Cone-bottom tanks are generally used in process applications where total drainage of the tank is required. Typical applications would include the storage of heavy materials and materials prone to sludging, which are difficult to drain out of upright tanks. Cone-bottom tanks are also ideal for dry materials, such as grains or cattle feed as they can be 100% drained out of the tank with a flange or slidegate at the bottom of the tank. In addition, materials that require separation can be handled with a decant fitting to remove the liquid from the solids. Let’s take a look at some key considerations for evaluating cone-bottom tank storage solutions — and attractive alternatives.

Seismic codes govern structural design to prevent damage to buildings and structures during an earthquake. It’s common knowledge that buildings must conform to specific seismic codes, but your chemical storage tanks also have seismic regulations. Any facility in a seismically active region, including everywhere along the Pacific Rim, must pay careful attention to the safety measures established in the International Building Code.
Chemical leaks present several major challenges for your facility. They can cause damage to storage systems, employees, and the environment. Repair and cleanup costs can be expensive, and the leaked chemical is wasted.
Maintaining the proper temperature of a chemical inside a high density crosslinked polyethylene tank can be critical for safe and effective storage. For example, sodium hydroxide and caustic soda need to maintain temperature to prevent crystallization at lower temperatures.

You’ve heard the adage, “if a job is worth doing, it’s worth doing right.” Poly Processing believes this to be true 110% of the time when it comes to containment. Every single piece of a tank system needs to be completely secure to protect your workspace, your employees, the environment, and the chemical being stored. When you install a tank-within-tank or double wall storage tank system like the SAFE-Tank with a sidewall fitting, it may be important to also install a bellows transition fitting. The bellows fitting lets you safely connect the primary tank with the secondary containment tank.

With over 50 years of experience in creating tanks, fittings, accessories and other materials that ensure your chemical storage solution is safe and tailored to the chemical you are storing, we understand the importance of using the right products for your chemical. We’ve learned how the most popularly stored chemicals, like Sulfuric Acid, Sodium Hypochlorite and Hydrochloric Acid, react to improper storage systems. One part of those tank systems that is crucial is a tank’s gaskets. The tank’s gaskets act as a mechanical seal with a particular fitting to prevent leaks or spills. It is very important to make sure the gaskets and bolts used on your storage tanks are in compliance with what is needed to protect your tank fittings from corrosion caused by reactive chemicals.

You need to know how much chemical is in your storage tank so you can order more product at the right time to continue business without missing a beat. Not only that, but certain chemicals have to be stored at specific levels to maintain their properties. Replacing the chemical too early or too late can stall your operations, ruin your inventory, and impact your profits.
If you aren’t increasing your chemical storage capacity, it might be time to reevaluate your storage strategy. Over the last couple of years, many Poly Processing customers have shifted their approach to storing chemicals. They are increasing their total volume capacity in response to many of the market’s trends. External factors, such as the war in Ukraine and supply chain issues, have a trickle-down effect that impacts companies that need to buy and store chemicals. These companies are discovering that it makes good business sense to upsize their chemical storage capacity — both from an operational perspective and a financial one. Should your facility increase your chemical storage capacity? Here are some compelling reasons it might make sense for you to upsize.

When you design a chemical storage tank, it’s commonplace to request extra or "spare" fittings in the sidewall. These fittings aren’t designated for anything specific, but at some point you might need to add another accessory to the tank. It’s convenient to have that fitting already installed and ready to go. This is a common practice, but it’s a potentially hazardous one. Every time you penetrate the sidewall of a tank, you introduce another potential leak. Fittings have gaskets that need to be maintained and monitored for cracking. Over time, fittings and gaskets can degrade and require replacement. The fittings also need to have the proper torque on them for a proper seal.

Bulk stored chemicals can become contaminated from two major sources: debris and moisture. As the product is emptied from the chemical storage tank, dirty air and moisture can be drawn into the tank. Temperature fluctuations can also cause the tank to expand and contract, so that it “breathes” contaminants in and out. Maintaining chemical purity is essential in many industrial chemical applications, such as computer chip manufacturing, food processing, clean in place, and pharmaceutical manufacturing. Contaminated chemicals can become less effective, and more hazardous to your storage equipment. To prevent contamination, Poly Processing often recommends installing special accessories. Tank vent dryers and desiccant filters may be your best choice for keeping moisture out of the chemical storage tank.

With some chemicals, it’s critical to keep them cool because they will lose their concentration when they heat up. Sodium Hypochlorite is a prime example of that. As it heats up, it starts to lose its strength, and it begins to release gas and free radicals. Its strength can diminish dramatically with heat and UV. So it’s important to keep the chemical as cool as possible from the moment it arrives at your facility.

Some companies need to place their chemical storage tanks underground because of space limitations, or for aesthetic reasons. Steel tanks and reinforced tanks are built to withstand the external pressure that is applied underground, but what about lightweight plastic tanks? While plastic storage tanks have many advantages over other tank materials, polyethylene is not the solution for underground storage. Here’s why.

Various types of chemical storage systems have handrails along the top of the tank, but Poly Processing tanks don’t. Polyethylene tanks can’t support handrails, and the tanks shouldn’t be walked on. The domed surface can be very slippery, and the plastic can become brittle over time and possibly crack under a person’s weight. So how do you safely inspect manways, check gauges, and service level sensors or mixers?

There are several types of chlorine sources that water treatment plants can use: chlorine gas, liquid sodium hypochlorite, or onsite production. Chlorine gas can be more cost effective, but a growing number of states are converting to bulk sodium hypochlorite or bleach. If chlorine gas is more economical, why would water treatment plants convert to sodium hypochlorite?
