Chemical applications
Coek designs and manufactures reactors 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 reactors and its internals is engineered to meet the specific requirements of your process installation, with a focus on safety, durability, and precision. Oxidation reactors for PTA application are built with diameters close to 10 m.

Reactors Materials
For demanding chemical applications, reactors are often exposed to harsh conditions, such as high chloride concentrations, requiring the use of exotic materials. Coek employs a variety of materials,including titanium, zirconium, and tantalum,to ensure corrosion resistance, durability, and reliable performance across its reactor portfolio.
Titanium
Oxidation reactors
— PTA, BrineCoek has a long reference on fabrication of oxidation reactors in Titanium clad for PTA and Brine applications. PTA reactors are built with diameters close to 10 meter.
Chlor Alkali reactors
— Chlor AlkaliFor Chlor Alkali, reactors are typically fabricated in solid Titanium with diameters up to 5 meter.
Tantalum
Ta Reactors
— Poly CarbonateFor Poly Carbonate applications, reactors are fabricated with Tantalum liner (using a copper innerlayer). There reactors have typically a carbon steel jacket.
Carbon Steel
Oxychlorination reactors
— Vinyl ChlorideFor Vinyl Chloride, Coek was involved in several projects to produce Oxychlorination reactors. Although the material is carbon steel, the design of this reactors with a large amount of internal piping is challenging.
Polypropylene reactors
— PolypropyleneCoek is specialised in the fabrication of Polypropylene reactors. where it is not only involved in the reactor fabrication, but covers the complete reactor section, including the agitator, drive system, mechanicals seals, and instrumentation.
Zirconium
MEG reactors
— Mono ethylene GlycolFor MEG reactors, Johnson Mattheys developped a technology using high pressure Zirconium clad reactors for which Coek has received the approval to fabricate these complex items.
Hastelloy and Zirconium
Acetyl reactors
— Acetic AcidCoek has produced a substantial number of reactors in Hastelloy clad and Zirconium clad for Acetic acid applications for different licensors.
Reactor Applications
From polymers to acetic acid, our reactors are custom-engineered for each chemical process. By selecting the right materials and design, we ensure maximum durability, process safety and performance — even under extreme operating conditions.
PTA
Our reactors for Purified Terephthalic Acid (PTA) are built to withstand high pressure, temperature, and corrosive media. They ensure stable performance in continuous production environments with excellent resistance to halides.
Acetic Acid
Acetic acid processes demand superior material selection and design integrity. Our reactors offer enhanced durability and chemical resistance, ensuring safe and long-term operation in corrosive environments.
Chlor Alkali
Polypropyelene
Since 1990, Coek has been engaged in the fabrication of polypropylene (PP) reactors, with a primary focus on horizontal reactors used for producing homopolymer, copolymer, and impact copolymer grades.
MEG (Monoethylene Glycol)
Coek is involved in the fabrication of high pressure Zirconium clad reactors and heat exchangers for MEG applications.
Brine Purification
Brine purification used during the fabrication of EPOXY resins is a technique which requires equipment using high end oxotic materials like Ti GR17 and Zirconium materials. Coek has fabricated equipment (Columns, reactors and heat exchangers) for the brine treatment technology patented by KVT in Austria.
PEF
Tailor-made for the bio-based polymer industry, our PEF reactors support precise temperature control and corrosion resistance. Ideal for companies scaling up sustainable packaging solutions.
Projects
Reactor projects at Coek showcase expertise in fabricating high-performance equipment for demanding chemical processes. Using advanced materials such as titanium, zirconium, tantalum, and clad constructions, each project delivers corrosion-resistant and durable reactors tailored to specific process conditions.
