Gas Module

Reactions with gases made easy

Gas Module for accurate dosing of gases

This module enables precise dosing of various gases, offering a seamless integration of gas handling capabilities into your workflow. It supports a wide range of gases, including hydrogen, nitrogen, oxygen, and more, allowing you to tailor the gas environment to meet your specific experimental requirements. The Gas Module seamlessly integrates with other ThalesNano instruments and modules (including the H-Cube Pro and the Phoenix flow systems), allowing for comprehensive control of your laboratory processes.

How does the Gas Module work?

The module can work easily with the H-Cube Pro and with the Phoenix Flow Reactor to allow different gases to be used up to 100 bar pressure. Reactions, such as carbonylations or oxidations, can be performed at high pressures, widening the reactor’s chemistry ability significantly.

  • A gas source, typically a gas cylinder, connected to the Gas Module lets out a gas flow that should be in a pressure range between 25 and 140 bar.
  • Users can select the applicable gas from the list of the Gas Module or set the properties of a new gas.
  • The built-in mass flow controller ensures the accurate dosing of the gas, even at high pressure.

Features of the Gas Module

Versatile: 14 gases in one device: compressed air, O2, CO, ethylene, SynGas for hydroformylations, CH4, C2H6, He, H2, N2, N2O, NO, Ar, CO2 (after preheating); other gases with well-known thermodynamic properties and compatibility can be introduced

Powerful: Capability for performing heterogeneous reactions at up to 100 bar pressure

Robust: Materials of construction consist of either 316 stainless steel or Hastelloy

Gas Module Plus

The Gas Module Plus is purpose-built for accommodating larger quantities of gases. It seamlessly integrates with ThalesNano reactor systems, such as the H-Cube Pro and the Phoenix Flow systems. This module guarantees precise and controlled gas dosing at flow rates of up to 1 NL/min, extending the gas flow range beyond that of the original Gas Module.

Use the Gas Module with the H-Cube Pro

When the Gas Module is connected to the H-Cube Pro, it allows the introduction gases, such as carbon monoxide, oxygen or syngas.

Connect the Gas Module to Phoenix flow systems

Use multiple Gas Modules connected to the Phoenix reactor to set up a system for catalytic reactions with different gases.

FAQ

No. For safety reasons, when the Gas Module is connected to the H-Cube Pro, its software automatically blocks the generation of hydrogen.
No. It does not generate any gases, only regulates the amount of gas coming from a cylinder.
Only one cylinder can be used at a time, so the amount of gases depends on the gas type in the cylinder: only gas mixtures such as syngas can be introduced.
Only gases can be introduced into the Gas Module™. To avoid any condensation, you have to make sure the pressure you are using is under the vapor pressure of the gas. Reaction pressure has to be at least 15 bar lower than the pressure of the tank.

The vapor pressure of each gas is given in the below table.

The Gas Module does not have a compressor. Please ensure the gas source is able to maintain the pressure above the inlet pressure of the H-Cube Pro or the Phoenix Flow Reactor during the reaction. The reaction pressure is set on H-Cube Pro or on the Pressure Module connected to the Phoenix Flow Reactor, between atmospheric pressure and 100 bar. The gas cylinder pressure must be at least 25 bar higher then the inlet pressure of the reactor.
No. Only dry gases can be introduced into the Gas Module. The use of wet gases is not allowed.
No. The H-Cube Pro is equipped with all the software and hardware tools to be connected to the Gas Module and being able to control it.
You will need a gas source (typically a cylinder) with a high pressure regulator attached. The external fitting should be able to connect to a 1/8 stainless steel tube.
All gas regulators can be used if their parameters fit to the specifications of the Gas Module. Recommended gas regulators: N2 regulator: Linde C200/1A-200B, O2 regulator: Rhöna EN OX 03-10, H2 regulator: Linde fdr-200-100-380-h
Only the gas flow rate range: the Gas Module can ensure 0-100 NmL/min gas flow rate, while the Gas Module Plus can be used in the 100-1000 NmL/min gas flow rate range.
