Your challenge – our answer
Petrochemical processes demand the highest levels of process reliability, strict compliance with standards and maximum efficiency.
Ziemann Holvrieka supplies both standard solutions and custom-designed stainless steel tanks and systems that meet the highest safety standards and integrate seamlessly into your processes.
Our services for the petrochemical industry
Storage tanks
Our storage tanks are designed for the safe storage of crude oil, intermediates, and petrochemical liquids. Up to a diameter of 7.5 meters, tanks can be fully manufactured as one-piece units in the factory; larger dimensions are realized through flexible on-site assembly.
Designs comply with standards such as API 620/650, PED, and ASME, with ATEX-compliant configurations available. The focus is on maximum safety, corrosion resistance, and verified material quality and leak tightness.
Silos
Our silos reliably store bulk materials such as catalysts, sulfur granules, or additives. Designed according to Eurocode 3 and available in ATEX-compliant design, they are built for robust and long-term operation.
Optional discharge systems and sensor technology improve material flow, level control, and process monitoring.
Tailor-made tanks
Whether hydrogen, CO₂, or aggressive petrochemical media – we supply tailor-made special tanks for demanding applications and extreme conditions.
All solutions are designed to meet environmental and safety requirements and can be seamlessly integrated into complex process chains.
Process tanks
Our process tanks are designed for reaction, mixing, and distillation processes, ensuring reliable and controlled operation. They are equipped with agitators as well as integrated heating and cooling systems tailored to process requirements.
All tanks are designed to be pressure-resistant and comply with relevant safety standards. The focus is on stable processes and consistent product quality.
Pressure vessels
Our pressure vessels are capable of handling demanding high-pressure processes such as hydrocracking or gas storage. Certifications according to PED and ASME standards, as well as ATEX compliance for explosive media, are standard.
Our design and manufacturing aim for maximum strength and process reliability, supported by comprehensive testing and documentation.
Tank accessories
In addition to their various applications, our tanks and systems can be equipped with a wide range of accessories tailored to your individual needs:
Walkway systems for safe access, insulation, agitators, and structural steel solutions in stainless or carbon steel, as well as skid-mounted units.
Spare parts and global service ensure availability, reliable operation throughout the product lifecycle, and predictable costs.
Process plants
Our process plants provide complete solutions including engineering, automation, and installation. They integrate safety systems and explosion protection into a fully coordinated concept.
The result is fast, safe commissioning and reliable process operation.
Safety & Compliance
Our tanks and systems meet the relevant petrochemical industry standards – including complete documentation and testing. This ensures legal certainty, supports permitting processes, and maximizes plant safety.
