The Storage tank is continuously evolving, with new innovative trends continuously appearing and changing it into what it is now and, ultimately the future of the industry.
Storage tanks are available in many shapes vertical and horizontal cylindrical, open top and closed top, flat bottom, cone bottom, slope bottom and dish bottom. Large tanks tend to be vertical cylindrical, or have rounded corners transition from vertical side wall to bottom profile, to easier withstand hydraulic hydrostatically induced pressure of contained liquid.
Tanks resting on the ground have flat bottoms and colon while those supported on towers have either flat or curved bottoms. Standpipes, which are usually cylindrical shells of steel or reinforced concrete resting on the ground, are frequently of great height and comparatively small diameter. They are built to contain water for a distribution system, and height is required to maintain pressure in the system.
Tanks for other liquids and for gases, where storage is more important than pressure, are generally lower and of greater diameter.
Storage Tank Security
Storage tank security is a major concern, not only within the oil and gas industry, but also in the water industry. It is critical that storage tanks be protected from tampering, vandalism including accidental harm to storage tank facilities. It is also essential to ensure that the area is secured to keep the general public safe, especially in the case of chemical storage tanks- the first step is to erect a fence or a barricade, a warning sign, positioning of the storage tank in a secure place, including a video surveillance, and tank locks.
When buying a Storage Tank
One of your first tasks is to identify how the storage tank will be utilized. Do you require water tanks for a manufacturing plant? Perhaps you are in need of large fuel tanks that will provide storage for gasoline, such as those found at gas stations or convenience stores. When home heating is the goal, looking at the various types of natural gas tanks should be your focus. Once the purpose for the tank is determined, it is easy to concentrate your attention on what type of storage device you will need.
The size of the storage tank is another key consideration. In general, models that are designed for home use tend to be smaller, while those employed at manufacturing sites will be larger. The idea is to determine how much of the stored fuel or water will be needed to operate for a reasonable period of time, such as a month. With the answer to this in mind, it is easy to look for a storage tank that has the proper capacity. Before making your final purchase, however, make sure the tank size you have in mind will comply with any local laws or regulations.
Along with type and size, you will need to consider the location for the storage tank. Do you envision the tank as setting above ground, like the propane tanks designed for use with private residences? Perhaps the storage tank will reside underground, such as those used to hold fuel for gas pumps.
Of course, if you are purchasing a replacement tank, the answers to all these questions will be apparent, or at least be somewhat helpful in making your new selection. When the capacity of the current tank has proven to be sufficient, the task is likely to be finding a new model of the same size and function. However, if the current tank is not adequate for any reason, the data on the old tank will at least facilitate the task by ensuring you evaluate only storage tank options that are more efficient and have a higher holding capacity than your current unit.
In Africa and the world over use of plastic products is growing, for instance plastic products such as plastic water tanks or a sturdy plastic drum, are ideal for storage in almost every type of residential or industrial situation. Light and long-lasting, they are also preferable to heavy steel drums, and are far easier to carry, transport and relocate.
Water storage tanks are frequently used in South Africa for water conservation, enabling this precious resource to be stored and used for a variety of applications, including irrigation, hydration and hygiene.
There are also many other uses of plastic drums and containers, including dry food and grain storage, animal feed storage, safe storage of certain chemicals, making and storing your own garden compost, storing rubbish at camp sites, outdoor events or construction sites, as planters for produce with deep roots (gas Tanks). Plastic water tanks are lightweight and can often be moved (empty) by hand into position, which is an advantage on rough terrain. Steel tanks must be craned into position.
Plastic water tanks come in green or black, which blends into the landscape/environment better, in addition to having UV-inhibitors in the material to fight sunlight. Plastic water tanks won’t rust over time and have to be replaced, which is one of its best advantages. (Keep in mind that galvanized steel tanks are generally not covered by warranty for rust.)
If you are required to have in excess of 15,000 gallons of water and only have room for one tank; plastic water tanks generally are only made as big as 15,000 gallons. This advantage can be cancelled out if you have a lot of room on your property and can purchase more than one large tank.
Latest Albion Plant Reaches a Milestone
A cost effective, rapidly installed modular tank providing all benefits of a traditional welded tank, but with reduced installation times and far greater flexibility.
The Zipa Tank TM is an innovative approach to slurry storage and leaching tanks that incorporates modular components and mechanical joins to provide all the benefits of a traditional welded tank, but with lower costs, reduced installation times and far greater flexibility.
The latest Albion Process™ plant has reached a milestone at the GPM Gold project in Armenia, with the erection of the oxidative leaching circuit. The plant, owned by GeoProMining Gold LLC, is undergoing construction, and is designed to produce 128,000 oz of gold per year from refractory ore. Xstrata Technology is supplying all plant and equipment for the project, as part of a comprehensive package.
The oxidative leaching circuit consists of twelve of Xstrata Technology’s novel ZipaTank™ modular slurry storage and leaching tanks. Mike Hourn – GM Hydrometallurgy at Xstrata Technology, said the coming together of the leaching circuit at the site was a milestone for the technology. “ZipaTanks™ were developed to simplify the erection of tanks at remote sites. The ZipaTank™ consists of a series of modular panels that are connected using mechanical joins, virtually eliminating welding and scaffolding at site. This greatly reduces installation time, and overcomes quality issues associated with manufacture at a remote site”.
The 12 ZipaTanks™ were fully assembled and hydrostatically tested over an eight week period, using a single crane and a crew of 6 – 8 workers on day shift only. This represented a saving of three months relative to site welded tanks. The ZipaTanks™ are made of stainless steel, with an average capacity of 225m3. The ZipaTanks™ were designed to withstand a magnitude 7 earthquake, due to the highly active seismic setting for the project.
“We are very happy with the site construction progress so far, and are excited to be working toward the commissioning phase for the project”, adds Hourn.
All components of the ZipaTank TM are fabricated under controlled workshop conditions. This ensures a higher quality finish than is possible with field fabrication, and controlled workshop conditions also allow lower cost lined components to be used in construction of the ZipaTankTM without the loss in quality often associated with field applied linings at remote sites.
