Stock Photo - 15 April 2021, Saxony-Anhalt, Leuna: At the TOTAL refinery in Leuna, large storage tanks containing various intermediate products that will later be blended into finished products, such as gasoline, diesel and heating oil, stand behind kilometers of pipes. Preparations are currently underway at one of Europe's most modern refineries for a general inspection lasting several weeks, which is scheduled to begin in early May. The third scheduled general maintenance with complete shutdown was supposed to take place last year, but had to be postponed due to the first wave of coronas. Total expects about 5000 additional forces from all over Europe. Photo: Waltraud Grubitzsch/dpa-Zentralbild/ZB. - Leuna/Saxony-Anhalt/Germany
