Flue gas desulphurisation uses and perspectives

In accordance with the environmental impact of power plants that run on certain challenging coal types flue gas desulphurisation (FGD) solutions need to be developed in order to achieve higher treatment quality and maximum operating efficiency.

FGD technology is built on the chemical reaction that occurs between the warm exhaust gases and limestone. This reaction subsequently reduces around 90% of sulfur dioxide from the flue gas. The primary use of FGD technology is in coal-fired power stations, where it is used to remove exhaust fumes, also known as flue gas, that contains amounts of sulfur. Sulfur dioxide scrubbing process is another name that is used to describe FGD technology.

The segmentation of flue gas desulphurization market can be done by method, by type and by application. Based on methods of treatment the flue gas desulphurization market can be divided into SNOX, wet sulfuric acid process and scrubber. The latter can also be segmented into the following types of processes: dry and semi-dry. The segmentation of FGD technology into once through and regenerable is based on the solid or flue gases generated by the industry processes.  The first type of system disposes the waste sorbent and the second type recycles the sorbent. Regenerable systems cost more than the once through systems. Both types of systems can be categorized as wet, dry and semi-dry. The maintenance and operation of dry FGD are more expensive than those of wet FGD.

Global flue gas desulfurization market is predicted to rapidly rise in the next 3 years, so the demand for FGD systems will grow exponentially in accordance with government regulations that require these systems to have higher treatment quality in regard to exhaust fumes. The key reason for such high demand is a development of numerous emerging economies that use coal-fired power plants. Flue gas desulfurization is used in multiple applications, reagent and replacement applications being one of them. Another reason that explains fast growing demand is a rise in equipment repairs for FGD systems that are already in active use.

Out of all the different types of FGD systems, wet FGDs currently dominate the market as they offer an increase in treatment quality compared to other methods and easier maintenance characteristics.

Optromix Company offers a new type of wet air scrubber – Scroiler™ that can be installed for more effective air pollution control. Reference list includes more than 100 Scroiler™s installed since 2011 with 3 000 – 200 000 cfm capacity. Being a new type of wet air scrubber, Scroiler™ cleans air from gases, dust, vapors and other admixtures using water or other cleaning liquid.
