Lime Kiln Scrubber Upgrade

Structural Analysis and 3d Modelling

This lime kiln scrubber required replacement to meet increased emissions standards. LHB’s structural engineering team worked closely with the owner’s project engineer to evaluate the existing steel support structure through 3D scanning, Navisworks modelling, and RISA-3D finite element structural analysis software. Analysis was completed for various construction staging scenarios with portions of the structure removed, and scrubber sections removed and added sequentially. Navisworks allowed LHB and and its client to view and manipulate the 3D scrubber equipment and steel representation to evaluate interferences, finalize platform designs, and confirm sequencing of the construction work.
