Using Wet-FGD systems for mercury removal
Journal of Environmental Monitoring, 2005A plan to control mercury emissions to the atmosphere and to establish mercury emission limits has recently been elaborated by the European Commission, making it necessary to devise an efficient and cost effective mercury removal technology. Towards this end wet flue gas desulfurization units appear as a promising option for multi-pollutant control ...

FGD Materials Guideline and Software
CORROSION 1993, 1993Abstract Corrosion and erosion have been main causes of failure and shutdown in first-generation flue gas desulfurization (FGD) systems. A wide variety of construction materials have been used and new materials are continually being tested and applied, with varying degrees of success.

Use of FGD gypsum in fire resistant panels
Waste Management, 2010Gypsum from power plant flue gas desulphurization units (FGD gypsum) is a combustion by-product produced in high quantities. In this paper, gypsum panels composed of 100% FGD gypsum from two power plants have been subjected to different physico-chemical (density, pH, humidity), mechanical (flexural and compressive strength, surface hardness, impact ...

Predicting the Corrosivity of an Operating FGD System
CORROSION 1994, 1994Abstract One of the key factors that influences the materials selection process for a FGD system is the anticipated environmental conditions. Due to the wide variations in coal burned, a method was needed that could predict the environment that would be generated. A computer model has been generated that will predict, with some degree of

Lining installation and performance in FGD systems
Materials and Corrosion, 1992AbstractAvailability and reliability of pollution control equipment have become important issues in recent years. Critical components such as scrubbers, ductwork, tanks, and stacks must be protected to withstand the corrosive environments that are characteristic for pollution control systems.

It is shown that it is possible to produce compacted gypsum with a low porosity and a high strength on a laboratory scale by uniaxial compaction of flue gas desulphurization (FGD-) gypsum powder. Compacted FGD-gypsum cylinders were produced at a compaction pres-sure between 50 and 500 MPa yielding porosities after compaction between 21 and 6% and ...

Phosphogypsum as an alternative to FGD gypsum
The University of Applied Sciences Nordhausen is currently conducting research projects on the topic of resource conservation. For example the separation of different materials with the aim of recycling or utilising them as a source of raw materials / secondary raw materials.Klausing, Julia*, Wudtke, Robert

Bigeminal tank for FGD wastewater treatment
Filtration + Separation, 2017Abigeminal tank is a key part of the flue gas desulfurization wastewater treatment process for heavy metals and the precipitation and removal fine of particles. This article investigates treatment process simplification and equipment structure modification to reduce both operational costs and deposition of particles.

Epoxy Resin Systems for FGD Units
CORROSION 1984, 1984Abstract Early work in the area of coatings for Flue Gas Desulfurization (FGD) units indicated that epoxy-based coatings were not suitable for this application. This work addressed itself to the "conventional" epoxy maintenance coating system.

Effect of Environment on Coatings in FGD Ductwork
CORROSION 1996, 1996Abstract A partial factorial experimental design was implemented to determine the main effects of 16 environmental factors on the performance of coatings used for outlet ducts in wet FGD systems. Suppliers applied their coatings, which included three epoxies, two vinyl esters, two fluoropolymers, and a polyester, on 7 in. by 7 in.
