Power Plant FGD Gypsum

Description

1. Product Overview

Power Plant FGD Gypsum is a high-purity synthetic calcium sulfate dihydrate (CaSO₄·2H₂O) produced through flue gas desulfurization (FGD) systems in coal-fired power plants. It serves as a premium alternative to natural gypsum, primarily used in cement production, gypsum board manufacturing, and agricultural soil conditioning. With consistent chemical composition and controlled particle characteristics, FGD Gypsum delivers reliable performance in large-scale industrial applications. Strategically, it supports circular economy initiatives by transforming emissions control by-products into value-added raw materials, aligning industrial operations with cost efficiency and environmental compliance.
