The comprehensive guide to store nitric acid safely in factories

by John Steffen Consultant Chemicals are an indispensable raw material in many industries and storing chemicals safely required a detailed analysis as they could turn to be hazardous when not stored properly. Acids in particular need to stored in the right temperature and in tanks made with the right raw materials so that the acid does not react with the container itself. Acids are widely stored in chemical storage tanks installed in the right environment. Chemical storage tanks are predominantly made from PE (Polyethylene) or PP (Polypropylene). The difference between the two forms of plastics in their hardness; while PE is tough yet light, the PP is hard.PE is abrasion resistant and PP is more suitable for mechanical applications. Hence, you can consider the intended purpose and the properties of the chemical to be stored to choose either PP chemical storage tanks or PE Chemical Storage Tanks. Nevertheless, alloy tanks and stainless tanks are also prevalent.

Nitric acid

The fully concentrated nitric acid(HNO3) is a highly corrosive acid with strong pungent odor. This oxidizing acid is widely used in a number of industries like production of fertilizers, sanitizing, wood working etc.,; making it one of the commonly stored acid in many companies and factories.

Choosing the right Nitric Acid Storage Tanks

Here, we give you the comprehensive guide to store nitric acid based on their concentrations-

If the concentration of the nitric acid is between 0% and 29%, you can robust, high-density polyethylene storage tanks to safely store the acid. It is highly recommended to use only PE tanks for nitric acid with concentration between 30 % and 49% given their effectiveness over other tanks lined with polyethylene. You can also stainless steel, titanium or PVC for milder milder nitric acid with concentration between 0% and 19%. Do not use buna, EPDM and neoprene to store nitric acid as they are prone to corrosion. It is strictly not advisable to store nitric acid in temperatures over 100 Fahrenheit. Based on the need, the nitric acid can be stored in PE tanks of various forms like Classical Top Cylindrical Tanks, Open Top Cylindrical Tanks, Open Top Rectangular and Conical Bottom Tanks.

Searching for best ways to store Nitric acid storage tanks? Hope, we have got you covered. Please ensure all precautionary measures are taken while storing and handling nitric acid to avoid any untoward accidents and injuries.
