The calcined oil coke recycling is a more energy-efficient option to fossil fuels. This process reduces carbon emissions and air pollutants, while lowering manufacturing costs. The recycled product is suitable for many applications, including aluminum smelting. It can also be used to produce steel, reducing the need for natural resources like iron ore. It can also replace coal in cement-kilns. In addition, reusing this material will help to save money on shipping and handling costs. The calcined petrol coke, a byproduct from oil refining with a very high carbon content, is a product of oil refining. It is made by heating crude oils to high temperatures in cokers, which produce a solid residue called petroleum coke or PETCOKE. The coke is then further processed, or calcined, to produce anode grade coke for use in aluminium smelting. This step is crucial in the smelting process of aluminium as it provides the low sulfur and metal content necessary to make anodes.
The recycling of calcined petroleum coke is an important process to improve the environmental impact of the smelting industry and to conserve natural resources. This is achieved using a waste heat recuperation system to capture excess power from the rotary kiln. This energy is converted into steam and used to produce electricity. These systems are mandatory in many rotary ovens.
The amount of water needed to cool down the calcined coal is a key factor in determining how efficient the waste heat recovery system is. It is essential to have a precise measuring system in order to achieve the best results. Ultrasonic liquid flowmeters should be used to monitor the water flow in the cooling pool and heat exchanger in order to determine the temperature and amount of water being used for calcining. The WSM D is the best choice for this application, as it has a wide measuring range, a high degree of repeatability, and enables easy installation.
The toxicity was determined by comparing the growth rate of an algae (Selenastrum capsricornutum), two crustaceans (Thamnocephalus playrurus, and Daphnia Magna), one rotifer species (Brachionus calyciflorus), and one protozoan species (Tetrahymenathermophila). These organisms did not show any toxicity after the contaminated wastewater had been applied to the medium for 24 hour. This result indicates the contaminated waste water can be recycled, without affecting its growth rate or viability. This is an important discovery that can be applied to a variety of industrial processes. The price of calcined petrol coke in Europe stabilised during Q4 2023. This reflects a delicate balance between supply and demand. The market will remain volatile and be influenced by global energy trends, economic indicators and other factors. Moreover, the supply of the material from the Antwerp port will have a major impact on pricing. This is why the market must monitor the impact these variables have on the prices of calcined and other commodities.
