 5 secondary alkyl group and very desirably an /so-propyl group
  • the carboxylic acid used in the ester can be a dihydrocinnamic acid or a phenylacetic acid, it is very desirably a benzoic acid i e desirably m
  • the esters used in the invention may include a (poly)alkyleneoxy chain, (AO) n in formula (I), between the carboxyl group and the group R ⁇
  • the (poly)alkyleneoxy chain is desirably a (poly)ethyleneoxy, a (poly)propyleneoxy chain or a chain including both ethyleneoxy and propyleneoxy residues
  • Esters of the formula (I) that can be used in the invention include ethyl benzoate, propyl benzoate, /so-propyl benzoate, sec-butyl benzoate, /so-butyl benzoate, tert-butyl benzoate, 2-ethyl hexyl benzoate and nonyl benzoate
  • these particularly useful esters are /so-propyl benzoate and 2- ethlyhexyl benzoate
  • Fuel additives are materials added to petroleum fuel materials e g diesel fuel, heating oil and gasoline, to provide particular effects such as pour point depression (dewaxing) and dehazing
  • the amount of the fuel additive included in the formulation is typically from 1 to 99, more usually from 5 to 90% by weight of the formulation Generally the amount of additive added to the fuel is within the range 1 to 5000 ppm by weight of the treated fuel, more usually from 5 to 2500 ppm Accordingly the amount of additive formulation added to the fuel is usually from 5 to 10000 ppm, more usually from 10 to 5000 ppm by weight of the treated fuel within these general ranges, the amounts for particular additives may vary as is described below
  • Middle distillate fuels are complex mixtures of hydrocarbon molecules including normal (straight chain) paraffins with carbon chains mainly from Cg to C28 but possibly with some compounds up to C3g
  • the heavier (longer chain) paraffins tend to precipitate wax crystals, typically as thin, flat, rhomboid plates and at very low temperature decreases these can grow to 0 5 to 1 0 mm across
  • Such wax crystals can directly cause fuel filter blockage and indirectly the wax crystals can build a gel structure in the fuel trapping liquid fuel between interlocking wax crystals so that as little as 0 5 to 1 % of precipitated wax may cause fuel solidification, thus blocking fuel lines etc
  • Paraffin wax pour point depressants are commonly added to the fuel to inhibit or prevent wax precipitation This resulting effect is similar to the removal e g by catalytic cracking, of waxes in refinery operations and is sometimes colloquially referred to as dewaxing
  • Such additives are usually presented as solutions in a carrier fluid Examples of suitable additives include
  • the concentration in the carrier fluid, or solvent is typically from 1 to 99%, particularly from 5 to 50% by weight of the total formulation and the formulations will typically include from 99 to 1 %, particularly from 50 to 5% of the carrier fluid by weight of the total formulation
  • the amount of pour point depressant included in an oil fuel is typically from 1 to 5000 ppm, particularly from 5 to 2500 ppm, by weight of the oil stream Accordingly, the addition rate of the pour point depressant formulation to the oil fuel will typically be from 5 to 10000 ppm, particularly from 10 to 5000 ppm, by weight of the total oil fuel
  • Fuels such as diesel fuel, heating oil and gasoline can contain minor amounts of water or aqueous material which separates during and/or after manufacture with even small amounts of water becoming visible as haziness in the fuel
  • Dehazers are added to remove the haze, probably either by solublizing or microemulsifying the aqueous material to give a clear, stable fuel, or by encouraging fuller phase separation of the water so it can be more easily removed form the fuel
  • the use of dehazers contributes to water being present as a separate phase where this is undesirable e g in storage tanks where separated water may lead to corrosion or in engines where it may cause corrosion or block fine nozzles or jets
  • the presence of detergent surfactants in fuel may act to stabilise emulsions of water in fuel thus increasing the tendency to form haze
  • Dehazers chemically typically have surfactant properties and examples include alkyl phenol formaldehyde resin alkoxylates and EO/PO, block or random, co-polymers, which usually have molecular weights of from 1000 to 5000, post reacted EO/PO block co-polymers, particularly post reacted with isocyanate materials such as MDI [4,4'-methyleneb ⁇ s(phenyl- ⁇ socyanate)] and polyamine, particularly alkylene, especially ethylene, diamine, alkoxylates, which usually have molecular weights of from 10000 to 100000, and polyol, particularly glycerol, alkoxylates, which can have a wide range of molecular weights from 1000 to 20000 or higher It is common to use combinations of two or more dehazer materials to suit particular conditions in an oil stream, e g combinations of coalescence and flocculation enhancing agents
  • the concentration of dehazer components in the carrier fluid, or solvent is typically from 10 to 90%, more usually from 15 to 85%, particularly from 25 to 80% by weight of the total formulation
  • dehazer formulations of the invention will typically include from 90 to 10%, more usually from 85 to 15%, particularly from 75 to 20% of the carrier fluid by weight of the total formulation
  • the amount of dehazer included in an oil fuel is typically from 1 to 500 ppm, particularly from 5 to 150 ppm, by weight of the fuel
  • the addition rate of the dehazer formulation to the fuel will typically be from 5 to 1000 ppm, particularly from 10 to 300 ppm, by weight of the total fuel
  • the invention includes a fuel additive formulation which includes at least one fuel additive agent, particularly at least one paraffin wax pour point depressants and/or at least one dehazing agent, dissolved in a carrier fluid including at least one compound of the formula (I) as defined above, in particular where the carrier fluid is or includes /so-propyl benzoate
