Petroleum coke (or pet coke) is a carbonaceous solid obtained from petroleum refining. It is often used as a fuel because it burns hotter than coal and with less smoke, but it has been linked to health problems and environmental damage.
Petcock is classified into two types, high volatility and low volatility. The first contains more than 10% volatile matter. The second has less than 10%. High-volatility coke is used in blast furnaces to produce steel, while low-volatility types are used in power plants as additives to coal or natural gas to generate electricity.
Consumption of petroleum coke:
Petroleum coke is a byproduct of the oil refining process. It consists of carbon and other impurities and is used as a source of industrial fuel. Coke can be converted into various products, such as:
Global consumption of coke is estimated at 10 million tons per year, with China being one of the largest consumers with 3 million tons per year.
Benefits of petroleum coke:
Petroleum coke is a by-product of the crude oil refining process and can be used in many ways. Petroleum coke has many advantages that make it an attractive option for companies looking to reduce their carbon footprint and reduce costs.
Affordability:Coke is one of the most affordable fuels on the market today, making it an ideal choice for companies with limited budgets.
Availability:Coke is produced in large quantities by refineries around the world. بنابراین، منابع زیادی وجود دارد که میتوانید بدون نگرانی در مورد تمام شدن آن در هر زمان یا مکان معین، منابع خود را از آنها خریداری کنید.
adaptation:The versatility associated with this type of fuel makes using petroleum coke an easy decision, as you can use it as an industrial heating source (such as furnaces) or as an energy source when burning waste materials such as rubber or Use plastic.
Petroleum coke in the electricity industry:
If you are a power plant operator, you may be wondering what pet coke can do for your facility. Here are some of the most common uses of coke in the electrical industry:
Production – Coke is burned as fuel to generate electricity. It’s cheaper than coal, making it an attractive option for companies looking to cut costs.
Efficiency – When used as fuel in coal-fired power plants, petroleum coke can improve efficiency by up to 25%. This means less wasted heat and less emissions – both good things!
Petroleum coke in the cement industry:
Petcoke is a byproduct of the oil refining process. It is often used as a substitute for coal in cement production because it is cheaper and cleaner than coal. However, there are concerns about its environmental impact on air quality and climate change.
Petroleum coke in the steel industry:
Coke is a byproduct of the oil refining process. It has many uses, including use in steel production. The affordability of petroleum coke makes it an attractive option for steel producers as well as other industries that generate large amounts of heat or electricity. However, environmental concerns have been raised about its use, as it contains high levels of sulfur and heavy metals such as nickel, vanadium and cobalt.
The process used to produce petroleum coke involves heating bituminous coal (a type of low-grade coal) until its volatile compounds are released into the air as gases that can be used in other processes such as making synthetic natural gas (SNG). ) to be collected. This leaves a solid called “petcoke” that is mostly carbon but contains some hydrogen sulfide along with small amounts of nitrogen oxides and other pollutants such as mercury vapor.
Health and safety concerns
Exposure to disease
Environmental effects of petroleum coke
air pollution :
Coke is a very toxic substance that can cause damage to the environment if released into the air. It contains high levels of carbon monoxide, sulfur dioxide, nitrogen oxides, and particulate matter known to cause respiratory and other health problems in humans.
When coke is discharged into waters such as rivers or oceans, it causes severe water pollution due to the high content of heavy metals such as mercury (Hg), lead (Pb), cadmium (Cd), etc. They are toxic to aquatic species such as fish and shellfish. They also accumulate in the bottom sediments of these bodies, causing long-term effects on marine ecosystems as well as human health through the consumption of seafood from polluted waters. Uranium-238; Thorium-232; Radium-226 and Polonium-210, which may be released into the soil during storage or transport and leach into the groundwater surface.
Which countries consume the most petroleum coke?
The highest consumption of petroleum coke in 2021 was reported by China, India, America, Brazil and Japan, respectively. But it should be noted that the consumption of petroleum coke by countries may change over time and depend on factors such as changes in steel production, aluminum production, and the needs of different industries.
Petroleum coke and compounds
Pet coke is a solid, carbonaceous substance obtained from the destructive distillation of crude oil. It is classified into two types of high volatility and low volatility.
High volatility coke (HVPC) has a high content of volatile organic compounds (VOCs). Low Volatility Coke (LVPC) contains little or no VOCs.
Petroleum coke is a byproduct of oil refining and is used in various industries. It is estimated that the global consumption of petroleum coke will be about 10 million tons per year by 2020. China is one of the biggest consumers of the substance – it uses about 70% of its production domestically and exports most of the rest.
Coke briquettes are made from coal or pet coke, which gives them high thermal conductivity properties that make them useful in furnaces and boilers. Coke ovens use the heat produced from burning coal or oil shale to cook carbon from ore deposits so that they can be converted into metals such as iron or aluminum. These processes also produce large amounts of waste material called coke (similar in composition to petroleum coke). Finally, firebricks are made from baked clay mixed with mineral additives such as silica sand. These materials must withstand extremely high temperatures without melting over time due to their use inside furnaces in steel mills or other industrial facilities where intense heat destroys ordinary bricks in minutes.
