What is a coied unit?

Coker unit is the process of heat cracking in the oil refinery industry, which is used to restore valuable elements, the most important of which is oil coke from the remains of the main refinery processes. The coking process involves feeding heated residual oil or pitching into the bottom of a large, upright container known as a coke drum where thermal cracking occurs. The cracking process causes the oil to be divided into gas and steam that rises at the top of the coke drum, and a stiff coke, which collects inside the drum. As soon as the coke accumulates at a predetermined level, the process stops and the coke mass is cut out of the coied unit using high -pressure water jets. Coks taken from the unit are then sent for further treatment to produce fuel or end products at the anode level.

residual oil and coal tar from atmospheric and vacuum distillation columns in oil rafineriiobsIt alsos several valuable elements, including diesel, gas oils and hydrocarbon gases. One of the most important these elements is porous carbon solid known as oil coke or coke pet. Commercial coke has a very high carbon content and can be used as an effective fuel with low emission or in the case of degrees such as a coke needle, for the production of anodes used in steel, titanium and aluminum melting. These products are extracted from the remnants of refineries in the plant part known as a coied unit, usually one of the last steps in the refinery.

2 This crack process takes place in a large, upright container known as a coke drum. The residual oil or pitch is first heated to approximately 930 ° Fahrenheit (500 ° Celsius) and the Fed to the DNA of the coke drum, where the process of cracking begins. During cracking, gases and evaporated oils on the upper part of the Coker unit for collection, while a solid porous coke is built to form a mass inside the drum.

Once sufficient accumulation of Kok is present in the drumSU, feed is cut off and the process stops. When the coke in the drum has cooled sufficiently, the high-pressure water jets are lowered to the top of the drum from the high structures above as De-Coker Derricks. These nozzles cut the coke mass into smaller pieces that fall out of the bottom of the drum for collecting and treatment for the production of fuel or anode products. Coker units generally have two coke drums that allow the process to continue in one drum while the other is recorded. Many larger refineries contain several dual cover units to keep up with production requirements.
