Kim Il Sung University has recently developed and introduced Korean-style advanced analytical equipment into the large oxygen plant of the Hwanghae Iron and Steel Complex.

Introduced into oxygen plant workshop No. 3 for the first time, the equipment piece is an infrared gas analyser which can measure with a high degree of accuracy the very low concentration of carbon dioxide, which needed an urgent solution for the operation of the oxygen plant.

The analyser was newly developed by scientists of the nonlinear optics research group of the Physics Faculty of Kim Il Sung University, the first natural science prize winners of the country. It can measure the concentration of carbon dioxide under 1 ppm.

It was an important matter to accurately measure the infinitesimal quantity of the concentration of carbon dioxide in real time in the normal operation of the newly-built large oxygen plant for the revitalization of production at the energy-saving oxygen blast furnace.

Scientists jumped into the new research project to solve this urgent problem in normalizing Korean-style iron production on a high level.

Prof. Im Song Jin, candidate academician, PhD and section chief of the faculty, and other scientists had already had rich experience of having developed and introduced highly effective infrared gas analysers into several important units to boost production in the chemical industry sector and achieved successes in the advanced basic research into the exceptional response characteristics of materials in the infrared band. They concentrated their thinking and efforts on developing a piece of advanced analytical equipment capable of measuring the infinitesimal quantity of the concentration of carbon dioxide with a high degree of accuracy free from the ready-made ideas.

As a result, they settled the major scientific and technological problems that would make a breakthrough for it in May and successfully made a new piece of advanced analytical equipment, whose performances are incomparably higher than the previous infrared analysers, in just two months after the start of the full-scale research project.

They proved its reliability through the successful field testing of the new analytical equipment and succeeded in its first test run by introducing the infrared analyser into a large oxygen plant on a trial basis.

The introduction of the advanced analytical equipment, which plays such an important role as an eye for the management of processes in the operation of the large oxygen plant, provided the material and technical foundations for improving the level of scientific operation of the oxygen plant, opening another good prospect for normalizing the Korean-style iron production by means of the energy-saving oxygen blast furnace on a high level.

The research finding has widely been introduced into several oxygen plants across the country, drawing attention of officials and experts of the relevant sector as it helps improve the level of scientific operation.
