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.

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)

Total |

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
