United States Limestone in Flue Gas Desulphurisation Market Report and Forecast 2025-2034

The United States limestone in flue gas desulphurisation market attained a volume of about 4796.00 KMT in 2024.

The Rising Levels of Air Pollution in the Region is Invigorating the Market Demand for Limestone in Flue Gas Desulphurisation

The United States market for limestone in flue gas desulphurisation is being aided by the widespread availability, low purchase cost, and the ease of disposal of limestone. Flue gas desulphurisation is an important technique to control the spread of air pollution and airborne diseases from the toxins released as a result of SO2 emissions from industries like municipal, medical waste, industrial boilers, and combustion units, among others in the United States of America.

Limestone is one of the sorbents widely used in flue gas desulphurisation systems owing to its applicability in the wet lime method and in fluidised bed boilers. However, the COVID-19 pandemic resulted in restricted market growth due to disruptions in supply chains, which obstructed the manufacturing industry in the region.

Limestone in Flue Gas Desulphurisation: Market Segmentation

To remove sulphur oxides (SOx), the flue gas is brought into intensive contact with a slurry containing an additive in the absorption zone. Limestone is actively used for cleaning the flue gas and is continuously added to the absorber sump in order to ensure uniformity of the system’s cleaning capacity.

On the basis of lime type, the market can be divided into:

• Limestone
• Quick Lime
• Hydrated Lime

Based on process type, the market can be segmented into:

• Wet
• Dry

The market, based on end-use, can be categorised into:

• Power Generation
• Chemical
• Iron and Steel
• Cement Manufacturing
• Others

The Widespread Availability of Limestone Deposits Across the US is Propelling the Growth of the Market

Limestone is an essential raw material used in FGD systems across the country to control suphur dioxide emissions, considering lime is an excellent sorbent used in many air pollution control applications. The United States has numerous limestone deposits with large seams in Appalachia, the Ohio Valley, the Southeast (particularly in or near Florida), the Mid- and Upper-Mississippi Valley and in the Central- and Southern-Plains. This is a major driving factor positively influencing the growth of the market in the region. In addition to this, high quality limestone whose calcium carbonate content is at or above 95% are also commonly available in many seams and exhibit fruitful results in the flue gas desulphurisation process, hence augmenting the growth of the market. However, many formations contain fine grains of silica-bearing compounds commonly known as chert, which reduces the quality of the limestone, thereby restraining the growth of the market.
