■ Product Overview

Catalytic cracking slurry is one of the important products of catalytic cracking units, but it contains a large amount of catalyst fines, heavy aromatic hydrocarbons, resin, asphaltene and other impurities. The presence of these impurities not only affects the quality and subsequent processing and utilization of the slurry, but also causes equipment wear, blockage and other problems. This catalytic cracking slurry settling agent is designed specifically to solve these problems. Through specific chemical reactions, it can quickly and efficiently promote the settling and separation of solid particles and impurities in the slurry, thereby significantly improving the quality of the slurry and ensuring the stable operation of production equipment.

■ Product Features

Efficient settlement: Has strong flocculation and settling ability for catalyst fine powder and other impurities in oil slurry, can achieve solid-liquid separation in a short period of time, high settling efficiency, and can effectively reduce the solid content in oil slurry.

Adaptable: Suitable for the slurry produced by different types of catalytic cracking units, whether it is a slurry made from paraffin based crude oil, cyclohexane based crude oil, or intermediate based crude oil as raw materials, it can achieve good settling effect.

Easy to operate: The usage method is simple. Simply add the settling agent to the oil slurry according to the specified ratio, and mix it appropriately to achieve the settling process without the need for complex equipment and operating procedures.

economical and environmentally friendly: The product has low usage and cost, effectively improving the quality of the slurry without causing environmental pollution, meeting the requirements of green production.

■ Mechanism of action

This settling agent is mainly composed of various surfactants, coagulants, and additives. Its working principle is based on the following aspects:

Surface activity effect: Surfactants in settling agents can reduce the interfacial tension between solid particles and liquids in oil slurry, making it easier for solid particles to disperse in the slurry. At the same time, they can change the surface properties of solid particles, making them more prone to aggregation.

Flocculation effect: The flocculant molecule contains multiple active groups that can adsorb onto the active sites on the surface of solid particles. Through bridging and sweeping, dispersed solid particles are aggregated to form larger flocs, thereby accelerating the settling process.

Synergistic effect: The addition of additives can adjust the acidity and ionic strength of the oil slurry, optimize the working environment of each component of the settling agent, enhance the synergistic effect of surfactants and flocculants, and further improve the settling effect.
