Description

1 TARIFF IN GOLD PURIFICATION REFINERIES AND REMATTING FACILITIES A device that prevents the toxic gas produced from being released into the atmosphere. SYSTEM AND A METHOD RELATED TO THIS SYSTEM 5 Technological Field: This invention addresses the toxic substances produced in gold refining refineries and refining plants. It is related to a system that prevents the release of gas into the atmosphere. 10 The invention has implications for gold refining processes, particularly aqua regia and the purification of gold. It is a system that filters the gases released during the decomposition stages. State of the Art: 15 In refining processes, precious metals such as gold, platinum, and palladium are extracted from aqua regia. It is purified with a solution called aqua regia, especially. During the purification process, a wide variety of toxic and acidic gases are released. Aqua regia is used with metals like gold and platinum, which are minimally or unaffected by acids. It is a highly reactive acid solution. Concentrated Nitric Acid (HNO3 - a mixture of nitric acid (nitric acid) and concentrated hydrochloric acid (HCl-muriatic acid) (formed by mixing acid and nitric acid in a 3:1 ratio) a highly corrosive substance, It is a fuming, yellow-red solution. Nitric acid removes the metal in very small amounts. It oxidizes and converts into ions; hydrochloric acid, in turn, reacts with chloride ions in the environment. It complexes the metal ions and continuously attracts the metal into the solution. This process... During this process, Nitrogen Oxides (NO, NO2), Chlorine Gas (Cl2), Nitrosyl Chloride (NOCl), Gases such as hydrogen chloride (HCl), sulfur dioxide (SO2), and arsine (AsH3) are released. It is coming out. 30 2 Nitrogen oxides are released when nitric acid (HNO3) decomposes in aqua regia. It is the most prominent gas. NO2 (Nitrogen Dioxide) is a reddish-brown gas with a pungent odor. And it is a highly toxic gas. NO (Nitrogen Monoxide) is colorless but mixes with air. It converts to NO2 upon contact. Causes pulmonary edema, respiratory tract burns, and serious injuries. It causes poisoning. Chlorine gas (Cl2), hydrochloric acid and nitric acid 5 It appears as a byproduct of the reaction between them. In yellow-green tones, It is a suffocating and highly irritating gas. It can irritate mucous membranes, eyes, and It can cause serious damage to the respiratory system. Nitrosyl Chloride (NOCl), synthesized during the formation of aqua regia and released in the gas phase It is an orange-yellow compound. It tends to decompose in the air into chlorine and nitrogen oxides. It shows that hydrogen chloride (HCl) in the solution is heated during the reaction. Hydrochloric acid can evaporate and mix with the air. It is a sharp and irritating acid. It produces smoke. Depending on the type of other metals in the refined gold. Different gas emissions can also be observed. Gases released during refining processes pose a vital risk, especially in confined spaces. These gases pose a danger. They are harmful to human health as well as to the environment. This is extremely dangerous. Nitrogen oxides and chlorine gas mix with moisture in the atmosphere. They combine to form nitric acid and hydrochloric acid. This is what causes acid rain. They descend to the earth and cause damage to vegetation, water resources, and buildings. Nitrogen dioxide contributes to ground-level ozone formation and hazy air. This leads to the formation of these conditions and a decrease in overall air quality. For this reason, toxic substances are produced in gold refining refineries and refining plants. that allows the gas to be collected from its source before it spreads into the atmosphere. systems are used. Simplified wet filters are among these systems, 25 of which are used. Some of them. Patent application number US5637282 describes "Nitrogen with Alkaline Peroxide Solution". An invention titled "Oxide Washing" is described. This system is used for gold purification and This is an example of aqueous filters used in ramat plants. This system removes toxic nitrous oxide 30. To prevent the release of (NOx) gases into the atmosphere, the gas emission should be treated with alkaline The invention describes the passage of a gas through an aqueous scrubber containing a solution. 3 the flow is maintained by passing the liquid through an alkaline solution whose pH is kept between 8 and 14. Its dissolution in the pool and the corrosive effect of the gas are broken down, rendering it completely harmless. It ensures that it is brought into this state. In patent application number CA1165099, "Derivation of Nitrogen Oxides from Gases" "Removal" is described. This patent covers photochemical smoke and acid. Nitrous oxide (NOx) gases, one of the main causes of rain. a gas cleaning (wet) system developed to prevent its release into the atmosphere The invention describes the scrubbing method. It involves two methods for the purging of toxic gases. It offers a multi-stage wet filter system. In the first stage, the gas is exposed to acid, 10 It is then reacted by being passed directly through a caustic alkaline pool. This invention analyzes the acidic, colored, and smoky gas produced during gold refining. This method, ideal for suppression, maximizes the rate at which the gas dissolves in the liquid. It is designed to do so. Patent application number EP1866060 describes a “Wet Type for Exhaust Gases”. The patent describes a "washer" that removes harmful exhaust fumes released from industrial facilities. a wet-type gas scrubber designed to clean gases It describes the system. The invention relates to acids found in industrial exhaust gases. the components and particles are sprayed with an alkaline solution and the gas is mixed with this aqueous 20 It neutralizes the substance by forcing it to pass through the layer. This The patent works by having acidic gas react with alkaline liquid, causing mud to settle at the bottom. conversion and refining processes of molten particles together with gas It is based on the principle of preventing it from escaping into the atmosphere. In this system, the gas The moisture inside and the water vapor from the liquid spray are exactly 25 Because the problem could not be solved, extra dehumidification was necessary before the gas was introduced into the system. Equipment is needed. Patent application number WO1994012429, “NOx / SOx from gases The "Process of Removing Oxides" is described. This invention, chemical 30 from industrial sources such as operations, production facilities and power plants nitrogen oxides (NOx) and sulfur oxides (SOx) in the emitted waste gases 4 It uses chloric acid as an oxidizing agent to remove waste. Nitrogen and sulfur oxides in the gases first pass through an oxidizing pool, and then... dilute NaOH (sodium hydroxide) or a carbonate-based alkaline absorbent The absorbent is washed by passing it through the liquid. In patent application number US20030177904, "Using a Bubble Generator" The "Exhaust Gas Cleaning Process" is described. This invention aims to clean polluted industrial exhaust gases. by injecting gases into a reaction fluid pool from the bottom, micro- It is made to rise to the surface in the form of bubbles. The contact surface between the liquid and the gas. By maximizing the area, this method removes harmful components from the liquid in 10 seconds. It dissolves completely as it rises and only from the top of the system does it reach the atmosphere. Purified air is released. In the current system, systems that operate on the principle of dissolving waste gas in liquid are used. The following methods and approaches can also be used as alternatives or supplementary options: 15 It is used. Dry absorption is one of them. Dry absorption (active (carbon and chemical filters), where aqueous systems cannot be installed or additional protection is required. They are used when required. The gases are specially impregnated with active ingredients. It is passed through carbon, zeolite, or limestone beds. Closed-loop refining. systems, chemical reduction, anti-fog balls or chemicals these 20 These are some of the systems. In conclusion, this stems from the shortcomings of the systems mentioned above. eliminating inefficiencies and creating alternatives to other efficient systems. A new, low-cost and more efficient technology is needed. 25 Description of the invention: This invention addresses the toxic substances produced in gold refining refineries and refining plants. It is a system that prevents the release of gas into the atmosphere; its feature is that it provides the solution in the fastest 30 minutes. and for businesses that want to reach their goals in the most efficient way during the refining process It is the most balanced method for solving the emission problem. It does this within a closed system. This is ensured by working venturi tubes. The invention addresses the problem of expensive filter cartridges or enclosed systems in dry absorption systems. The circuit systems require complex automation and vacuum infrastructure. 5 It is not audible. Made from highly acid-resistant polypropylene (PP) or PVC material. It is economical because it is designed so that the operator can easily monitor the liquid inside the tank. It can carry out evacuation / supply without shutting down the system. The invention describes chemicals (typically Sodium 10) used to neutralize the gas. Hydroxide (caustic soda) is readily available on the market and can be produced using activated carbon or special chemicals. These are materials that are much cheaper than reducing agents. Cheap Consumables Its use reduces operating costs. The most significant advantage of the invention is its low investment and operating costs. 15 Gold refining does not produce a single type of gas; NOx and HCl (hydrochloric acid) are also produced during the process. (chlorine vapor) and sometimes Cl2 (chlorine gas) are found together. The invention describes how these different gases can be combined. It traps all of it in the liquid in a single pass. Thus, what is released into the atmosphere... The final exhaust gas is colorless, smokeless, and completely free of acidic gas content. It becomes purified. 20 The invention explains why gases cool instantly when passing through liquids. This is due to the heat of the gas. It eliminates the risk of fire that may occur. Also during gold refining... Any micro-sparks that may occur are extinguished within the liquid, acting as a spark arrestor. does. 25 Explaining the Figures: The invention will be described by reference to the attached figures, so that the invention Its features will be understood and appreciated more clearly, but the purpose of this is 30 The aim is not to limit the invention to these specific regulations.

Detailed Description of the Invention: 30 8 Especially during purification with aqua regia, a wide variety of toxic and acidic gases are released. These gases are released. These gases should be cleaned and released into nature in a harmless way. Gases present in the environment are drawn into the first liquid tank (1) via the suction line (E). For this purpose, with the help of the motor (M), the pump water (S) flows into the 1st liquid tank (1) It is transferred into it. The pump water (S) line allows the system to create a vacuum. This is the main contributing factor (Figure-1, Figure-2). Pump water (S) into vacuum tanks (4) located inside liquid tank (1) It is transmitted. Depending on the amount of gas to be treated or the need, it is in liquid form. One or more vacuum tanks (4) can be placed inside the tanks. 10 Vacuum tanks (4) are systems that create a vacuum with pump water (S). In this direction, with the help of the motor (M), the pump water (S) is pumped into the vacuum tanks (4) It is transmitted. Here the collector (4.1) divides the vacuum tank (4). Upper in the section, the liquid chamber (4.2) where the pump water (S) is collected, and below it is the venturi. There is a gas chamber (4.3) where the cylinders (4.4) are located.
