Company
ScanArc has 25
years experience of industrial plasma technology. We
provide proprietary technology in plasma processing
and environmental processing.
What we do
Our main objective is to provide, develop, service
and advice clients on processes and applications of plasma
energy in all pertinent areas of technology.
ScanArc's laboratory and pilot plant facilities in
Hofors , Sweden comprise the most advanced capability
in the world for developing new processes and applications
based on nontransferred plasma energy.
Our personnel represent many years of
experience in development, implementation and operation
of processes and applications in nontransferred plasma
arc energy. This experience is available on a consulting
basis to provide engineering, technical, economic,
operational
and marketing services with emphasis
on the metallurgical,
chemical and environmental
process areas that ScanArc is
expert in.
Improving the environment
In recent years ScanArc has completed a very successful
development utilizing the outstanding properties of plasma
technology for thermal decomposition of both organic
and inorganic compounds.
Since the plasma represents an independently controlled
source, it is possible to chose between reducing and
oxidizing conditions, whichever is most suitable for
the actual material.
This new branch of technology has been used to successfully
demonstrate the following applications on large pilot
plant scale. Complete decomposition of chlorinated hydrocarbons,
including PCB. Decomposition of compunds containing NO3-,
NHx or CN-groups without incurring NOx-formation. Destruction
of municipal waste material by conversion into a nonhazardous
fuel gas and nonleachable slag.
The History
In 1972 SKF Steel in Hofors, Sweden, embarked on a
long-range program to develop cleaner and more efficient
processes for steelmaking and other metallurgical applications.
One area that appeared to offer considerable promise
was energy supply based on plasma generators, but the
generators available at that time did not have the necessary
reliability, capacity or efficiency. Therefore a program
were started to develop industry-worthy plasma generators.
The intensive work paid of well in the early 1980's
in the form of a rugged, reliable and efficient nontransferred
segmented-arc plasma generator capable of delivering
10MW.
The first commercial plant based on these generators,
ScanDust at Landskrona and SwedeChrome in Malmoe were
comissioned in 1984 and 1986 respectively.
In 1988 SKF's intention was to concentrate on its other
businesses and ScanArc Plasma Technologies was found.
The company was based on the personnel and facilities
of SKF Plasma Technologies AB, to carry on the development
and implementation of nontransferred arc plasma energy
in industrial applications. The company is now controlled
by its 20 employees.
Commercial plants

The first commercial plant was the ScanDust AB in Landskrona.
The plant reclaims gas cleaning dust to steel industry
and treat 60000 metric tons of dust per year.
It is powered by three 6MW plasma generators and operates
continously on dust from stainless steelmaking.
The dust is mixed with coal powder, sand and recycled
process waste and is injected pneumatically into the
lower part of a coke-filled shaft provided with the plasma
generators.
Most of the metal in the dust is obtained as an alloyed
hot metal with a metal yield for metals like Ni and Mo
of more than 98%. The solid wastes produced include nonhazardous
slag, which can be used as a construction aggregate and
calcium flouride sludge which is landfilled.

The latest commercial plant is an Arc Fuming process built in Höyanger, Norway, for Eras Metal AS. It is built to recover zinc oxide from steel plant dust. The plant has a capacity of 40 000 ton of dust per year.
