Air Separation Unit (ASU) Decommissioning Project

Universal Cranes provided technical dual lift to remove air units and additional equipment.

Client: Xtreme Engineering

Date: October 2021

Project: Air Separation Unit (ASU) Decommissioning Project

Scope: The scope of the project was the deconstruction of air separation unit cold box distillation tower and the associated equipment.

Overview: The air units were constructed in 2005 by Air Liquide at Rio Tinto’s Alumina Refinery to supply oxygen to the process.

The most challenging task required the use of our 450t Grove to lift the 47m high cold box down in two sections. The team had to cut the cold box in half, the two sections weighed in at 44 tonnes (higher piece) and the lower piece at 60 tonnes. These sections were then tailed from the vertical into the horizontal position with assistance from the 300t Liebherr in preparation for the sections to be transported to their final destination in India.

Lots of spectators came out to watch the milestone moment as the two pieces were lifted down safely.

Key Equipment Utilised: Grove GMK 7450, Liebherr LTM 1300/1, Grove RT890E, MAC 25 Franna
