Reconstruction and Modification of Existing Desulphurisation Technology

The subject of the work is the supply of technological equipment for unloading of the Sorbacal wagons and transport to the storage silo and the implementation of SO1, SO2, and SO4 buildings. Another operational set is PS01 – Pneumatic transport leading from the unloading point (rail transport) to the silo and technological equipment of the silo.
Part of our delivery is the foundation and construction of a steel structure supporting a 40m sorbent silo and construction of buildings for the necessary technology and a new electrical substation.
The data for the elaboration of the construction part of the project did not sufficiently map the existing foundation conditions. After a test borehole and examination of the samples, it was found that the foundation joint did not have sufficient load capacity. For this reason, it was necessary to rework the static assessment of the foundation of the building. Subsequent drilling and other construction works took place in a confined space between the existing lime silos and the old compressor room.
The supporting structure under the desulphurization sorbent silo forms a massive steel structure based on 4 piles of the depth up to 17 m. A substantial part of the work at heights was carried out in a climbing manner.
Operational set PS01 – Pneumatic transport consisted of modifications of filling stands, the addition of new pipes, including abrasive resistant basalt bends, and equipment the silo technology.
The capacity of the transport route of the Sorbacal SP material is 15 – 20 t/h, the transport air for one filling point is 930 m3/h, the pressure is 0,2 MPa.
One route is 60 m long, of which 39 m is the elevation gain.
The pneumatic transport leads into the silo via a vortex separator. The silo is constantly under-pressured thanks to a mounted filter with an output of 3 000 m3/h.
