  • 6 Facts about Synthetic Gypsum FEECO International Inc.

    3. FGD Gypsum is Created at Power Plants. FGD gypsum is formed when fossil-fueled power plants utilize flue gas desulfurization systems to remove sulfur dioxide from gas pollutants. Using a process referred to as ‘scrubbing,’ gas pollutants are fed through calcium carbonate to eliminate impurities and environmental concerns.Онлайн-запрос

  • FGD Gypsum Introduction

    The term "synthetic gypsum" has been used widely to encompass materials produced by a variety of industrial processes. In addition to FGD gypsum, synthetic gypsum includes materials such as phosphogypsum, (a byproduct of processing phosphate ore to make phosphoric acid), Titanogypsum (a byproduct from the production of titanium dioxide), fluorogypsum (a byproduct from the production ofОнлайн-запрос
