1. Field of the Invention
The present invention relates to processing of fuel, and more particularly to dewatering agents for fuels and cleaning agents for drill cuttings and dewatering and dispersing agents for biofuels.
2. General Background of the Invention
Processing of fuel often involves adding to the fuel dewatering agents for fuels and dewatering and dispersing agents for biofuels. Cleaning agents are often used to clean drill cuttings.
The present invention includes a composition which can be useful for cleaning drill cuttings, processing slop oil, and processing biofuels. The composition preferably includes a demulsifier, a co-additive for demulsifier, a solvent and coupling agent and antifoaming agent, a very powerful demulsifier, a solvent, a chelating dispersant, a surfactant, a fluorinated surfactant, and a dispersant which is an oil soluble and water dispersible anionic surfactant. Preferably there are as well multiple surfactant—degreasing agents (particularly when the composition is used to clean drill cuttings).
Preferably, the demulsifier is at least one from the group consisting of citric acid, acetic acid, ascorbic, formic, other carboxylic acids, sulphamic acid, phosphoric acid, sulfuric acid, and mixtures thereof, the co-additive for demulsifier is at least one from the group consisting of dodecyl benzene sulphonic acid, toluene sulphonic acid, toluene sulphonic acid, xylene sulphonic acid, and any other alkyl benzene sulphonic acid, and mixtures thereof, the solvent and coupling agent and antifoaming agent—hydrotrope is at least one from the group consisting of butyl cellosolve and any other preferably non-toxic alkyl glycol ether, and mixtures thereof,
the very powerful demulsifier is at least one from the group consisting of on the one hand diisopropylnaphthalenesulphonic acid (35-70%), sodium dodecylbenzenesulfonate (10-30%), 1,2,4-trimethylbenzene (5-15%), sulphuric acid (0.5-5%), xylene (0-3%), cumene (0-3%) and on the other hand other alkyl, di-alkyl, tri-alkyl napthlalene sulphonic acids, and mixtures thereof, the solvent is at least one from the group consisting of pine oil and any other terpene type of oil, and mixtures thereof, the chelating dispersant chelates Fe, Al, Ca from about 100 ppm to less than 10 ppm—moves Fe, Al, Ca from oil to water, and comprises an oil-water soluble copolymer of partially sulfonated, maleic anhydride and polystyrene, 25% active, the surfactant lowers surface tension and is at least one from the group consisting of alcohol ethoxylate and any other non-ionic ethoxylated surfactant, and mixtures thereof, the fluorinated surfactant lowers surface tension is at least one from the group consisting of on the one hand 40% fluorosurfactant, 30% isopropyl alcohol, and 30% water and on the other hand a Capstone fluorinated surfactant, such as Capstone N35 or Capstone N65-fluorinated surfactant, which are 25% active, so 4× the amount should be used, and mixtures thereof, the surfactant—degreasing agents are at least one from the group consisting of nonylphenol ethoxylate, POE-4, nonylphenol ethoxylate, POE-6, and nonylphenol ethoxylate, POE-8, and mixtures thereof, the dispersant is an oil soluble and water dispersible anionic surfactant which drops char content from around 2000 ppm to less than 10 ppm and is at least one from the group consisting of isopropylamine dodecyl benzene sulfonatesand other oil soluble and water dispersible anionic surfactants, including other isopropylamine dodecyl benzene sulfonates, and mixtures thereof.
In the above table, POE is polyoxiethylene.
To make the Malcera 1507AK product, one blends as follows (with preferably constant stirring):
Preferably, the citric acid is always the first ingredient in the reactor. Preferably, EB, Biosoft 101, and C-4100 are added before Versa TL-4. After that, the ingredients can be added in any order. The goal is to keep all components properly blended without separation as the blending occurs.
However, it is possible to mix ingredients other than citric acid together, then add that mix while stirring to the citric acid (in such a case more EB might be needed).
Malcera sells the above product as Malcera 1507AK.
Malcera 1507AK (optionally without Makon 4, Makon 6, and Makon 8) (or a version with ingredients from columns 1 and or 2 of Table 1) can be used to treat slop oils and tank remnants or sludges to knock out water and to disperse the hydrocarbons into diluents, and to drop solids out of these products. This is usually performed at about 150-200 degrees F. and the concentration is usually 1,000-2,500 ppm.
Malcera 1507AK (or a version with ingredients from columns 1 and or 2 of Table 1) can be used to treat drill cuttings to reduce water content. This is usually performed at about 100 degrees C. and the concentration is usually 5,000-10,000 ppm. The drill cuttings are typically coated with oil based drilling mud emulstions.
Malcera 1507AK (optionally without Makon 4, Makon 6, and Makon 8, but preferably in approximately the amounts listed in column 7 of Table 1) (or a version with ingredients from columns 1 and or 2 of Table 1) can be used to reduce water content and solids content in a biofuels mixture made from the pyrolysis of wood to yield a very clean oil. This clean oil can then be hydrotreated to make gasoline and diesel. When used in a biofuels mixture, typically 500-1000 ppm of Malcera 1507AK is used in the biofuels mixture. The typical temperature is about 150 degrees F. Malcera 1507AK knocks out water so that less than 99.9% of the biofuels mixture is water. A desalter then takes out last up to 0.1% water. Another useful product is commercially available from Malcera as product 507AIG. 507AIG can include the following preferred ranges of components:
In use, the doseage ranges could be as follows:
The present inventor recently combined 1507AK and 508MM into a new single product by using a coupling agent from 1057AK (Biosoft 101). The new single product to be sold commercially as Malcera 507AIG, helps to process petroleum crude oils and biofuels with no rag layer.
To make the Malcera 507AIG product, one blends as follows (with preferably constant stirring):
Then continue to stir for 4 to 5 hours at ambient temperature. Preferably, the 508MM is always the first ingredient in the reactor. The diesel or any liquid petroleum hydrocarbon of said mixture may be omitted by contiguously heating the mixture to a temperature of 170° F.
The chemical blend of Malcera 507AIG preferably comprises the following component ranges: 15 to 30% of 508MM, 5 to 20% of Diesel, 10 to 25% of Stepan Biosoft 101, 25 to 75% of 1507AK.

This formulation of Malcera 507AIG may be used to break an emulsion before cleaning drill cuttings and can also be used as a substitute for Malcera 1507AK.
Another optional blending formulation of Malcera 507AIG has the following composition: 20% 508MM, 15% diesel or any liquid petroleum hydrocarbon, 5% of Stepan Biosoft 101, and 60% 1507AK.
