Flue Gas Desulfurization
Limestone Handling
Our expertise in bulk material handling systems has served the electric power-generation industry for over one hundred years. We execute turnkey contracts to engineer and build new or retrofitted handling systems that process limestone for utilization in flue gas scrubbers. Roberts & Schaefer can customize our service offering to the precise level of assistance you need—from conceptual and feasibility studies to complete facility design, engineering, construction and operation.
Processing limestone requires a careful understanding of handling fine, particle-sized material. Our engineer-designed limestone bulk processing systems protect limestone from the environment and control stray dust. Our limestone unloading systems are in service throughout the world. They receive, handle, mill, dry, and size the limestone before conveying the finished product for use or storage.
Gypsum Handling
As a waste product from a power station’s flue gas scrubber, gypsum is limestone that has absorbed sulfur compounds released as effluents during the burning of fossil fuels. Gypsum-handling systems consist of components that move, temporarily store, and load onto the gypsum onto barge, rail or truck for shipment to its ultimate off-site destination.
Roberts & Schaefer offers versatile bulk material handling expertise. We provide each utility with over 100 years of innovation in design, engineering and construction management as well as a reputation for quality systems analysis and specialized equipment manufacturing. For complete new system development, upgrades or modifications to existing bulk material.
