Definitions
- This invention relates to a method of preventing or re tarding parafiin build up on the walls of petroleum conduits or containers, thereby reducing or preventing clogging.
- the objective of applicants; invention is to prevent or retard the deposition of paraffin in petroleum conduits and containers.
- This invention can be used to prevent deposition ⁇ on the walls of containers and conduits with other solutions, suspensions, dispersions and emulsions than crude oil.
- This invention represents a substanital stride in the techniques of coping with paraflin in piping. It prevents parafiin deposition and saves "many man-hours of labor, when compared with the various paraflin-removal techniques. 1
- plastic-coated pipe It is an advance over plastic-coated pipe in that it can be used in the well itself; it can be easily applied to, pipe that is already in place and operating; and it can be much cheaper.
- Y is a molecule of a monovalent aliphatic carboxylic acid or cycloaliphatic carboxylic acid of from 1 to 10 carbon atoms, and a has a value from 0 to a value equal to the number of N atoms in 1) and from 99.75 to 90 mol percent, siloxane units of the formula 3 ASiO where A is a monovalent hydrocarbon radical with from 1 through 3 carbon atoms.
- the term consisting essentially of means that the copolymer is substantially as described but it can contain small amounts of other siloxane units which do not materially affect the property of retarding paraffin deposition.
- This copolymer can be made in the following Way:
- Y need not be present (1.e., a may equal 0) in order for the copolymer to be useful 1n applicants invention, nor, if it is present, is it necessary for every amine group to have a Y added to it.
- R can be any alkyl or alicyclic radical such as methyl, decyl, isobutyl, cyclohexyl, cyclopentyl, methylcyclohexyl, or octadecyl; or R can be any aminoalkyl radi etc.
- the Y group can consist of any of the defined carboxylic acids such as formic acid, acetic acid, isobutyric
- the material that is used by this invention is a silox'ane copolymer consisting essentially of from 0.25 to 10 mol percent, siloxane units of the formula Rf".
- n is an integer of a value from 0 through 2
- R is a hydrogen, alkyl, alicyclic, or aminoalkyl group
- R is a divalent hydrocarbon that separates the N and the Si atoms by at least three carbon atoms
- R" is a monovalent hydroacid, decanoic acid
- cyclohexyl carboxylic acid 4-methylcyclohexylcarboxylic acid, acrylic acid, methacrylic acid, butynoic acid, vinylacetic acid, crotoni c acid, and CH CH(CH )-;COOH.
- R has from 1 through 10 carbon atoms.
- the R" group can be any of the defined radicals such as methyl, hexyl, isopropyl,
- the A group can be methyl, ethyl, propyl, isopropyl, vinyl, allyl,
- Example 1 A polymer was made by reacting 2.7 mol percent of H NCH CH NH(CH Si(OMe) with 97.3 mol percent dimethylsiloxane with OH endblocks and an average chain length of 29 siloxane units and a small excess of acetic acid in an isopropanol solvent. The product was a copolymer of 2.7 mol percent 4
- Example 2 One-half gallon of the polymer described in Example 1 was added to a well by dump bailing at 2500 feet depth.
- One-half gallon of a Humble Oil Company corrosion inhibitor, known as Corexit 801 was also added to the well.
- Example 3 When copolymers of the following compositions are used to coat the inside of petroleum containers, or are added to the petroleum itself, effective retardation of the precipitation of paraffin on the container walls is noted:
- n is an integer of a value from 0 through 2
- A is a monovalent hydrocarbon radical with from 1 through 3 carbon atoms
- R is selected from the group consisting of H, alkyl, alicyclic, and aminoalkyl radicals
- R is a divalent hydrocarbon radical with at least 3 carbons atoms, the N atom and the Si being at least 3 carbon atoms apart
- R is a monovalent hydrocarbon radical with from 1 through 6 carbon atoms
- Y is selected from the group consisting of monocarboxylic aliphatic, and cycloaliphatic carboxylic acids of from 1 through 10 carbon atoms
- a has a value from 0 to a value equal to the number of N atoms in (1); in amount suflicient to retard deposition of paraflin on the walls of a container through which the petroleum is passed.
