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.
