Gypsum Dewatering is the Hot Topic Hour for Thursday, January 24, 2013

While the decision on whether an FGD system should produce disposal-grade or commercial-grade gypsum is primarily based on economic factors including the availability of a market for the gypsum; dewatering is an essential process in either case. The objective is to meet the requirements for the disposal method at the minimum operating cost. In previous Hot Topic Hours, participants have demonstrated that basket centrifuges in use since the 1980s and vertical centrifuges can deliver gypsum with 90 to 95 percent solids with lower maintenance and energy costs than typical belt filters. Rotary drum vacuum filters can also offer reduced cost in some situations. Lower capital equipment cost and lower operating cost when compared to a belt vacuum filter have been reported. However, belt filters may be the choice as the volume of gypsum to be dewatered increases. Factors to consider when specifying a de-watering system or belt material for dewatering and washing are:

·         Volume of material

·         Temperature

·         Particle size distribution "PSD"

·         Concentration of gypsum in the slurry

·         Concentration of Cl- in the feed liquor

·         Vacuum pump capacity

·         Energy consumption

·         Maintenance requirements

·         Space required

The following speakers will address these and other issues related to gypsum dewatering systems, provide a comparison of the various dewatering systems and discuss the dewatering system best suited for specific plant configuration and gypsum dewatering objectives.

Steve Myers, Industry Manager, North America Region for Mining & Minerals at ANDRITZ Separation, will discuss the broad range of solid/liquid separation and drying solutions that ANDRITZ Separation offers to the minerals, chemical, food & pharma and environmental industries.

Progress with Smart Valves Will Lead to 10 Percent Higher Growth in the $55 Billion Valve Industry

McIlvaine Company has revised its forecast for growth in the industrial valve industry over the next five years. The current forecast is for 5 percent growth. This is being revised to 5.5 percent CAGR for the 2013-2017 period. The basis is the increased anticipated revenues from the sales of smart valves. This is the latest forecast in Industrial Valves: World Markets published by the McIlvaine Company.  (www.mcilvainecompany.com)

The valve forecasts are defined to match the individual valve supplier revenues, so they include smart valve technology where it is sold by the valve supplier but not by an independent automation supplier.

The biggest growth will occur in Asia (including the Middle East and two of the BRIC countries (China and India).  The oil and gas sector is leading the way toward smart valves.  For sub-sea oil and gas, the use of intelligent control systems for valve trees is becoming a defining factor of intelligent well development.  All electric subsea production control systems are replacing industry standard electro-hydraulic control systems, with the aim of making them more reliable, more responsive and more cost effective.

The oil and gas industry is moving toward valve technology with embedded processor and networking capability to work alongside sophisticated monitoring technology coordinated through a central control station.  The goal has been to link control valves to an extended data network, coordinating control valve operation with the increasingly detailed data available on flow rates and operating conditions. Connecting valves to a network allows distributed control, which can enable operators to reconfigure piping and networking systems so that a field can continue producing even if there is a blockage in, or damage to, the pipeline network.

Another goal is to develop valves that consume less power to create systems that can be deployed in applications where conventional valves cannot be used due to the lack of power.

One manufacturer leading the way in smart valve development is Emerson Process Management.  The range of high-performance Fisher digital valves enabled the implementation of customized valve designs to cope with the pressure, flow capacity and temperature demands of the world's first twin-mega-train LNG plant.

The Yokogawa Exaquantum/SSP provides continuously updated subsea valve information from FMC Technologies SSH (Subsea Historian). This timely information enables users to take appropriate action if problems are detected, avoiding lost production.

Pressurized Oxy-Combustion is Just One More Route to Clean Coal

Clean energy from coal is a multibillion dollar industry which will grow rather than shrink. This is the conclusion reached by McIlvaine in Fossil & Nuclear Power Generation: World Analysis & Forecast.  (www.mcilvainecompany.com)

 

One of the biggest drivers for clean coal will be use where it is greener than solar or wind.  This will occur when a combination of coal and biomass are burned in an oxy combustion system.   All the gases (CO2) are sequestered and used for enhanced oil recovery.  There are no emissions and there is a net reduction in the world’s CO2 in the atmosphere for every unit of energy generated.

The U.S. DOE as well as countries in Europe and Asia are funding programs to further oxy combustion. Two approaches in the U.S. include combustion at normal pressure and combustion at high pressure.  Recent research shows that if combustion takes place at the pressures experienced by separating the oxygen from the air, there are multiple benefits including total parasitic energy reduction. The energy to compress CO2 is substantial, so eliminating this step is significant.

There is progress being made on ultra supercritical coal firing. This approach will significantly improve the conversion efficiency particularly when compared to older power plants operating in the U.S. and elsewhere.  The biggest and quickest impact to make coal cleaner would be to replace all old power plants with ultra supercriticals.  The capital cost would be more than offset by the 30 percent reduction in coal consumption.  This new generation of power plants could be retired in twenty-five years and still provide a more economic bridge to renewables than retaining the old coal fleet.

The steam plume associated with coal plants is testimony to inefficiency. This plume can be eliminated and the heat efficiently used to make ethanol or heat sewage sludge. In fact, the co-location of sewage treatment plants and coal-fired generators should be the wave of the future.  Existing coal plants can practice sewer mining and treat all the municipal sewage in the surrounding area. They can then use the treated wastewater for cooling and other purposes.

Coal complexes making power and liquid fuels are already a reality.  In fact, there are large numbers of plants under construction.  China is leading the way, but there are projects in many other countries.  At the present price of oil, it is economically attractive to make gasoline from coal.

Many of these technologies can be applied to existing power plants.  In fact many of the old coal-fired power plants are located in areas where there is a need to dispose of large quantities of municipal solid waste.  This waste can be gasified and used as a reburn fuel in coal-fired boilers. The net effect is a big reduction in emissions compared to alternatives.

Generation of useful byproducts can more than offset the emissions of alternative production of those byproducts. Rare earths can be extracted from flyash. Sulfuric acid, hydrochloric acid, magnesium hydroxide and gypsum can all be economically produced along with power
