Iranian Firm Develops Technology to Separate Carbon Dioxide from Gas Streams

According to the news service of Iranian Vice-Presidency for Science and Technology, separating carbon dioxide from gas streams is of many benefits. Gas separation using new membrane processes is an achievement of an Iranian knowledge-based company.

This technology can prevent the emission of carbon dioxide, while the separated dioxide can be used in other industries.

In most industrial complexes, including power plants, petrochemicals, refineries etc., it is necessary to burn fossil fuels to meet the needs for energy. Fossil fuels are currently the world's most important source of energy as they are available and inexpensive to use, and have a high energy density, meaning they produce a large volume of energy when they are burned.

The gas streams coming out of the chimney of the manufactories contain large volume of carbon dioxide, and the annual discharge of millions of tons of carbon dioxide into the atmosphere destroys the environment and causes serious problems.

The Iranian company has recently launched its work separating carbon dioxide from gas streams in the post combustion using membrane technology.

Through the new technology, the knowledge-based firm saves the country a lot in terms of energy resources. The company generates wealth from greenhouse gases such as carbon dioxide, whose emission pollutes the environment.

Increasing the production of urea, ammonia and methanol in petrochemical companies at a very low energy and water consumption is another advantage of the new technology.

Separating carbon dioxide from gas streams resulting from combustion can also increase production in oil fields after injecting the obtained carbon dioxide in the field.

According to a research available online on the internet, solid adsorbents, such as zeolites and activated carbon, can be used to separate CO2 from gas mixtures. In pressure swing adsorption (PSA), the gas mixture flows through a packed bed of adsorbent at elevated pressure until the concentration of the desired gas approaches equilibrium. The mentioned bed is regenerated by reducing the pressure.
