In the field of petrochemicals, aromatic extraction is a crucial process that aims to separate and extract important aromatic products such as benzene, toluene, and xylene from hydrocarbon mixtures. However, in the process of aromatic extraction, foam problems often cause many troubles to production, and the emergence of aromatic extraction defoamers effectively resolves these problems and becomes a key additive to ensure the smooth production of aromatics.

The presence of foam brings a series of serious hazards to the aromatic extraction process. In terms of production efficiency, foam will occupy the effective space in the extraction equipment, resulting in a reduction in the actual mass transfer area. This means that the separation efficiency between aromatics and non-aromatics is reduced, and it takes longer time and more energy to achieve the expected separation effect, thereby increasing production costs and reducing production efficiency.

Aromatic extraction defoamers mainly work in the following ways. First, the active ingredients in the defoamer have a low surface tension and can quickly migrate to the foam surface to form a new layer of low surface tension film on the foam surface. This film will destroy the original surface tension balance of the foam, making the liquid film on the foam surface thinner and eventually rupture, thereby achieving the purpose of defoaming.

Aromatic extraction defoamers play an indispensable role in the production process of aromatics. It can not only effectively solve the foam problem, improve production efficiency and product quality, but also protect equipment and reduce production costs. With the continuous development of the petrochemical industry and the increasing requirements for the quality of aromatic products, aromatic extraction defoamers will also continue to innovate and improve to better meet production needs and provide a solid guarantee for the stable development of the aromatics industry.
