Treatment of the 220,000 tons of refinery sludge, historically landfilled in two natural lagoons and remediation of the sites

Project Description:

The green project consists in pumping and excavation of 220,000 tons of refinery sludge, deposed into two natural lagoons. The sludge was separated by tri phase centrifugation and fractions were further treated. The contaminated solid were treatment by direct heat thermal desorption technology, at a cleanup limit of 200 mg/Kg TPH.

The treated material was used for backfilling. The contaminated sites were entirely cleaned and closed without future environmental liabilities. 

Scope of work

  • Basic and detailed design packages
  • Permitting, including Building permit and IPPC permit;
  • Construction
  • Project management and construction supervision;
  • Pre-commissioning and start up
  • Operation;
  • Site backfilling
  • Closing
