Ineos Nitriles, Seal Sands
20,000 tonne crushed for re-use
25,000 tonnes of scrap recycled
Felling of 17 stacks
Removal of 7 jetty loading arms
Hughes and Salvidge won the Ineos Nitriles project with Ineos. The project included asbestos removal works, a secondary drain-down of products, asset recovery, the demolition of hundreds of tanks, vessels and reactors/stacks, removal and disposal of extensive pipework, stripping of two jetties, the demolition of a boiler compound, and other buildings and structures on the 155-acre site.#
A few sections of the plant were known to still contain residual product, and the Hughes and Salvidge team worked carefully and diligently to ensure that these sections were drained down and the product safely contained for subsequent disposal as hazardous waste.
Some live assets needed to remain and so needed to be protected and worked around. This included Ineos assets, as well as the Sembcorp easement pipe rack which intersected with the main Ineos C-Street pipe rack that was demolished. Careful separation works were undertaken by hand, prior to mechanical demolition by heavy plant continued the task.
Amongst the demolition works included the felling of 17 stacks ranging from 30m to 92m in height and numerous crane lifts including the removal of 7 jetty loading arms from the two jetties. Some of the stacks contained RCF/Cristobalite which needed to be managed and disposed of with the necessary control measures in place.
Around 20,000 tonne of hard inert arisings was crushed for re-use on site, being used for backfilled voids and sumps, and for grading the site genuinely to the desired levels.
Over 25,000 tonnes of scrap metals were removed from the site for recycling.
