Abstract
The delayed coking process is the most cost-effective and promising technology for processing oil residues and has become most widespread. Oil refineries that include ultrasonic treatment plants can be classified as plants with waste-free oil refining technology. The UZK includes coking and fractionation sections, a furnace block, a coke unloading block, a gas and naphtha separation block, a unit for collecting harmful emissions, a unit for purifying water separated from petroleum coke, a system inside the coke processing unit, a system for compressing and supplying wet gas and others auxiliary systems. The coking section consists of a furnace and 4 reactors operating in parallel to ensure process continuity. The main directions for optimizing the delayed coking process can be considered: changes in the composition of raw materials; improvement of coke chambers of the delayed coking unit; improvement of the fractionating column of the delayed coking unit; modernization of furnaces - the most resource-intensive element of the installation, delayed coking. Ceramic Coating of Furnaces – Applying highly emissive ceramic coatings to furnace coils and linings is an effective energy-saving measure. Allowing to significantly increase the efficiency of furnaces by increasing the thermal load of the radiant section of the furnace, and as a result, reduce fuel consumption.
