Overview

A Titanium Tower Vessel is a type of pressure vessel or tower equipment fabricated from titanium or titanium alloys. Due to titanium's exceptional corrosion resistance, high strength-to-weight ratio, and excellent performance in aggressive environments, these vessels are widely used in industries where conventional materials such as carbon steel or stainless steel cannot meet durability or purity requirements.

Titanium tower vessels are commonly applied in the chemical, petrochemical, and oil & gas industries for processes involving separation, storage, and treatment of gases and liquids under high pressure and elevated temperatures. They are also used in high-purity chemical production where contamination and corrosion must be strictly controlled.

Titanium's unique properties-including low density, outstanding corrosion resistance, and high mechanical strength-make it an ideal material for tower-type process equipment operating in harsh media such as chlorides, seawater, and acidic environments.

These vessels are typically designed and manufactured in accordance with international standards such as ASME Boiler and Pressure Vessel Code (Section VIII, Division 1) and TEMA standards, ensuring reliability, safety, and long service life.

Main Components

The configuration of a titanium tower vessel depends on the specific process design, but generally includes the following key components:

1. Shell

The shell is the main cylindrical body of the vessel that contains the process medium. It is usually fabricated from titanium plates or titanium alloy plates and designed to withstand internal pressure, temperature, and corrosion.

2. Heads

Heads are the end closures of the vessel. Common types include:

Elliptical heads

Hemispherical heads

Torispherical (dished) heads

These provide structural strength and allow access for inspection and maintenance.

3. Nozzles

Nozzles are inlet and outlet connections that allow process fluids to enter or exit the vessel. They are welded to the shell or heads and may be constructed from titanium or compatible alloys depending on the service conditions.

4. Supports

Supports are used to stabilize and carry the weight of the vessel. Typical support structures include:

Skirt supports

Saddle supports

Leg supports

They are commonly fabricated from carbon steel or stainless steel with appropriate insulation or lining.

5. Internals

Internal components improve mass transfer or separation efficiency inside the tower. Typical internals include:

Trays (sieve trays, valve trays, bubble cap trays)

Structured or random packing

Demisters / mist eliminators

6. Instrumentation

Process monitoring devices such as pressure gauges, temperature sensors, and flow instruments are installed to ensure safe and stable operation.
