Our client is a specialist in the drying of petrochemical units. They needed to provide an innovative solution for scraping and drying operations during the planned shutdown of the alkylation unit at a refinery. The shutdown required effective drying and inerting of the unit’s lines and capacities within the operational deadlines.
Successful completion of the operation was essential. Draining the remaining water from the pipes and capacities is a very important step to limit corrosion and leakage risks of the alkylation unit, during the 7-year operational cycle.
The idea was to offer a solution that would reduce operating costs and environmental impacts compared to traditional techniques, while ensuring superior efficiency
