Choosing Between Horizontal and Vertical Storage Tanks

Choosing Between Horizontal and Vertical Storage Tanks

  Storage tanks are vital for holding liquids and gases, with the main types being horizontal and vertical. While both serve similar purposes, they differ notably in shape, footprint, and design requirements. Horizontal storage tanks, with their low-profile design, are ideal for large-volume storage and easy maintenance. In contrast, vertical storage tanks, which save space, are suited for environments where height is a factor. Understanding these differences helps in selecting the right storage...

Two Phase vs. Three Phase Separators: Key in Fluid Separation

Two Phase vs. Three Phase Separators: Key in Fluid Separation

In the oil and gas industry as well as in chemical production, separators are key equipment to ensure the efficiency of fluid processing and the stability of processes. The main task of separators is to effectively separate different phases (gas, liquid, solid) in mixed fluids, thereby achieving fine processing and handling of raw materials. According to the different phases separated, separators can be divided into two-phase separators and three-phase separators. Two-phase separators are used for...
