During a so-called turnaround, when the production process is shut down at a refinery, we carried out catalyst work. Together with Mourik International (main contractor) we unloaded, cleaned, filled and checked 3 Tubular reactors. This work was carried out safely and on time, within 18 days. The shutdown for the customer was thus kept as short as possible. It concerned 3 reactors with 4500 tubes each, which were filled with catalyst. The work was carried out in a 24-hour work schedule. Compliments to our employees for the excellent execution!
