A new generation of environmental friendly flairers:
Today, mankind is not just about expanding industries, and industry is not just about production and profitability. With the rapid advancement of science and technology and its impact on the inclusion of industry in life and the environment, new demands are pushing industries to have the best technology of the day, which can no longer be interpreted as the most profitable. The path of industries must preserve the environment, have the lowest production costs, and have the most productivity. The attitude of today’s societies is to preserve and protect environmental factors, and this is reflected in agreements such as the Kyoto Treaty that raise the concern of global forums about the changes and pollution caused by the industrialization of today’s world.
Sometimes, some organizations take steps to increase grants and, without taking into account the economic benefits, provide grants for projects aimed at protecting the environment and reducing pollution.
So in an increasingly industrialized world, environmental issues will be more important than ever.
These days, there is such a widespread view in the Iranian oil, gas and petrochemical industry as the country’s largest industry, and that is why pollution has come under the scrutiny of environmentalists and environmentalists.
The solution to this problem, in addition to the importance of human resources and industrial safety, depends on the performance of other health and environmental organizations.
Considering this issue in the petroleum industry, the issue of flaring will be one of the most important in the field of the environment. Large volumes, often black smoke, also go to the sky. The number of burners in industrial areas such as Assaluyeh makes this even more worrying.
Common burners used in the industry, Elevated Flare, have three types of emissions. Specifically, their maximum emission levels can be attributed to non-combustion greenhouse gases, although combustion efficiency exceeds 95% in the design of such flasks, but due to calculations being far from the actual conditions of the industrial environment. And designing based on public data cannot be described in terms of performance as accurate and accurate calculations. On the other hand, as these flares burn above the stack, environmental factors, such as wind, affect the amount of oxygen delivered to the gases and sometimes reduce the combustion efficiency by up to 70%. . This is especially true in the production of carbon monoxide gas. In many cases there is no need to prove the low combustion efficiency of these flares because this can be clearly seen from the black smoke generated by the high flare flames. If the combustion is complete in Elevated Flare only carbon dioxide and water vapor should be present. Sulfur oxide is produced as combustion products. But in practice the combustion of gases at the tip of the flyer is not possible and hence other gases such as benzene, mercury, nitrogen oxides, carbon monoxide, arsenic, carbon disulfide, chromium, methane, sulfur, carbonyl toluene, acidic hydrocarbons, and hydrocarbons. On the other hand, given the fact that the flame is at the highest point of the flare and sometimes it is more than 100 meters high, there is no possibility of analyzing the high flame because of the impossibility of installing any analyzer. Therefore it would not be possible to obtain accurate statistical data on the burning of these types of flies.
Due to their massive flame, these types of flames have high thermal radiations that cause them to move away from the process plant so that in the areas of Assaluyeh, the slopes of the mountains are filled with these flasks, which range from 100 to 250 meters. The main flame as a forbidden area occupies a considerable area of any living use.
The third factor is noise pollution. Injecting water vapor into the flares to prevent smoke from producing a loud noise that reaches 140 dB in the flare tip. This is almost twice the maximum acceptable level (85 dB) in industrial units, which cannot be eliminated due to the structure and design of these flies.
The new generation of flares seeks to eliminate all pollution associated with the traditional generation of gases. Fluors such as ground or chamber flies are an example of this technology.
Ground flares and some of them, called GROUND FLARE, are part of CLOSED FLARE. In this type of flares, which are more like a waste incinerator (BURNRS), the burners are placed at the bottom of the stock, which is why they are named Ground Flare.
These types of burners, with their burners at the bottom of the chimney, provide the ability to combustion in controlled conditions. Therefore, the effect of environmental factors such as wind on the combustion efficiency is minimized. It also makes it possible for a flyer to have a forced draft if the design needs to be oxygenated or aeration with blowers. Under these conditions, the combustion efficiency reaches 99.999% and in the case of incomplete combustion pollution emissions are reduced to a very small extent. On the other hand, what is important for the protection of the environment and those responsible for the environment is the requirements for the measurement and analysis of pollutants, especially given the low flue combustion in ground flames. It is possible for the analyzer to be mounted on the top of the chimney and to obtain very accurate statistical information of the combustion gases.
So full access to how these types of flavors work will be in different environments and industries, and you can’t just rely on the engineering and pre-fabrication documentation. This allows the design of these types of flies to take into account all the prerequisites and environmental considerations so that the designed flies are exactly in line with the environmental conditions of the installation and use.
On the other hand, the packing system of these flares and the possibility of their internal insulation on the one hand and the flame inside the flue and non-exit and observation on the outside of the flue have on the other hand caused the ground flares to have no thermal radiation and In practice, when operating these flares, the body of the flare is placed at or slightly above ambient temperature such that it is possible to handle the flare body under these conditions. In fact, one of the major disadvantages of flair is somehow eliminated and the use of this method has eliminated the banned thermal range. This advantage creates two types of capabilities in industrial units. First, by eliminating the thermal radiation, the industrial unit’s safety range is increased and the thermal pollution caused by the flares is eliminated. This allows access to a significant portion of industrial land, which is nowadays very important in terms of space constraints in some parts of the country. Second, these flares will be installed right next to the process plant, and there is no need to build flaring lines and remove the flare from the process unit. This also reduces construction costs in the overall Flair package.
Along with these, of course, it is also important to minimize the noise generated by ground flares. Due to the increase in diameter of these flares, the burners are designed to be located below the chimney of the flutes producing less than 85 dB, within the range of industrial units. Therefore, noise pollution in industrial units is standard and acceptable for employees.
This generation of florets, which have been used in European industry for many years and is also endorsed by environmental organizations in these countries, could also be a good substitute for the current floras in the Iranian Nef industry. However, the growing trend and very good policy at the macro level of the petroleum industry towards reducing gaseous fuels is also a cure for the event prior to its treatment. Although it is not possible to completely remove the fluorine now, with new methods and technologies to recycle it it is possible to minimize the combustion gases, which can be the final complement to these designs. And minimize environmental waste.
The burning of 28 million cubic meters of oil per day comprises a huge amount of the country’s resources, which in addition to the proper management of these resources can prevent environmental damage and select the best way to burn these gases.
