Coke formation can be a problem in various refining processes such as cracking, hydrotreating, and others. Coking inhibitors (anticoking additives) are effective in reducing coke formation in refining processes. Coke formation contributes to pressure increase in the reaction mass, as a result of which fuel consumption increases to maintain the temperature regime in the reactor, as well as reduces the working area of the inner surfaces of pipes and there is a decrease in furnace productivity. The use of coking inhibitors helps to improve process efficiency and extend equipment life. The use of coke formation inhibitors helps to improve process efficiency and extend the life of the equipment, thus increasing the overhaul time of the plant and allowing the process to be run in a more severe mode in order to increase feedstock conversion and reduce the viscosity of the final product.
Our Company has extensive experience and a significant portfolio of solutions for this problem using different types of inhibitors, such as Phosphorus-based coking inhibitor. The principle of action consists in passivation of active coking centers on the furnace coil wall.
