REQUIREMENT
Steel structure for a complex process plant
As part of a new bioethanol plant, the Swiss chemicals group Clariant AG planned to construct a multi-storey steel structure for the distillation area. The supporting structure was required to accommodate process plant, pipework, platforms, stairways and a crane area across several levels, whilst integrating seamlessly into the overall design of the industrial plant.
The steel structure had to safely bear high plant loads whilst ensuring access for operation, maintenance and assembly. Furthermore, the interfaces with the process plant and the assembly procedures involving other trades had to be coordinated at an early stage in order to meet the tight schedule of the overall project.
The plant was to operate continuously 24/7 and formed part of an industrial project with an investment volume of more than 100 million euros.
RESULT
Seamless integration into a complex industrial project
Astron constructed the steel structure for the distillation area within the industrial site, which covers approximately 100,000 m². The open, hot-dip galvanised steel structure, featuring multiple working levels, integrates process plant, pipework, platforms, stairways and a crane area into a functional, comprehensive solution for operation, maintenance and servicing.
Astron’s engineers developed the complete steel structure and coordinated all interfaces with the process plants as well as with the design partners and trade contractors involved. Engineering, fabrication and assembly were seamlessly integrated. Right from the planning phase, the structural framework, plant integration and assembly processes were coordinated in detail. This reduced interfaces on site, ensured planning reliability and supported the precise and on-schedule implementation of the project.
Steel structures for industrial plants
Industrial plants place particular demands on steel construction. Multi-storey load-bearing structures must safely support processing facilities, pipework, platforms, stairways and maintenance areas, whilst at the same time enabling precise integration into complex overall projects. High plant loads, numerous interfaces and close coordination with various trade contractors must be taken into account as early as the planning phase.
Astron develops and constructs steel structures for industrial and process plants in Europe and beyond. Engineering, fabrication and assembly work together seamlessly, laying the foundation for precise plant integration and on-schedule project delivery. Open steel structures with multiple working levels enable flexible maintenance and access areas, and support the safe operation of complex industrial plants.
Main contractors benefit from an experienced steel construction partner who precisely plans, manufactures and assembles sophisticated load-bearing structures. Early coordination of interfaces, digital planning and end-to-end project management ensure planning reliability and reduce the need for coordination during execution.
