Description

"HYDROCARBON MICROENCAPSULATED PROCESS"? BACKGROUND OF THE INVENTION This invention arises from the current needs of coating with a reliable, efficient and effective ecological technology that helps to prevent and solve the problems of pollution due to hydrocarbon residues. Silicates have been widely used over time in many different ways including ecological, but without giving the desired results. So based on this, the formulation of A.B.E. PETROCHEM and S.S. PETROCHEM Emulsifiers, like silicates, have been widely used in many fields of the /. industry, so the important thing was to develop a specific formula to break the surface tension of hydrocarbons and also react with a silicate, in order to definitively isolate the polluting residues of hydrocarbons. In this way the formulas of A.B.E. PETROCHEM and S.S. PETROCHEM. Of great importance is also the application process of these chemical products since without the technique described in DESCRIPTION OF THE INVENTION it is not possible to achieve the results of microeacapsular in definitive form to the hydrocarbon residues. On February 20, 1997, the Mexican Institute of Industrial Property was requested through * _ of the Department of Searches, Documentary Fund and Microfilm a national and international technical search regarding the hydrocarbon microencapsulation process. This search resulted tecaüzación of 20 references, but none is related to the characterizations of the process of microencapsulation- hydrocarbons, nor with the characterizations of the formulation of A.B.E.

PETROCHEM and S.S. PETROCHEM DESCRIPTION OF THE INVENTION The hydrocarbon microencapsulation process is a chemical treatment that turns hazardous hydrocarbon residues or contaminated with hydrocarbons into non-hazardous and reusable; It is an ecological technology. There are other similar technologies that have not given the results obtained with the hydrocarbon mkroencapsulation process, mainly due to large differences in the formulation of the chemical products used and their application process. The invention consists of: The formulation of two chemical products as well as the process of applying them to hydrocarbon residues or soils contaminated with hydrocarbons, regardless of the type of hydrocarbon, for the purpose of confining hydrocarbon residues in an oxide microcell. of silicon, pure, amorphous, inert, impermeable and insuppressible, formed by the instant chemical reaction of ABE PETROCHEM and dd S.S. PETROCHEM and the correct application of these through the process described here. This microcell avoids all contact of the polluting elements with the environment.

Weight per drum from 595 to 625 pounds.

APPLICATION PROCESS. The hydrocarbon microencapsulation process is carried out with a ribbon mixer. The batten mixers are designed to mix with great efficiency and for this they are used in the preparation of medicines and in the preparation of baby food. The material to be treated (waste contaminated with any type of hydrocarbons or hydrocarbon residues) is weighed. In a 173-ft1 mixer of capacity it can be processed from 1, 000 to 1,500 kilograms depending on the characteristics of the material. Then let us add 1,000 or 1,500 kilograms of material to the mixer. Step 1. The material is homogenized for 5 minutes, a sample is taken to run a retort analysis, and pH is also measured.

The retort analysis results in a percentage of hydrocarbons in the sample and consists of distilling the hydrocarbons and water present. Step 2. Once known d percentage of hydrocarbons and pH, the chemical products A.B.E. are dosed. PETROCHEM and the S.S. PETROCHEM. As an example of dosage, we can mention the following: If the percentage of hydrocarbons is between 35 and 40, the dosage of A.B.E. PETROCHEM should be 5 gallons per thousand kilograms, and the dosage of S.S. PETROCHEM should also be 5 gallons per thousand kilograms because the molar ratio between A.B.E. PETROCHEM and the S.S. PETROCHEM is one on one. The aforementioned dosage was found to be optimal by means of the trial and error method and consequent analysis of the results. If d% - * ^ of hydrocarbons is between 41 and 50 the dosage dd A.B.E. PETROCHEM should be 8 gallons per thousand kilograms and k) both the dosage of S.S. PETROCHEM will also be 8 gallons per thousand kilograms. Step 3. The first chemical that is applied is A.B.E. PETROCHEM, and is done by spraying with an electric pump with HP% engine and at an expense of 3 gallons per minute The A.B.E.

PETROCHEM has the characteristic of emulsifying any chemical species of hydrocarbon, that is to say, it acts in all d range of BHL (Hydrophilic Lipophilic Balance) so when contacting the hydrocarbon it emulsifies it and traps it permanently surrounding it at a microscopic level. Step 4. After 15 or 20 minutes of mixing, measure pH d which should be in d acid range, if not, add more A.B.E. PETROCHEM until obtaining the acid value. 20 Step 5. Once in the acid range, proceed to apply S.S. PETROCHEM also for asperete and with an electric pump with HP V * engine and at an expense of 3 gallons per minute. The S.S. PETROCHEM reacts instantly with the A.B.E. PETROCHEM that previously trapped the polluting hydrocarbon, and it is at the moment of this reaction that the microcell of silicon oxide is formed. 25 Step 6. After 15 minutes of mixing, measure the pH d which should be in the range of 7.0 to 8. 5, u d value is in that range d material is treated and ready to be unloaded from the ribbon mixer. If this is not the case, more S.S. PETROCHEM, with mixing, until the pH value is in d foran or indicated. It is important to mention that d total volume at the end of treatment, only increases from 10 to one % maximum, this is: 5 1,000 kilograms of material to be treated will become, by the addition of chemical products, 1,010 kilograms or 1,020 kilograms of non-hazardous material susceptible to be rendered useless without damage to the environment. Step 7. Once the treated material is discharged, it is placed in a sampling area. ** ^ Step 8. In its opportunity, the following is analyzed: a) Water in oil by the EPA OIL IN WATER method. b) CRETTB in accordance with the Official Mexican Standards. This ensures that the treated material is no longer a hazardous waste. c) Edaphic analyzes that verify the content of chemical elements and physical characteristics adequate to make the treated material a culture medium. We attach to this document copies of CRETIB analysis certificates made in accordance with the Official Mexican Standards for samples of hazardous hydrocarbon residues treated by the hydrocarbon microencapsulation process. We also attach a copy of the opinion issued by the Laboratory of Edafocli atología of the Center for Biological Research of the Autonomous University of the State of Mordos in order to demonstrate the effectiveness of the process. Therefore, it can be stated that the characteristics of this hydrocarbon microencapsulation process together with the formulation of the mentioned chemical products have not been achieved by any other similar technology.
