Onsite Research
Process Development
The goal of Process Development research at NETL is to generate information
to help improve processes used in the production of materials that are being
developed to improve efficiency and performance of power plant operation.
Some of this research is helping to prove the feasibility of new fabrication
processes used, for example, to produce economical, high-performance solid
oxide fuel cells. In addition, process development research has a goal to
protect the environment by developing effective, reliable, and affordable
technologies for capturing and ameliorating the waste streams of fossil energy
power production. By developing innovations that will form the basis of future
power generation, process development is advancing the efficiency of the
Nation's energy systems by evaluating and improving processes in existing
power systems.
Process Development research specializes in the development of processes to:
- efficiently produce prototype parts, castings, and/or plate or sheet
from ferrous, non-ferrous, and refractory alloys;
- formulate and develop alloys for use in high temperature applications;
- recover or recycle valuable materials from wastes;
- improve material production by melting or smelting;
- develop processes for efficient carbon management including the sequester
of greenhouse gas emissions;
- improve efficiencies of high temperature melting or smelting systems;
and
- improve power plant efficiency, and reduce power plant emissions.
NETL understands and respects the need for confidentiality and the value
of intellectual property that is developed in the conduct of all research
conducted with industrial partnerships such as these. NETL partnership
agreements are designed to protect company-specific proprietary information
and intellectual property developed during a cooperative research agreement.
NETL continues to develop new partnerships to collaborate with industry,
for example, to s upport the development of new combustion technologies by
providing solutions to the complex interactions of high temperature combustion
and energy processes with the materials and metals that will be employed
in these service environments .
The Liquid Metal Processing (LMP) Laboratory provides capabilities to melt,
alloy, cast, forge, roll, and heat treat materials from a few grams up to
100s of kilograms. In addition, the division has a complete feed preparation
facility capable of crushing, grinding, sizing, mixing, and agglomerating
feed in batches from a few kg up to 1,000s of kg. For melting and smelting
experimentation, the PDD has a state-of-the-art facility that allows for
laboratory-scale (a few kg) up to pilot-scale (500 to 1,000 kg per hour of
product) experimental trials that can be designed to last from a few seconds
to more than 100 hours of continuous operation. With the excellent support
that includes a state-of-the-art analytical
laboratory , an outstanding mechanical testing facility, a world class metallography laboratory,
a unique corrosion
testing facility , and an experienced wear testing group, all products
can be given a complete characterization with respect to chemical and phase
composition, physical and mechanical properties, and wear and corrosion resistance.
