Classified fluids, high pressures, very low ambient temperature or high operating temperature, the storage tank is an item of equipment subject to the European Pressure Equipment Directive.
Thermal Specifics :
Within the framework of the rehabilitation of a Natural Gas Liquefaction Complex located in North Africa, Quiri, a specialist in heat exchangers and pressure vessels, carried out the mechanical design and fabrication of twenty-four (24) tanks.
6 x CLD (Cold Liquid Drops) recovery tanks. (Blow Case Vessel CLD 650) (Cold Liquid Dropout) with cradle and fire protection
6 x propane refrigerant recovery tanks. (Blow Case Vessel PR 660) (Propane Refrigerant) with cradle and fire protection
12 x air storage tanks for LNG tanks.
These tanks were supplied by Quiri as part of the renovation program of the complex.
