Design of Nitric Acid Storage Tanks | consultancy Services

Nitric acid storage tanks are specially designed containers used for storing nitric acid, a highly corrosive and hazardous chemical. Here's an overview of the components and considerations involved in their design:

Design Codes & Standards: Tanks for storing nitric acid must adhere to specific design codes and standards set by regulatory bodies like the American Society of Mechanical Engineers (ASME) or the American Petroleum Institute (API).
Design of Shell: The shell of the tank needs to be designed to withstand the corrosive nature of nitric acid and to withstand the internal pressure exerted by the stored acid.
Design of Roof: Similar to the shell, the roof of the tank must also be designed to prevent corrosion and to bear any external loads applied to it.
Design of Bottom Plate: The bottom plate of the tank should be designed to provide structural integrity and prevent leakage or rupture.
Design of Wind Loads: Tanks located in areas prone to high winds need to be designed to withstand wind loads without collapsing or becoming unstable.
Design of Seismic Loads: Similarly, tanks in seismic zones must be designed to withstand seismic forces without failure.
Anchorage Design: Tanks need to be securely anchored to prevent movement or overturning during high winds or seismic events.
Design of Foundation: The foundation of the tank must be designed to support the weight of the tank and the stored nitric acid while ensuring stability and preventing settlement.
Design Calculations: All design aspects, including structural integrity, load-bearing capacity, and material strength, require thorough calculations to ensure safety and compliance.
General Arrangement (GA) Drawing: GA drawings provide an overview of the tank's layout, dimensions, and key components.
Detail Drawings: Detailed drawings provide specific information on each component of the tank, including connections, joints, and supports.
Material Selection: The choice of materials is crucial in nitric acid storage tank design. Materials must be resistant to corrosion by nitric acid and compatible with the specific concentration and temperature of the stored acid.

Overall, the design of nitric acid storage tanks requires careful consideration of various factors to ensure safety, compliance with regulations, and protection of the environment and surrounding infrastructure.
