Amine Converter Replacement & Heater Stack Demolition

At a petrochemical refinery in the Southwest, the demolition of two heater stacks and the replacement of an amine converter tower presented significant logistical challenges.

To facilitate the replacement, a 750-ton gantry system was employed to transload the new amine converter, measuring 75’ L x 12’ W x 12’ H, from pre-installed concrete staging piers to the transporter for delivery to the crane site. This gantry proved to be a cost-effective solution compared to deploying more lifting equipment.

For the actual replacement, the team utilized the 1,500-ton VersaCrane™ TC-24000, known for its ability to maneuver in tight spaces and its reduced matting requirements for ground bearing pressure, alongside a 500-ton Liebherr LTM 1400-7.1 for tailing operations.

The 500-ton crane was also used in the demolition and replacement of the heater stacks. Upon completion, the existing amine converter was set back on the pre-existing piers using the gantry, preparing it for future demolition.
