The New Project of Air Pollution Control on Thermal Plants

To combat air pollution, the Indian government suggested installing air purification equipment. In one of the Indian states, the authority is in charge of power production and delivery.

From the very beginning, they planned to arrange flue gas de-sulphurization (FGD) units on a thermal plant as an air treatment system. The flue gas de-sulphurization (FGD) units are utilized to control sulfur dioxide emission to comply with revised norms. There are several locations in India where these constructions are already installed. Mostly, they are used on coal-fired power plants as effective air treatment devices.

Therefore, employing contemporary air pollution control technologies, the government created an air pollution and control project. They decided to deploy FGD systems in the thermal plants as air pollution control devices. That would help to reduce flue gas emission and to improve the air quality. There are two types of FGD systems: dry scrubber and wet air scrubber. Taking into consideration all the information, the authority has finally decided to employ a dry flue gas desulphurization system. Despite all the wet scrubber design advantages, dry scrubbers are considered to have lower capital and annual costs than wet scrubber systems. Dry scrubbers require less water, are easier to operate, and have less complicated waste disposal process.

The owners of some of the plants formally requested a respite from the countrys air pollution prevention authority. The problem is that within a few years, certain thermal plants will be shut down. There’s no need for them to apply new air pollution control devices. The other reason is that the thermal units work only during paddy season when there is less pollution. Herewith, the present plant load factor is less than 15%.

These facts raise the issue of the requirement to deploy FGD systems. The manufacturers say that the thermal plants in India utilize Indian coals that have high ash content but do not have sulfur. Moreover, they should take into account the conditions of the thermal plants retirement. Furthermore, the plant load factor is low during the paddy season. It’s less than 20%, according to the statistics.

However, all manufacturers agree that there is a necessity for air treatment and air pollution control.

If you search for the best air treatment device to improve air quality, you can buy a high-tech completely new type of wet scrubber – a Multi-Vortex wet air scrubber produced by Redwood Technology.

Redwood technology is a fast-growing vendor of wet air scrubbers. The multi-vortex scrubber can remove gas emissions, dust, vapors, and other pollutants from a gas stream. It is an innovative technology created to save water that makes it more cost-efficient and differs from other types of scrubbers.  If you have any questions or would like to purchase a multi-vortex wet air scrubber, please contact us at info@rdwd.tech
