Here is a list of other AN accidents that you could research on your own to find out about other scenarios that can lead to detonations. It is known that ammonium nitrate decompose exothermically when heated to form nitrous oxide and water. You will use 1 mL of solution in many of the reactions; estimate this by drops (typically 12-15 drops from the reagent bottle dispenser) or by measuring 1 mL once in your graduated cylinder and then transferring it to a test tube to determine how far it fills the test tube. Concentrated ammonium nitrate solution is then sprayed into the granulator along with a regulated quantity of limestone powder and the recycle fines from the screens. In addition to the production of toxic gas, the energy release is reduced. On the Thermal Decomposition of Ammonium Nitrate. Web1. A fiberglass lid One reason that ammonium nitrate is so explosive is that it contains in the same molecule both a fuel, in the form of the ammonium ion, and a strong oxygen- producing agent, nitrate. Duress at instant speed in response to Counterspell. These charges allow water molecules to tightly adsorb the clay surfaces (hydrophilic), ensuring that water is available to create the soil solution. In Beirut we saw that there was already a fire burning for a significant amount of time before the explosion, as well as a smaller explosion that occurred < 30 seconds before the main one. <> It decomposes at 230oC producing nitrous oxide gas (N 2 O) and water vapour. decomposition reactions of FGAN can only be assumed. (3 marks) Ques. The following reactions are performed, and the results are shown below. What role does ammonium play in the explosion of ammonium nitrate? releases huge amounts of energy.[]. Give a balanced equation for the decomposition reaction. Record your observations on the data page as you complete each reaction. Once ammonium nitrate starts to decompose, a runaway reaction may occur as the heat of decomposition increases. Note: Method 1 is of less importance now and used less because formaldehyde can be a safety hazard if not used properly. Gases thus produced include hydrogen sulfide, sulfur dioxide, carbon dioxide and ammonia. Thermodynamic properties of substances. According to Ref.2, during the explosion, following exothermic reaction would take place (hydrocarbon is represented by $\ce{CH2}$): $$\ce{3NH4NO3 + CH2 -> 3N2 + 7 H2O + CO2} \quad \Delta H = \pu{-4017 kJ/kg} \tag1$$. Its simplicity of production and low cost, about $170/tonne in the U.S. in 1995, add to its product appeal. Ammonium, nitrate, and phosphorus are plant-availabe nutrients that are found in wastewater and are frequently associated with excessive algae growth in surface waters. It is predominantly used in agriculture as a high-nitrogen fertilizer and is also used as a component of explosive mixtures in mining, quarrying, and civil construction. WebAmmonium nitrate melts at 337 deg F (170 deg C) and begins to undergo decomposition when molten. From: Encyclopedia of Analytical Science (Second Edition), 2005, P.S. drop pipe from the elevator mechanism) was followed by about 5 to 6 minutes of intense radiant heating expected when FGAN undergoes thermal decompositionsuch as NO2, O2, and HNO3 as wells as fuelrich smoke and pyrolysis products off-gassing from the molten FGAN. Fertilizer value is derived both from the high total nitrogen content (33%) split between fast acting nitrate nitrogen and the slower acting ammonium nitrogen, plus the ease of marketing and handling a solid product. The additional ventilation caused a marked decrease in dark smoke and probably was accompanied by a In some cases, solutions may be blended for marketing as liquid fertilizers. As for the question whether the disaster of Beirut was an deflagration or a detonation: which term is applicable depends solely on the rate of decomposition and the resulting velocity of the front. Interestingly, ammonium nitrite ($\ce{NH4NO2}$) is far more labile and very hard to prepare as the two ions tend to react to form nitrogen gas and water even in solution at room temperature. For reactions involving metals, use just one piece of metal. It is also used in explosives (especially as an oil mixture) for blasting rocks and in mining. J.H. Soil chemistry is the interaction between soil solution and solid phase. The mixing equipment on the truck requires regularcalibration, and even if calibrated, sometimes it can malfunction. might have melted the cover, and FGAN remnants could have been in the pit. NH 4 NO 3 : molecular weight = 80.05 g/mol. FGAN. What are the other chemical substances that are formed in the process of making ammonium nitrite? High-density prills, granules, and crystals are used as fertilizer, while ammonium nitrate grains are used solely in explosives, and low-density prills that are small aggregates or globules of the materialmost often a dry sphereformed from a melted liquid. Production of Ammonium Nitrate and Urea in Selected Countriesa. Ammonium nitrate is composed of two polyatomic ions identify the different type(s) of bonding within its structure. Examples are shown in Figures 5-7. Rangi CS GO. It was at a seaport, too, meaning there were probably a lot of nearby things to act as fuel sources. In this review data from the literature on thermal decomposition of ammonium nitrate (AN) and the effect of additives to their thermal decomposition are summarized. Use 1 mL of each solution unless otherwise specified. What are the other chemical substances that are formed in the process of making ammonium nitrite? Once ammonium nitrate starts to decompose, a runaway reaction may occur as the heat of decomposition increases. The molten FGAN at the WFC likely came in contact with contaminants that were stored in the fertilizer $$\ce{NH4NO3 -> N2O + 2H2O } \quad \Delta H = \pu{-59 kJ/mol} \tag3$$, $$\ce{NH4NO3 -> 1/2N2 + NO + 2H2O } \quad \Delta H = \pu{-2597 kJ/mol} \tag4$$, $$\ce{NH4NO3 -> 3/4N2 + 1/2NO2 + 2H2O } \quad \Delta H = \pu{-944 kJ/mol} \tag5$$, $$\ce{2NH4NO3 -> 2N2 + O2 + 4H2O } \quad \Delta H = \pu{-1057 kJ/mol} \tag6$$, $$\ce{8NH4NO3 -> 5N2 + 4NO + 2NO2 + 16H2O } \quad \Delta H = \pu{-600 kJ/mol} \tag7$$. How much ammonium nitrate will be required for each gallon of fuel oil to make an oxygen-balanced batch of ANFO? Things like that did happen before. Don't forget to note the color and composition of the residue left on the tongs. To write balanced equations for the reactions studied. There were also flashes and bangs and a lot of other stuff going on there (reportedly there were fireworks stored in the same warehouse). Arrhenius plots for these ammonium nitrate composite systems were constructed. Obviously, nitrate leaching represents a loss of available nitrogen from the plant-soil system. If no reaction is expected, indicate this and explain why no reaction is expected. That was not ammonium nitrate (it was ammonium perchlorate, another oxidizer), but the possible scenarios are similar and it also illustrates the complexity of those kinds of situations. As an example, potassium chlorate decomposes when heated to yield potassium chloride and oxygen gas. Heating also poses a danger: ammonium nitrate decomposes at around 230C, and can explode when heated to between 260300C if its confined. Balancing Strategies: In this decomposition reaction, NH4NO3 is breaking apart (decomposing) into N2 + O2 + H2O. To perform and observe the results of a variety of chemical reactions. eyewitness accounts and photographic evidence (Figure 40). The solubility behavior of the ions that you will be using is summarized in the following table: Group IA and Ammonium compounds are soluble. Steady-state Reaction But apparently there have been accidental explosions involving just the "fertilizer". @JasonC There are many factors, not just heat. The sulfuric acid can be titrated with sodium hydroxide to determine the amount of ammonium sulfate present. the surface of the FGAN pile. 2217 Earth and Engineering Sciences Building, University Park, Pennsylvania 16802 Ammonium nitrate in UAN can be determined by this method since the urea will not react. gases like nitrogen oxides. NH 4 NO 3: molecular weight = 80.05 g/mol CH 2: molecular weight = 14.03 g/mol The ideal mixture, i.e., the oxygen-balanced mixture, consists of 3 moles of ammonium nitrate and one mole of fuel oil. A small but potentially significant difference between urea and nitrate-containing fertilizers is that the peak concentration of nitrate in soil is likely to be less with urea. WebAmmonium nitrate | NH4NO3 or H4N2O3 | CID 22985 - structure, chemical names, physical and chemical properties, classification, patents, literature, biological activities, safety/hazards/toxicity information, supplier lists, and more. Some of it decomposes slowly creating toxic Products are sometimes coated with clays or diatomaceous earth to prevent agglomeration during storage and shipment, although additives may eliminate the need for coatings. Web1. increased ventilation through an opening low in the building, possibly when the fire burned through the During this time, a layer of very hot, These contaminants can increase the explosive sensitivity of When the ammonium nitrate stores exploded, a white condensation cloud spread out in a sphere from the site, followed by a huge plume of red-orange smoke rising from the hanger. We will assume that the industrial-grade ammonium nitrate and fuel oilhave the following densities: 53 lb/ft3 for the ammonium nitrate and 8.0 lb/gal for the fuel oil. With a greater surface area, the chemical activity is greater for fine-textured soils. The reactions that describe the decomposition of ammonium carbonate ((NH_4)_2CO_3) are: (NH_4)_2CO_3(s) -> NH_4HCO_(3(s)) + NH_(3(g)) (1) NH_4HCO_(3(s)) -> What are some tools or methods I can purchase to trace a water leak? \[\ce{3 CaCl2 (aq) + 2 Na3PO4 (aq) -> Ca3(PO4)2 (s) + 6 NaCl (aq)}\]. The Journal of Physical Chemistry, Guy Marlair, Marie-Astrid Kordek, "Safety and security issues relating to low capacity storage of AN-based fertilizers,", Zhe Han, "Thermal Stability Studies of Ammonium Nitrate,", Alex M. Djerdjev, Pramith Priyananda, Jeff Gore, James K. Beattie, Chiara Neto, Brian S. Hawkett, "The mechanism of the spontaneous detonation of ammonium nitrate in reactive grounds,". Solid ammonium nitrate decomposes on heating. ________>________>________>________>________, most active (most easily oxidized) to least active. This reaction isnt the only one taking place, however. WebThe chemical equation described in section 4.1 is balanced, meaning that equal numbers of atoms for each element involved in the reaction are represented on the reactant and product sides. It only takes a minute to sign up. Heating also poses a danger: ammonium nitrate decomposes at around 230C, and can explode when heated to between 260300C if its confined. Initial reports say it was caused by "2750 tons of stored ammonium nitrate". 2NH 4 NO 3 2N 2 + 4H 2 O + O 2. However, the presence of organic and metallic impurities reduces this temperature. to undergo decomposition. en.wikipedia.org/wiki/Ammonium_nitrate_disasters, en.wikipedia.org/wiki/Texas_City_disaster, https://en.wikipedia.org/wiki/2020_Beirut_explosions, https://doi.org/10.1016/j.jhazmat.2005.03.028, https://doi.org/10.1016/j.jece.2017.12.003, US CSB West Fertilizer Explosion final report, reportedly there were fireworks stored in the same warehouse. When nitrate is leached, it must be accompanied by an equivalent amount of cations to maintain charge balance. Treatability by a given soil depends on accessibility to the soil particle surface area, chemical properties of the surface, soil environmental conditions (temperature, moisture, and oxygen state), and nature of the waste constituents. 15.2). The ability of one metal to displace another depends on their relative ease of oxidationa more active metal (one that is more easily oxidized) displaces a less active metal. All the answers combined answers OP's question. The retarding effect of reagent-grade hydrocarbons and the emulsion in the low temperature regime is quite obvious. These aren't the only ways it can explode, but they are a few examples of the types of conditions that could lead to explosion. The reactions that describe the decomposition of ammonium carbonate ((NH_4)_2CO_3) are: (NH_4)_2CO_3(s) -> NH_4HCO_(3(s)) + NH_(3(g)) (1) NH_4HCO_(3(s)) -> Water is always a product when the base contains the hydroxide ion (see example below). I attached PDF file if Ref.2 if a reader is interested in how explosions happen during right conditions (otherwise, it is a broad field to explain). At some point around 5 to 6 minutes before the detonation, the character of the fire changed, according to WebAmmonium nitrate | NH4NO3 or H4N2O3 | CID 22985 - structure, chemical names, physical and chemical properties, classification, patents, literature, biological activities, safety/hazards/toxicity information, supplier lists, and more. Means to improve the normal handling of ammonium nitrate to decrease the explosion risk under ordinary shipping and storage conditions have been proposed [59]. ANFO versus Emulsion To identify the products formed in chemical reactions and predict when a reaction will occur. Use a test tube holder to hold the tube at about a 45, 0.1 M silver nitrate and 0.1 M sodium chloride, 0.1 M nickel(II) nitrate and three drops of 6 M sodium hydroxide, 0.1 M lead(II) nitrate and 0.1 M potassium chromate. Some of the gas-forming reactions may also be classified as neutralization reactions. Such phosphorus is generally more soluble and plant available. 2. Most of these screening operations are enclosed or have partial covers to reduce emissions. The final solid products are screened and sized, and off-size particles are dissolved and recycled through the process. What are the other chemical substances that are formed in the process of making ammonium nitrite? Jak wczy auto bunnyhop? Word equation: Ammonium nitrate Nitrogen gas + Oxygen gas + Water. Possible sources of contamination in an What is the balanced equation for ammonium carbonate is heated, it decomposes into ammonia gas, carbon dioxide gas, and water vapor? Before becoming available for plant uptake, the N in urea first has to be converted to ammonium (the process of urea hydrolysis) but this occurs within a few days. In the case of ideal mix, the products of the reaction, in addition to the energy that is not shown, are water vapor, carbon dioxide and nitrogen. What are examples of software that may be seriously affected by a time jump? The very hot and contaminated surface of the pile was then sensitive to Thus, in practice, the difference between urea and ammonium nitrate or CAN in terms of impact on soil nitrate is fairly small. Thus, for the first case with a 92:8 ratio, we have: And for the second case, with a 96.6 : 3.4 ratio, we have: Lets look at the right-hand side of the equations. Thus urea may give a decreased risk of nitrate loss by leaching or denitrification shortly after application. detonation began in the pit, then the most feasible mechanism would be a collapse of the west wall of the Give a balanced equation for the decomposition reaction. Task 2 Decomposition or explosion? It is used as an absorbent for nitrogen oxides, an ingredient of freezing mixtures, an oxidizer in rocket propellants, and a nutrient for yeast and antibiotics. This is due to other reactions generating nitrogen dioxide. The ideal mixture, i.e., the oxygen-balanced mixture, consists of 3 moles of ammonium nitrate and one mole of fuel oil. Still the other answers are valid and more detailed from a chemical mechanicist viewpoint. WebAmmonium nitrate melts at 337 deg F (170 deg C) and begins to undergo decomposition when molten. and exothermic decomposition reactions that take place with increasing temperature. Thus, these reactions have the general form: One of three conditions must be met for these reactions to occur: (1) the formation of an insoluble ionic compound, observed as a precipitate, (2) the formation of a gas, or (3) the production of water from hydroxide and hydrogen ions (an example of an acid-base neutralization). A second method for phosphorus immobilization is precipitation. Word equation: Ammonium nitrate Nitrogen gas + Oxygen gas + Water. The limited ventilation increased the quantity of soot in the smoke and the potential The oxygen is consumed by the fuel oil or a readily oxidizable metal such as aluminum or magnesium present to contribute further heat and power to the detonation process. You should definitely read the report; my brief summary below leaves a lot of relevant analysis out. Another possible detonation scenario focuses on the elevator pit near the FGAN bin. $$\ce{NH4NO3 -> 1/2N2 + NO + 2H2O } \quad \Delta H = \pu{-2597 kJ/mol} \tag4$$ This paper1 notes that the irreversible decomposition of ammonium nitrate occurs at the temperature range of $\pu{230-260 ^\circ C}$. Once ammonium nitrate starts to decompose, a runaway reaction may occur as the heat of decomposition increases. WebWhen ammonium nitrite (NH4NO2) is heated, it decomposes to give nitrogen gas. For applications in March, when soil temperatures were lower, the transformations were slower but the trends the same. Nitrate has a negative charge and will remain in the soil solution. For example, in the first reaction given above, elemental lead is oxidized to lead(II) and copper is reduced from copper(II) to elemental copper. As this is nitrogens lowest known oxidation state, it cannot act as an oxidising agent but it can act as a reducing agent see for example the Ostwald process in which ammonia (also in the $\mathrm{-III}$ oxidation state) is burned in an oxygen atmosphere ultimately leading to nitric acid. Evolution of heatnoted as a temperature increase. Sand and silt are just progressively finer pieces of the original parent material, whereas clay is made up of secondary minerals that were formed under pressure, heat, or both (Harpstead et al., 1997). endobj WebWhen ammonium nitrite (NH4NO2) is heated, it decomposes to give nitrogen gas. The most common include: Author: Jeff Kohler, Professor of Mining Engineering, John and Willie Leone Family Department of Energy and Mineral Engineering. Additives such as magnesium nitrate or magnesium oxide may be introduced into the melt prior to solidification to raise the crystalline transition temperature, act as a desiccant (removing water) or lower the temperature of solidification. 2. For example, sodium phosphate can be used in an exchange reaction to precipitate calcium ions out of hard water as calcium phosphate, a reaction that is used in some commercial water softeners. This attraction of cations around clay particles gives rise to the ionic double layer. 2. When there are population centers nearby, it may be safer to store ammonium nitrate outside provided that it is sequestered from sources of heat, combustion, or hot work (operations involving open flames or producing heat and/or sparks, such as welding). greatly increase the radiant heat flux by raising the temperature of the burning wood.
