22nd Novemver 2009. DTEC completed one of its largest Turnaround Events to date for Petroplus Refining at Coryton Refinery. This was a multi column workscope across several units including the Alkylation plant. Initial work was to open columns for inspections and perform scoped work including a partial revamp of the Acid Settler. Inspections determined a wide variety of emergent work for which DTEC provided emergency supply of tower attachments, trays and hardware. Additional resources were provided to perform the additional work which included tray ring removals and installations, fully welded tray installations and bolted internals changeouts. The work was completed in 19,400 accident free hours with peak manning of 48 men.
