Side Entry Mixer for Large Storage Tanks

Large storage tanks are widely used in industries such as oil & gas, petrochemical processing, and bulk liquid storage. Due to their large diameter and high liquid volume, achieving uniform mixing inside these tanks can be challenging. Without proper circulation, issues such as temperature stratification, sedimentation, and uneven product quality may occur.

Side entry mixers are specifically designed to address these challenges. Installed on the side wall of the tank, they generate strong horizontal flow patterns that promote circulation throughout the entire tank. This article explains the role of side entry mixers in large storage tanks, how they work, and why they are widely adopted in industrial applications.

Why Mixing Is Required in Large Storage Tanks

In large-capacity tanks, liquids tend to remain static for long periods. This can lead to several operational problems:

· Accumulation of solids at the bottom of the tank

· Inconsistent temperature distribution

· Poor homogenization of blended products

· Increased difficulty during pumping or discharge

Effective mixing is therefore essential to maintain product uniformity and operational reliability. Side entry mixers provide a practical and energy-efficient solution for this purpose.

How Side Entry Mixers Work in Large Storage Tanks

Side entry mixers are mechanical agitators mounted horizontally on the tank shell. The rotating impeller generates axial and radial flow, creating circulation loops inside the tank. These flow patterns help move liquid from the bottom to the top and from the center to the tank wall.

Key Functions of Side Entry Mixers

1. Promoting Effective Circulation

The horizontal flow generated by the mixer prevents stagnant zones and ensures that the entire tank volume is involved in the mixing process.

2. Preventing Sedimentation

By maintaining continuous movement near the tank bottom, side entry mixers reduce the accumulation of solids and sludge, helping keep particles in suspension.

3. Improving Homogenization

In blending or storage applications, side entry mixers help maintain consistent composition and temperature throughout the tank, ensuring stable product quality.

4. Supporting Energy-Efficient Operation

Compared with top entry agitators, side entry mixers typically require lower installed power and can be operated intermittently, reducing overall energy consumption.

Typical Applications of Side Entry Mixers

· Crude oil and fuel oil storage tanks

· Petrochemical and refinery tank farms

· Oil terminals and blending tanks

· Large industrial storage tanks for low to medium viscosity fluids

Their compact structure and flexible installation make them especially suitable for retrofitting existing tanks.
