Transport engineering specialist Mammoet, on behalf of Linde Engineering, has moved and installed equipment for a carbon capture and utilisation (CCU) unit at a cement plant in Triefenstein, Germany.
With a feasibility study conducted a year prior to the work commencing, Mammoet utilised a 3D model of the existing cement plant to visualise the complex processes, space requirements, and potential interfering edges at the confined construction site. Also early in the project, Mammoet’s team provided suggestions for adapting the layout of the CCU plant to the requirements of the installation.
A 750-tonne crawler crane was used to lift and install large components, with three-dimensional planning enabling the crawler track for the crane to be kept as small as possible.
First, the absorber column – which weighed 100 tonnes and measured 55 m in length – was erected on the pre-dressing area via tandem lift, with the load then swung almost 180 degrees on the hook of the crawler crane and moved approximately 20 m to the installation position. There, the column was carefully guided behind a building before being positioned, aligned, and bolted onto the foundation in the steel structure.
Once the absorber column had been moved, Mammoet installed a 178-tonne heat exchanger, a 67-tonne stripper column, as well as four tanks which each weighed 72 tonnes.
The crawler crane’s configuration was changed shortly before the project began, which meant that intermediate transport on the construction site was not necessary and, ultimately, time was saved.
Linde Engineering is building the plant and formed a joint venture for the project with Heidelberg Materials, called Capture-to-Use (Cap2U).
Last week, HLPFI reported that Mammoet has been on hand to widen the concourse at Atlanta’s Hartsfield-Jackson International Airport whilst also committing to hydrogenated vegetable oil (HVO).
