Power engineers at Kamet Steel are overhauling the air separation unit

In the oxygen compressor shop at Kamet Steel, they are working on overhauling the air separation unit KAr-30 No. 3, designed to provide oxygen and nitrogen to technological processes in the main production units, primarily the converter and blast furnace, is underway. The main task of the overhaul is to restore the operability of cryogenic equipment for its safe inclusion in operation, since KAr-30 No. 3 has been in reserve idle for a long time.

In the work plan, priority is given to repairing cryogenic tanks and valves. Inspection of the main rectification unit is underway, as well as all internal metal pipelines. All internal cryogenic fittings are being inspected. Any technical problems discovered will be dealt with as part of this major overhaul. Specialist contractors are replacing shut-off valves on the nitrogen pipeline and partially renewing thermal insulation materials, restoring monitoring and measuring equipment, and so on.

An expert examination of cryogenic tanks, in which the process of air separation directly takes place and which operate under pressure, is also carried out in order to obtain permission for their further operation.

“This year, we are planning a significant major overhaul of the main air distribution unit of Kamet Steel AKAr-40/35. At the time of its shutdown, backup equipment, specifically the KAr-30 No. Three units will be used to carry out technological tasks to supply production units with air separation products, and they need to be technically prepared for these tasks. "Thanks to high-quality repairs, we will be able to safely put this technological unit into operation in compliance with current state requirements and ensure a stable production of up to 25 thousand cubic meters of oxygen per hour," said Andrii PYSMENNYI, Head of the Oxygen Compressor Shop.
