■ Product Overview

This catalytic cracking slurry scale inhibitor is a high-performance product developed specifically for the slurry system of catalytic cracking units in refineries. During the catalytic cracking process, the oil slurry is rich in complex components such as aromatic hydrocarbons, gum, and asphaltene, which can easily form stubborn scale layers on the surfaces of equipment and pipelines, affecting the normal operation of the equipment. This scale inhibitor, through its unique chemical mechanism, can effectively inhibit the aggregation, crystallization, and deposition of scaling substances in the oil slurry, ensuring the smooth operation of the oil slurry system, guaranteeing the stable and efficient operation of the catalytic cracking unit, reducing equipment maintenance costs, and improving the overall efficiency of refining production.

■ Product Features

Efficient scale inhibition: With innovative formulas, it exhibits excellent inhibitory ability against common scale types in catalytic cracking slurry, such as carbonaceous scale formed by aromatic hydrocarbon condensation, organic scale formed by the aggregation of asphaltene, and inorganic scale generated by the precipitation of inorganic salts. It can significantly reduce the scaling rate of the slurry system, with a scale inhibition rate of over 90%, greatly extending the cleaning cycle of the equipment.

Excellent dispersibilityHas excellent dispersibility, able to evenly disperse the small scale particles that have already formed in the oil slurry, preventing them from further aggregating and adhering to the surface of the equipment. This not only helps maintain the fluidity of the slurry, but also reduces system failures caused by local blockages, ensuring smooth transportation of the slurry within the device.

Adaptable: Fully considering the complex operating conditions of the slurry system in the catalytic cracking unit, it can stably exert its scale inhibition effect under high temperature and high pressure reaction conditions, as well as in the face of slurry produced by different properties of raw oil. It has good compatibility with other components in the slurry and materials inside the device, and will not interfere with the normal production process.

Corrosion inhibition synergistic effect: At the same time as scale inhibition, it has a certain corrosion inhibition effect on the metal equipment of the oil slurry system. It can form a dense protective film on the metal surface, effectively slowing down the corrosion of equipment caused by corrosive substances (such as sulfides, nitrides, etc.) in the oil slurry, extending the service life of equipment, and reducing the frequency of equipment replacement.

Safety and Environmental Protection: Select environmentally friendly raw materials that comply with relevant safety and environmental standards. During use, it ensures the safety of operators and poses minimal environmental hazards. After use, there will be no residual harmful substances in the device or environment, making it easy to handle and in line with the development concept of green refining.

■ Scope of application

This catalytic cracking slurry scale inhibitor is suitable for the slurry systems of various refinery catalytic cracking units, specifically covering the following key parts:

Oil slurry heat exchanger: Equipment used for heat exchange between slurry oil and other media in catalytic cracking units. During the heat exchange process, the temperature of the oil slurry changes, and the scaling substances in it are prone to deposit on the surface of the heat exchanger tube bundle, which affects the heat transfer efficiency. The use of this scale inhibitor can effectively inhibit the formation of scale layers, maintain the efficient operation of the heat exchanger, and ensure the reasonable transfer and recovery of heat.

Bottom of fractionation tower and oil slurry circulation pipeline: The bottom of the fractionation tower is the convergence point of the oil slurry and also the area with a high risk of scaling. When the slurry flows in the circulation pipeline, it is prone to scaling on the pipe wall due to factors such as flow rate and temperature. The addition of scale inhibitors can prevent scaling at the bottom of the tower and in pipelines, ensure the normal circulation of oil slurry, and maintain the stable operation of the fractionation tower.

Slurry pump: The key equipment responsible for transporting slurry oil. Scaling may lead to impeller wear, reduced pump efficiency, and even pump failure. This scale inhibitor can reduce the erosion of scale in the slurry on the pump, extend the service life of the slurry pump, and ensure the stability and reliability of slurry transportation.
