Petroplus Coryton

TEL Remediation Project In Coryton Essex

The project consisted of dismantling, decontaminating and disposal of 2 x 8 Metre horizontal Tetraethyl Lead storage tanks. The Tetraethyl lead was transferred into ISO modules for recovery at the manufacturing facility in the UK.
All associated pipe work, blending units and kerosene scrubbers were drained of contaminated liquids and removed under a cold work permit which forbids any use of heat generating equipment.

Second stage was to remove the storage tanks from their base structures and to be transferred by low loading equipment to an area for safe decontamination.
Once storage tanks are sited work is then carried out gas free the vessels, this is to enable cold cutting of an access door to gain entry to remove any residues of scales and sludges. The highly toxic scales and sludges were removed form the storage tanks and placed into certified 5 Tonne ISO modules for offsite disposal at the manufacturing facility in the UK.
After the vessel is free from contaminates, hot work will be used in the form of an oxygen/propane gas axe, the vessel will be hot cut into manageable sections for decontamination of the steel by way of de-scaling and heat treating of the steel, all pipe-work is cut into 1 metre sections and stacked ready for decontamination, the pipe-work is manually de-scaled and heat treated, this process then converts the lead from its organic stage to inorganic for safe disposal at a certified smelting facility.

Third stage is the removal of all buildings, bund walls and any contaminated below ground facilities, all concrete and rubble is tested for presence of lead and sent offsite for disposal.

Both remediation sites are cleaned and tested and certified lead free before handing back to the refinery.
Crests work is carried out under CLAW (Control of Lead at Work 2002) with daily safety toolbox talks, HSE audits and daily atmosphere analysis.

The project was successfully completed without any Safety, Health or Environmental incidents.
