Selected issues of prestressed concrete containment tanks for the storage of liquefied gases design in accordance with EN 14620
Languages of publication
In 2014, a new tank for the storage of liquefied ammonia (capacity 22 000 m3) was built for the chemical industry company ‘Grupa Azoty S.A.’. The LNG terminal in Świnoujście, where two large capacity containers (160 000 m3 each) were built, is almost finished (2015). In both cases, prestressed concrete was used to build a secondary (outer) containment tank.This paper is devoted to general concepts and design considerations for secondary cylindrical, concrete containers for the storage of refrigerated, liquefied gases with temperatures between 0°C and –165°C, according to EN 14620.
