Flue gas cleaning is a crucial process in the industry that aims to remove pollutants from the gases generated during the combustion process. The procedure is essential to protecting the environment from toxic emissions that may result in a number of health issues. Since its start, flue gas cleaning technology has advanced significantly, and industry innovation has resulted in more effective and efficient means of removing contaminants.
The first flue gas cleaning system was constructed in a lead chamber process facility in Britain at the beginning of the 20th century, beginning the history of flue gas cleaning technology. A wet scrubber was primarily employed in the straightforward system to remove sulfur dioxide from the flue gases. The technology advanced in the 1950s, and more advanced techniques such as electrostatic precipitators and fabric filters were introduced to the industry.

What are the most common technologies used for flue gas cleaning in Crude Oil Refinery industry?
The control of flue gas emissions is one of the major difficulties in the refining of crude oil. Particulate matter, sulfur dioxide, and nitrogen oxides are among the contaminants found in flue gases, which are created when crude oil is burned. It is vital to develop efficient flue gas cleaning systems since these pollutants can have detrimental consequences on both human health and the environment.
What are the most widely utilized technologies in the crude oil refinery business for cleaning flue gases? Let’s look more closely.
Wet Scrubbers
A common and efficient device for reducing flue gas pollution is wet scrubbers. These devices filter out impurities from the gas stream using a liquid, usually water. Particulate matter, sulfur dioxide, and other pollutants may be efficiently removed using wet scrubbers. In order to capture the impurities, they spray a liquid into the gas stream, generating a cloud of droplets. The droplets are subsequently removed from the gas by a mist eliminator, which ultimately permits the clean gas to leave the system.
Electrostatic Precipitators (ESP)
Pollutants in flue gases can also be controlled using electrostatic precipitators (ESP). To clean the gas stream of particles and contaminants, these devices employ an electric field. The gadget creates an electric field that charges the gas as it moves through it, which in turn charges the particles. After being drawn to a collection surface, the charged particles are finally expunged from the gas stream. Wet scrubbers can be used in conjunction with ESPs, which are particularly good at catching tiny particulate matter, to provide complete pollution management.
Selective Catalytic Reduction (SCR)
Nitrogen oxides are taken out of flue gases using a process called selective catalytic reduction (SCR). The procedure involves putting the gas through a catalyst bed, which encourages the chemical reaction that turns harmful nitrogen oxides and ammonia vapor into safe nitrogen and water vapor. A catalyst, such as platinum or palladium, is often deposited on a ceramic substance that serves as the catalytic bed. The SCR procedure is widely employed in power plants and other industrial facilities because it is very successful in reducing nitrogen oxide emissions.
Flue Gas Desulfurization (FGD)
Sulfur dioxide is taken out of flue gases using the flue gas desulfurization (FGD) technique. The gas and a cleaning substance, usually limestone, engage in a chemical process that results in the production of calcium sulfate. The cleansed gas from this waste can be safely discharged into the atmosphere. FGD systems come in a variety of forms, such as wet scrubbers, dry scrubbers, and spray dryers. The most popular FGD technology is a wet scrubber because of how well it removes pollutants like sulfur dioxide.
The crude oil refinery industry employs a range of technologies to manage flue gas emissions. Wet scrubbers, ESPs, SCR, and FGD are some of the most commonly used technologies for flue gas cleaning. Each technology has its advantages and disadvantages, and the selection of the appropriate technology depends on a variety of factors such as the type and concentration of pollutants present in the flue gas stream. It is essential to use effective and efficient flue gas cleaning technologies to protect human health and the environment.
Introduction to the latest and most promising technologies in flue gas cleaning
There is a growing need for more innovative solutions to meet increasingly strict environmental regulations.This has led to the development of emerging technologies that show great promise in flue gas cleaning.
Use of activated carbon
One such technology is the use of activated carbon. Activated carbon can adsorb and remove pollutants such as mercury, dioxins, and furans from flue gases. The technology works by injecting activated carbon into the gas stream, where it adsorbs the pollutants onto its surface. The carbon is then removed from the gas stream, and the pollutants are trapped within the carbon. This technology has several benefits, including high removal efficiencies, low operating costs, and the ability to be used in combination with other flue gas cleaning technologies.
Use of plasma reactors
Plasma reactor technology is another cutting-edge innovation. In plasma reactors, a plasma field is produced in the gas stream using an electric discharge. Free radicals and ions produced by the plasma field can interact with contaminants to transform them into harmless molecules. In particular, volatile organic compounds (VOCs) and other dangerous air pollutants may be effectively eliminated using plasma reactors. High removal efficiency, minimal operating costs, and the potential to be applied in a variety of sectors are just a few advantages of this technology.
A German cement mill is one location where plasma reactors have been successfully used. The factory reduces emissions by 90% by removing VOCs from its flue gas using a plasma reactor. regulations. The technology has proven to be cost-effective and has helped the plant meet stringent environmental regulations.
Ozone oxidation, moist electrostatic precipitation, and biological flue gas cleaning are other cutting-edge flue gas cleaning techniques. These methods can be used with other technologies to accomplish complete pollution management, and each one has particular advantages.
These new flue gas cleaning methods have very broad potential in the future. Industries will need to invest in cutting-edge technology to decrease their emissions as environmental restrictions get stricter. High removal efficiency, low operating costs, and superior environmental performance might all be provided by emerging technology. These technologies may in the future set a new benchmark for flue gas cleaning with further research and development.
Although there have been significant advancements in flue gas cleaning technologies, a number of issues still need to be resolved before new solutions can be widely adopted. The cost of incorporating this technology is one of the biggest barriers since it may be out of reach for many firms. The need for affordable and efficient flue gas cleaning solutions will, however, only increase as more companies begin to see the benefits of reducing emissions.
Despite these difficulties, there are several chances for innovation and teamwork in the flue gas cleaning sector. Companies that can keep on the cutting edge of these advancements will be well-positioned to prosper as new technologies are always being created. Additionally, there are chances for cooperation between various businesses in the sector as well as between businesses and governments.
