The project
The plant was situated adjacent to live pipe racks, railway spur lines, and plant roadways as well as a warehouse and auxiliary buildings that had to remain operational during the project.
Shell decommissioned the plant, which involved the removal and disposal of process chemicals through the isolation, purging and cleaning of all equipment, tankage, and piping. In addition, Shell undertook the physical disconnection and air-gapping of all decommissioned feed, product, and utility lines from adjacent pipe racks.
Delsan-A.I.M. Environmental Services Inc. (Delsan-A.I.M.) completed the decommissioning and demolishing of a polypropylene plant located in an operating oil refinery in two (2) phases. The plant contained process equipment, structures, and buildings along with pipe racks, piping and conduits that were used in the production process.
Delsan-A.I.M. prepared the plant for demolition by verifying and validating that all disconnects, and air-gapping had been completed and by performing a site inspection to confirm that all residual products had been removed.
Delsan-A.I.M. undertook the remaining decommissioning work to ensure that all designated substances, such as asbestos-containing materials, and any remaining hazardous materials were abated prior to the commencement of demolition operations. The demolition work was completed to top of slab-on-grade by employing mechanical methods in accordance with engineered guidelines using conventional equipment such as large excavators equipped with specialized attachments.
Any structures that could not be safely demolished by conventional means due to their height or location with respect to operating services or facilities, were either lowered in sections using a mobile crane and small demolition equipment, or control dropped in accordance with detailed engineered procedures. All demolition materials were shipped off-site to licensed recycling or disposal facilities except for the concrete rubble, which was crushed, stockpiled, and reused on site.
