Chemical applications
In chemical processes, columns are often exposed to extreme temperatures and highly aggressive media. Whether used for distillation, absorption, or extraction, they must offer excellent corrosion resistance, structural integrity, and long-term reliability.

Columns materials
Coek designs and manufactures columns using high-grade materials such as titanium, zirconium, or tantalum, or as explosion-clad alternatives with a corrosion-resistant inner layer. This approach ensures optimal performance while maintaining cost-efficiency. Each column is engineered to meet the specific requirements of your process installation, with a focus on safety, durability, and precision.

Column Applications
Columns play a vital role in countless chemical processes, from separation and distillation to absorption and stripping. Coek Engineering offers tailored column solutions for various applications, ensuring process reliability, corrosion resistance and long-term performance in the most demanding conditions.
PTA
Columns for PTA (Purified Terephthalic Acid) production are designed to handle highly corrosive process streams, particularly those involving brine or chloride-rich media. Coek Engineering delivers column solutions with advanced cladding materials to ensure optimal performance and long-term resistance.
Acetic Acid
Acetic acid processes demand columns that can withstand aggressive acidic environments. Coek Engineering provides tailored column solutions with corrosion-resistant materials to guarantee operational safety, reliability, and longevity under harsh conditions.
Brine Purification
Brine purification is a critical step in the production of high-purity chlorine, caustic
soda, and other derivatives.
Poly Carbonate
Poly carbonate (PC) is an advanced copolymer resins with outstanding transparency, impact resistance and heat resistance.
Projects
Coek has built a strong track record in the fabrication of complex process columns. With extensive expertise in working with exotic materials and clad constructions, the company delivers columns for demanding applications such as acetic acid processing.
