A.V.Luikov Heat and Mass Transfer Institute of the NAS of Belarus offers consumers hydrogen permeable metal membranes and gas separation installations under a manufacturing agreement, transfer of the software for simulating gas separation processes for various initial conditions under a license agreement and is looking for partners interested in a distribution services agreement.

The separation of a hydrogen-containing mixture using continuous metal membranes is an efficient process that allows one to obtain both impurity gases and high-purity hydrogen.

A.V.Luikov Heat and Mass Transfer Institute of the NAS of Belarus developed flat and tubular (including capillary, 4 mm in diameter) configurations of membranes. Worked out methods for creating palladium-nickel, nickel membranes with a thickness of 80 microns.

To achieve maximum hydrogen permeability, the Institute fabricated binary nickel membranes with a total thickness of 90 µm, consisting of thin (10–15 µm) nonporous selective and porous structural layers of nickel.

In the developed nickel membranes, the activation energy is lower than in palladium-nickel membranes, as a result of which the rate of penetration of hydrogen into them is higher. At the same time, the production of nickel membranes is more economical, and capillary membranes have proven themselves well at high temperatures and pressures (up to 10 atm).

The Institute has created a gas separation installation, designed to study the processes of selection and concentration of components of hydrogen-containing gas mixtures. The installation uses several modules, prefabricated parallel or serial, while it can be implemented accumulative or flow mode. The productivity of the plant is 30–90 l/(m2∙h) depending on the selected mode.

The staff of the Laboratory of Physical and Chemical Hydrodynamics developed the "Membrane Gas Separation 1.0" (MGS v. 1.00) program, which allows simulating gas separation processes for various initial conditions, comparing theoretical calculations and experimental data, and making changes to the operation of the installation to achieve maximum efficiency in the process of separating hydrogen-containing gas mixtures.

Applications: chemical, petrochemical, pharmaceutical and food industries, biotechnology.

The Institute offers interested partners:
* a hydrogen permeable metal membranes and gas separation installations within the framework under a manufacturing agreement;
* computer program "Membrane gas separation 1.0" (MGS v. 1.00) under a license agreement;
* computer program "Membrane gas separation 1.0" (MGS v. 1.00) under a distribution services agreement.

Membrane advantages:
- production from nickel is economically more profitable;
- higher penetrating power;
- large temperature range (before 700°C).

The advantages of the developed membrane gas separation installation are:
- autonomy of work;
- high reliability;
- simplicity in service and a minimum of necessary service personnel;
- quick access to the operating mode;
- automatic mode of operation;
- long service life of membranes;
- modular design and high assembly readiness;
- compactness;
- ecological cleanliness;
- fire and explosion safety.

On the developed gas separation installation, studies were carried out on the permeability of simple gases (He, СH4, N2) at pressures in the pressure channel from 2 to 6 atm. and temperatures up to 700 °C, which showed the impermeability of the nickel membrane to gases other than hydrogen.
