Definitions
- the present invention relates to the field of explosives, specifically it relates to the preparation of ANFO using residual oils in replacement of Diesel 2.
- the present invention consists of a process for manufacturing an explosive (ANFO) using Ammonium Nitrate and residual oils, as well as the product obtained by this process.
- the ANFO is a high order explosive widely used in the mining industry to perform blasting because it is very safe, cheap and its components are easily achieved, in addition to the fact that the detonation of the ANFO is ultrasonic, and the blast wave is very powerful in relation to the amount to be used.
- ANFO a mixture of ammonium nitrate and petroleum-derived fuel
- its regular manufacturing procedure is to obtain the ANFO from the mixture of certain amounts of ammonium nitrate and fuel, which vary according to the length of the hydrocarbon chain of the fuel used. In general, the percentages range from 90% to 97% ammonium nitrate and from 3% to 10% fuel, being the most common to make ANFO based on a mixture of 94% Ammonium Nitrate and 6% Diesel 2.
- the Peruvian Technical Standard NTP 31 1 .278 "Explosives and Blasting Accessories, Ammonium Nitrate, ANFO grade, Requirements" defines the ANFO as a "product formed by the mixture of Ammonium Nitrate grade ANFO and fuel.
- the nominal composition in weight defined for the ANFO is: 94% of ammonium nitrate and 6% of diesel oil No. 2 ".
- diesel oil 2 is mixed with small amounts of residual oil equivalent to 60% of Diesel 2 and 40% of residual oil, reaching in some cases maximum of 50% Diesel 2 and 50% residual oil.
- residual oils have been used in the preparation of ANFO but always in a lesser proportion as an additional component in the fuel agent together with diesel oil 2.
- used oil recycled or In the production of ANFO there is a technical prejudice, since in the state of the art it is widely known that although used oils have also been used as fuel, they have the disadvantages of reducing the sensitivity to initiation and propagation, the speed of detonation and energy efficiency.
- the explosive ANFO comprises, in the typical case, 5-7% by mass of lubricating oil with respect to ammonium nitrate, no more than 2-3% of the conformation of the ANFO can be residual lubricating oil, the remaining 3- 4% requires being diesel or virgin oil or any other component (solvent) that dilutes it and allows its absorption by the ammonium nitrate which is the most important oxidizing component of this explosive.
- the present invention consists of a process for manufacturing ANFO based on residual oils in replacement of diesel 2 from the treatment of said waste oils by a previous process of double filtration and purification, as well as the product resulting from said process.
- the objective of this invention is to take advantage of the residual oil that is produced in the mines in large quantities, as the only combustible agent in the manufacture of ANFO, generating cost savings by completely replacing the Diesel 2 and additionally eliminating the existing risk by the withdrawal of waste oil mine and the negative impact it can generate on the environment if it is not properly used.
- the developed technology allows the filtration of 30,000 gallons of recycled oil in a mobile unit specially designed for these purposes, located in the same mine, which we will call filtering truck that will be responsible for purifying the residual oil obtained from the collection center through a system double filtering and then supply it to mixer trucks, instead of diesel 2, for the preparation of ANFO, which minimizes the environmental impact, takes advantage of the residual oil, generates greater security since the oil does not leave the mine and you save on costs when you stop using diesel 2.
- the filter truck removes the residual or recycled oil from the collection center. - Through a discharge hose the product enters through the manhole of the truck where the first filtering of 1 mm takes place.
- the filter truck pumps and pushes the residual oil to pass through two 30 micron serial filters (second filtering) and then through a gallon counter.
- the explosives factory truck integrates the double filtered residual oil to the ammonium nitrate to produce ANFO.
- the filter truck specially developed for this process is made up of the following components:
- Ventilation valve used for the entry of oxygen into the tank for the free flow of residual oil, pneumatically operated.
- - Hydraulic motor allows rotary movement to the residual oil pump.
- - Contometer allows to visualize the gallons of residual oil that are being sent to the mixer truck.
- Chassis used vehicle for the transfer of the components for the storage and pumping of the residual oil.
- the technical problem is solved by using the process of treatment and purification of waste oils through a double filtering process that allows its use as the only fuel component in the manufacture of ANFO, completely replacing diesel oil 2.
- This process of treatment and purification of residual oils requires, in turn, the intervention of a filter truck specially designed and implemented to meet the objectives of this procedure to have storage mechanisms, loading, filtration (at two different levels), mixing, pumping, cleaning, ventilation, suction, measurement and discharge.
- this innovative recycling truck is responsible for the purification of waste oils through a double filtering scheme at different times of the process and its pumping to the factory truck for mixing with ammonium nitrate once these Waste oils are suitable for that purpose.
- the present invention allows its implementation in the mine itself, without the need to transfer the residual oils, mitigating the environmental risks.
- the product resulting from this procedure has the same characteristics and properties as the regular ANFO, showing the following composition:
- This technology also allows eliminating the existing risk due to the removal of residual oil from the mine thanks to the implementation of an on-site filtering truck as an essential element that allows the use of 100% residual oil in the preparation of ANFO for blasting in mine.
- Figure 1 It shows a flow chart with the stages of the procedure and the place where each of them is performed.
- Figure 2 It shows a graph with the detail of the stages of the procedure in which it shows the supply of residual oil from the collection center, its entry through the filtering truck's manhole where the first filtering starts at 1 mm ( a), then the residual oil filter truck transports the residual oil to the points where the explosives factory trucks are located (b), while the residual oil filter truck pumps through two filters in series of 30 microns the oil waste to the fuel hopper of the explosives factory truck (c) so that finally the explosives factory truck integrates the residual oil to the ammonium nitrate to form
- Figure 3 Shows a plan view of the loading stage from the storage tanks to the filtering truck.
- Figure 4. Shows an elevation view of the loading stage from the storage tanks to the filtering truck.
- Figure 5 Shows a plant view of the discharge of the filter truck to the factory truck.
- Figure 6 Shows an elevation view of the discharge of the filtering truck to the factory truck.
- Figure 7. Shows the general plan.
- Figure 8 Shows a side elevation view of the filter truck with four manhole each with a 1mm filter (a), a mixer (b), a hydraulic motor (c) a cleaning valve (d) and a suction valve (and).
- Figure 9 Shows a plan view of the filtering truck.
- FIG 10. Shows a rear elevation view of the filter truck with the pump (a), the gauge (b), the suction valve (c), the double filter of 30 microns (d) and the swing coupling (e).
