Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to emulsifier compositions for petroleum products intended for the production of emulsions of the W2O type.

Recently, a method of emulsifying and dispersing 10 to 20 parts of water in heavy oil with Q has been implemented for the purpose of promoting complete combustion, reducing soot and NOx content in combustion gas, etc.

Various mixed compositions are used as emulsifiers, and for example, Japanese Patent Publication No. 52-37907 describes the use of a combination of an alkylbenzenesulfonate calcium salt and a non-ionoactive agent or a single alkylbenzenesulfonate magnesium salt. is suggesting.

The present inventor is not limited to specific uses such as heavy oil combustion methods, but can apply it to various purposes such as fuel oil additives, combustion improvers, concrete mold release agents, metal processing oils, metal cleaning agents, waterproofing agents, and polishing agents. Heavy oil, light oil, kerosene, fluid-9, which can economically produce stable W2O emulsions using relatively inexpensive raw materials and in small amounts without requiring strong mechanical stirring. We have discovered an emulsifier composition for petroleum products such as rough-in and paraffin wax.

The emulsifier composition of the present invention has a low content of inorganic compounds that remain as ash upon combustion, and does not contain any nitrogen compounds such as amines and amides that are sources of Nox.

Furthermore, the emulsifier composition of the present invention can be formulated by combining the following three components to provide a multi-purpose emulsified product with satisfactory practicality in terms of flammability, toxicity, odor, color tone, etc. Based on.

The first component is a nonionic activator, and is a polyoxyethylene alkylphenol ether prepared by adding 1 to 10 moles of ethylene oxide to nonylphenol or octylphenol, or a polyoxyethylene alkylphenol ether prepared by adding 1 to 1 mole of ethylene oxide to a natural or synthetic higher alcohol.
0 mol added polyoxine ethylene alkyl ether or a mixture thereof.

The second component is oleic acid or oleic acid, linoleic acid,
They are tall oil fatty acids containing divinitic acid, chain unsaturated higher fatty acids typified by naphthenic acid, cyclic higher fatty acids, or mixtures thereof.

The third component is an alkaline earth metal salt of dodecylbenzenesulfonic acid, i.e., a calcium salt or magnesium salt of a branched or linear alkylbenzenesulfonic acid as a raw material for synthetic detergent, or a by-product in the production process of these alkylbenzenes. Alkali or alkaline earth metal salts of sulfonic acids (referred to as synthetic petroleum sulfonates) of polyalkylbenzenes (referred to as L-heavy alkylates or alkylate bottoms with noalkylbenzene as the main component)
Alternatively, an alkali or alkaline earth metal salt of petroleum sulfonic acid (also referred to as mahogany soap) which is a by-product in the production process of fluid/matrix rough-in can be used.

Furthermore, the oil-soluble metal salts are not limited to the above-mentioned sulfur citrates, but alkaline earth metal salts of the second component, ie, carboxylic acids such as oleic acid, tall oil fatty acids, or naphthenic acids, can be used.

Therefore, the mixture of the second and third components can be prepared by separately obtaining the second component fatty acid and the third component fatty acid alkaline earth metal salt without mixing them or using sulfonic acid. , for example, by partial saponification with magnesium oxide, magnesium hydroxide, or magnesium carbonate.

These oil-soluble metal salts are generally very viscous and solidify or glue at room temperature, making them difficult to proportionately inject in a continuous emulsification process. Commercially available calcium alkylbenzene sulfonate tri approx.

The blending of petroleum solvents such as kerosene and rubent naphtha is undesirable from the viewpoint of deterioration of emulsifying power and flammability.

The present inventor has found that diethylene glycol, triethylene glycol, or tetraethylene glycol is an excellent solvent for the above three-component emulsifier composition, which does not cause a decrease in emulsifying power and does not impart flammability or a strong odor. I discovered that.

Tetraethylene glycol can be obtained from distillation bottoms produced as a by-product in the production process of diethylene glycol and triethylene glycol.
