Description

COMPOSITION THAT NEUTRALIZES THE ACIDITY AND CORROSION CAUSED BY FLUIDS THAT DISSOLVE SCALE / DEPOSITS PRECIPITATED INSIDE CLOSED HEAT TRANSFER SYSTEMS. FIELD OF INVENTION The present invention relates to a “Composition” that neutralizes the acidity and corrosion originating from the use of acidic descaling products for dissolving mineral scale and organic deposits precipitated inside closed cooling or heat transfer systems, since it alkalizes the mixture of acid descaling agents and water, controls the corrosion of exposed metal components, without affecting industrial cooling systems composed of metals sensitive to corrosion and basic neutralization, such as copper, brass, bronze, aluminum, among others, used in general industry, particularly in the petroleum industry. BACKGROUND OF THE INVENTION Currently, the maintenance performed on heat transfer systems usually involves large amounts of man-hours in inefficient internal cleaning processes, and the mechanical integrity of said equipment is compromised by the use of acidic descaling agents that can cause internal corrosion if they are not properly neutralized, without any guarantee of effective cleaning. It is necessary to guarantee the long-term operational reliability of the equipment, as well as its mechanical integrity. This is achieved through the use of neutralizing agents combined with anti-corrosive and bactericidal elements, suitable for inhibiting and / or dispersing inorganic and organic scale. Based on the above, the aim is to use a neutralizing chemical agent, through a multifunctional product with neutralizing, anti-corrosive and bactericidal properties, applicable after the descaling process carried out in industrial heat transfer systems, where the characteristic formulations will be presented in the technology description.

They do not mention that a single "Composition" has the dual function of neutralizing fluids after the use of inorganic and organic descaling agents, in addition to being a multifunctional product at different concentrations, which is not achieved with conventional neutralizers that do not affect the internal components of heat transfer systems. Therefore, the novelty and inventive step of our invention are not affected, since it achieves a neutralizing effect on descaling fluids and does not damage metals such as copper, brass, bronze, aluminum, among others. DETAILED DESCRIPTION OF THE INVENTION The "Composition" is an organic chemical compound primarily composed of a mixture of liquids containing primary, secondary, and tertiary amines with their corresponding hydroxyl groups. The "Composition" acts as a weak base due to its lone pair of electrons on the nitrogen atom. It also contains surfactants, formulated from corrosion inhibitors and metal protectants. Furthermore, it is biodegradable, completely soluble in water, and miscible in most oxygenated organic solvents. The “Composition” does not accumulate in heat transfer systems, but is distributed relatively uniformly throughout the internal circuit creating a protective film against internal corrosion on the metal walls of the cooling systems, leaving no solids or residues after its application process. The “Composition” that neutralizes acidity and corrosion works as follows: From the start of the alkalization reaction of the low-pH water obtained after the treatment of heat transfer systems with acid descaling agents, the hydroxides present in the amines react with the protic acids to produce water and its corresponding salts, thus achieving the initial neutralization of the medium. For example, when the “Composition” reacts with a mixture of water and hydrochloric acid, a hygroscopic salt is formed with the HCl, ethanolamine hydrochloride: NÍCH2CH2OH13 + HCI > NÍCH2CH2OH13.HCI + H2O This type of reaction with a strong acid releases heat and is therefore exothermic. Based on this, the "Composition" neutralizes the organic acids present, adjusting the pH of the resulting solution to an alkaline medium. This facilitates the dissolution of the organic oils present in the resulting basic medium, which are not completely soluble in this liquid phase. en; / nn / eznz / R / vi The “Composition” does not promote bacterial growth, thanks to the alkaline environment created after its application, and is also compatible with water-based refrigerants used in industrial heat transfer systems, preventing the formation of corrosive acids after application. Application method 1. The circulation unit (see Figure 1), connections and hoses are installed at the inlets and outlets of the internal combustion engine cooling system. 2. After the application of the “Acid descaling agent that removes and dissolves scale / deposits precipitated inside closed heat transfer systems. 3. Wait for it to recirculate for one and a half to two hours, until you see a clean return in the collection tray. 4. Once the returns are clean, the pumping of the "Acid Descaling" product is stopped, and it is placed in drums for final disposal. 5. The pumping of the “Composition” is initiated, which neutralizes the acidity and corrosion originating from the use of acidic descaling products for the dissolution of mineral scale and organic deposits precipitated inside closed cooling or heat transfer systems, and is recirculated in the circulation unit (see Figure 1) for 30 to 90 minutes (time stipulated indicated in the laboratory results prior to service). 6. Subsequently, drinking water is pumped for 30 to 60 minutes. 7. The continuous circulation system is then uninstalled (again, see Figure 1). FORMULAS The main chemical elements that make up the chemical “Composition” technology, which neutralizes the acidity and corrosion caused by the use of acidic descaling products to dissolve mineral scale and organic deposits precipitated inside closed cooling or heat transfer systems, are listed below: Η ,N ΗΟ ΟΗ η=8, 10, 12, 14, 16, 18 R= -ch3. -ch2-ch3. -ch2-ch2-ch3 n=8, 10, 12, 16, 18 The examples are intended to illustrate the invention, not to limit it.

EXAMPLE No. 1 Taking and receiving samples where the “Composition” subject to the present invention will be evaluated. Samples were taken from heat transfer equipment. These samples were received in the laboratory and assigned a folio number according to the Logbook format FR-8015. Two types of samples were taken: aliquots from the cooling systems of internal combustion engines located in the storage area of ​​Observation Field No. 1 (Land Zone) and samples from the cooling systems of internal combustion engines located in Observation Field No. 2 (Marine Zone) (See Table No. 2). The present samples were registered to be analyzed at the laboratory level, and to experimentally demonstrate the functionality of the "Composition", so that it can later be applied in engines in the field.

Solid and liquid samples from Observation Field No. 1 (Land Zone) and Observation Field No. 2 (Marine Zone) underwent solubility tests with an acid descaling agent, simulating on a laboratory scale the procedure to be subsequently performed in the field, in order to observe its dissolution effectiveness and the acidity range in which the acid descaling agent acts. These tests were carried out to document that the acid descaling agent converts all the analyzed samples from a neutral to an acidic medium, and it is at this point that the "Composition" subsequently neutralizes the reaction medium. For this purpose, approximately 1 gram of each sample was weighed into 250 ml containers without prior treatment with any other type of solvent. Then, 25 ml of the "Acid Descaling Agent" was added to digest the sample at room temperature (21 °C) for 2 hours. The digested samples were subsequently filtered, oven-dried at 100 °C, cooled in a desiccator, and reweighed to constant weight. The weight loss as soluble matter in the "Acid Descaling Agent" was recorded (see Tables 3 and 4). The equation used to calculate the percentage of dissolution is as follows: %Dissolution (“Acid descaling”)=(P¡ (g)-(Pf (g)-Pfilter (g))) / (Initial weight (g)) Where: P¡: Initial weight of the sample. Filter: Weight of the dry filter, without sample. Pf: Final weight of the filtered sample, after drying. For the evaluation and interpretation of the results, the samples were separated according to their origin and sampling point, as was done in the evaluation of dissolved ions using spectrophotometric techniques. The maximum dissolution percentage reached was 72.12% for samples 28, 29, and 30, with average dissolutions of 70.33%, 70.55%, and 71.38%, respectively. Table No. 3.

The maximum dissolution percentage achieved was 69.20% for sample number 33, with an average dissolution of 66.73% for the group belonging to the "Oil Cooler" and 67.95% for the group belonging to the "Heat Exchanger."

For the study, two (2) samples were selected from the sample lot of Observation Field No. 1 (Terrestrial Zone) (27 and 28) and two (2) samples from the sampling lot of Observation Field No. 2 (Marine Zone) (33 and 35). The results are summarized in Tables No. 5, 6, 6-A and 6-B; the purpose is to validate the acidic pH levels with which the “Acid Descaling Agent” reacts. Table No. 5.

However, mathematical regression models were studied that are adapted to each of the detected reaction stages. These results may be influenced by the concentrations of the different chemical species present in the solid samples to be treated, starting from the initial acidity of the "Acid Descaling Agent," which denotes purely acidic media, which will be neutralized by the "Composition." EXAMPLE No. 3 Neutralization tests using the “Composition” that is the subject of the present invention. Neutralization tests were performed on solid and liquid samples from Observation Field No. 1 (Land Zone) and Observation Field No. 2 (Marine Zone). These tests involved reacting the samples with the remaining fluids of the "Acid Descaling Agent," simulating on a laboratory scale the procedure that would later be carried out in the field. The purpose was to observe the neutralization effectiveness and the acidity range in which the "Composition" acts. These tests were conducted to document that the "Composition" converts all analyzed samples from an acidic medium to a neutral medium, and that it is at this point that the "Composition" neutralizes the reaction medium without affecting metals sensitive to aggressive neutralizing agents. In order to determine quantitative monitoring parameters during field measurements, the pH parameter was monitored in some of the solid samples treated with the “Composition”, at 10-minute intervals until 30 minutes of reaction were completed. For the study, two (2) samples were selected from the sample lot of Observation Field No. 1 (Terrestrial Zone) (27 and 28) and two (2) samples from the sampling lot of Observation Field No. 2 (Marine Zone) (33 and 35).
