Demaco Phase Separator

It’s all about Cryogenius.

 
Phase separator

Within most cryogenic infrastructures, often due to heat inleak, some gas-forming takes place. As a result, warmed-up liquid gas becomes impure and mixes with gas bubbles. This causes problems when using liquid gas, for example, in machines.

To ensure that cold liquid gases remain as pure as possible, it is recommended to use a phase separator.

Demaco phase separator:

  • Allows the pressure to be regulated to a desired level
  • Enhances the quality of liquid gases
  • Safeguards an adequate supply of liquid gas

How does it work?

The phase separator features an internal storage vessel, in which liquid gas is temporarily brought to a standstill. Because gas is lighter than liquid, any gas bubbles rise naturally when the flow stops (or is minimal).

At a preset liquid level, and thus a preset volume of gas, a gas vent is opened at the top of the vessel, releasing the gaseous portion. At the bottom of the vessel, the pure liquid gas can now be extracted at the customer’s specified output pressure.

The correct control of the filling valve is essential for the phase separator to operate correctly. To ensure it opens at precisely the right time, the phase separator features a level sensor and a level controller

Specifications

Demaco’s phase separators are entirely custom-made to ensure that the construction and dimensions perfectly fit the project.

In recent years we mainly supplied phase separators with a capacity of 40 or 100 liters. In most cases, these sizes perfectly meet the requirements of our customers. If required, we will design and build a phase separator to customer specifications.

Phase separator application

The phase separator guarantees the supply of pure liquid gas and is therefore used in various industries. It is essential for most cold liquid gas users that the gas is pure and of high quality, without gas bubbles.

The industries in which phase separators are used most often are the automotive, electronic, food, medical and pharmaceutical industry. All these industries use liquid nitrogen systems extensively, in which both temperature control and an excellent liquid gas quality are essential for proper operation.

Accessory products

Each phase separator features a level sensor and a level controller to ensure it functions correctly. The level sensor measures the height of the liquid in an internal buffer vessel, which in turn allows the level controller to operate the exhaust valve (GN2) of the phase separator.
