Purified Terephthalic Acid (PTA) is a cornerstone of the global polyester industry, serving as a primary feedstock for PET production, used in everything from bottles to textiles. The manufacturing of high-quality PTA involves several critical steps, one of the most important being the effective removal of moisture. Water contamination in PTA can lead to polymerization issues, affecting the final product’s characteristics and performance. This is where advanced drying agents, particularly activated alumina, play a crucial role. NINGBO INNO PHARMCHEM CO.,LTD. is at the forefront of providing solutions that optimize PTA production through superior activated alumina technology.

The production of PTA typically involves oxidation of p-xylene, followed by purification stages. Throughout these stages, controlling moisture content is vital. Activated alumina, with its exceptional porosity and high surface area, acts as a powerful desiccant, efficiently adsorbing residual water molecules that can impede the subsequent purification and crystallization processes. The physical properties of activated alumina, such as its high crush strength and resistance to thermal degradation, make it an ideal candidate for the demanding environments often found in chemical plants.

Our activated alumina for PTA production is engineered to deliver consistent and reliable performance. We understand that in the fast-paced world of chemical manufacturing, stability and predictability are key. Therefore, our activated alumina products are designed for excellent cyclic stability, meaning they can undergo numerous drying and regeneration cycles without significant loss of adsorption capacity. This regenerability is not only cost-effective but also contributes to more sustainable manufacturing practices by reducing waste.

The specific application of activated alumina in PTA drying involves passing the product stream through beds packed with this adsorbent. As the stream flows through, the activated alumina selectively adsorbs moisture, yielding a purer, drier PTA intermediate. The choice of activated alumina grade and particle size is often tailored to the specific process conditions, ensuring optimal contact time and minimizing pressure drop across the drying unit. NINGBO INNO PHARMCHEM CO.,LTD. works closely with its clients to recommend the most suitable activated alumina specifications for their PTA drying needs.
