SPHERICAL STORAGE TANKS
If the liquefied gas storage is designed to meet processing or distribution needs that require relatively smaller capacities, we normally use spherical pressure tanks. Duro Felguera Energy Storage is specialised in the execution of the engineering, design and construction of this type of equipment, and its references include a wide range of products, capacities, pressures and temperatures.
Since the commencement of its activities, Duro Felguera Energy Storage has supplied more than 200 spherical tanks worldwide for all kinds of products and storage conditions.
Two types of spherical tanks may be distinguished based on the storage temperature: at room temperature or semi-refrigerated. Selecting one or the other may depend on the balance of the product vapour pressure and the volume of the sphere. The aim is to optimise the mechanical design by limiting the thickness of the stainless steel enclosure. Company’s reference in this field includes the storage of liquefied gases in spherical tanks with capacities ranging amongst the highest worldwide, reaching up to 10,600 m3.
VERTICAL STORAGE TANKS
Duro Felguera Energy Storage designs, supplies and constructs the complete range of vertical storage tanks existing on the market, and can adapt the designs to the required capacities and the specifications of the product to be stored.
We usually supply this type of products according to API 650, 620, EN 14015, AWWA and other specifications, but we can also comply with customers specifications and local regulations.
If the customer so requires, Duro Felguera Energy Storage can propose the material and the design code that best fits the ratio between the customer’s investment and the quality of the supply, and can construct customised facilities.
Since the commencement of its activities, Duro Felguera Energy Storage has supplied more than 1500 vertical tanks worldwide for all kinds of products and storage conditions.
Types of tanks
- Conventional fixed-roof tanks
- Fixed-roof tanks with internal floating roof
- Floating-roof tanks
- Refrigerated and cryogenic tanks
- High temperature tanks
HORIZONTAL STORAGE TANKS
Duro Felguera Energy Storage designs, supplies and constructs (if the size requires field construction) all varieties of horizontal storage tanks, whether for LPG, any other type of liquid or gas fuels, cryogenic or chemical products storage, etc. Considering the kind of storage, we can construct and deliver horizontal containers that may be buried below or set up above the ground, whether single of doubled walled.
